Solanum Lycopersicum L

Tomato (Solanum lycopersicum L.) is a broadly consumed fruit vegetable globally. It is one of the research mandate vegetable of the National Horticultural Research Institute (NIHORT), Ibadan, Nigeria. The institute’s contains diverse collections of tomato accessions and wild relatives, without utilization information for the African continent. With the decline in diversity and potential of cultivars, a robust tomato breeding pipeline with broad genetic base that eliminates redundancy in the development of lines with desired horticultural traits is paramount. This study evaluated the mean performance and variations of thirteen wild tomato accessions obtained from the C.M. Rick Tomato Genetic Resource Center, University of California, Davis, USA, evaluated for agronomic, nutritional and physicochemical traits under a rain forest zone in Nigeria. The accessions were planted and grown in three replications with randomized complete block design. Agronomic traits, physicochemical and nutritional parameters were measured and analyzed. There was significant (P < 0.001) variation among accessions for all traits measured. Accession LA0130 was separated from others by cluster analysis and was outstanding for its unique attributes which include: fruit yield parameters, total soluble solids, acidity and content. The principal component analysis suggests fruit yield related traits, acidity and contributed most to the variation among the 13 accessions. The results obtained can be used to breed materials adapted to a rain forest . These wild tomato accessions have genes with desirable agronomic, nutritional and physicochemical traits that could be into breeding lines to improve commercial tomato varieties.

The general combining ability (GCA), specific combining ability (SCA), and heterosis were studied in a complete diallel cross among fresh market tomato breeding lines with reciprocal excluded. Fifteen genotypes (five parents and ten hybrids) were tested using a randomized complete block design, with three replications, and the experiments were conducted in Itatiba, São Paulo state, Brazil, in 2005/06. The yield components evaluated were fruit yield per plant (FP), fruit number per plant (FN), average fruit weight (FW); cluster number per plant (CN); fruit number per cluster (FC), fruit wall thickness (FT) and number of locules per fruit (NL). Fruit quality components evaluated were total soluble solids (SS); total titratable acidity (TA); SS/TA ratio, fruit length (FL); fruit width (WI); length to width ratio (FL/WI). The data for each trait was first subjected to analysis of variance. Griffing's method 2, model 1 was employed to estimate the general (GCA) and specific (SCA) combining abilities. Parental and hybrid data for each trait were used to estimate of mid-parent heterosis. For plant fruit yield, IAC-2 was the best parental line with the highest GCA followed by IAC-4 and IAC-1 lines. The hybrids IAC-1 x IAC-2, IAC-1 x IAC-4 and IAC-2 x IAC-4 showed the highest effects of SCA. High heterotic responses were found for fruit yield and plant fruit number with values up to 49.72% and 47.19%, respectively. The best hybrids for fruit yield and plant fruit number were IAC-1 x IAC-2, IAC-1 x IAC-4 and IAC-2 x IAC-5, for fruit yield and plant fruit number, the main yield components.

AbstractEvaluation and characterization of sunflower hybrids using morphological, physiological and biochemical data are necessary and essential in sunflower breeding programs. The aim of this paper was to evaluate the productive possibilities of some sunflower hybrids grown in Macedonian environmental conditions. The experiment was carried out during the period 2013 and 2014 on the research field of the Faculty of Agriculture, “Goce Delchev” University – Shtip, in Ovche Pole locality, Republic of Macedonia. Total 20 sunflower hybrids were used as an experimental material. The trial was arranged as randomized complete block design (RCBD) with three replications. The average content of oil and oleic acid were 45.6 and 65.2%, respectively. The highest seed yield from all sunflower hybrids was obtained for the hybrid NLK12M144 (3,344 kg ha–1) and the lowest for hybrid NLK12S126 (2,244 kg ha–1). Cluster analysis classified the sunflower hybrids into four groups based on agronomic traits and seed yield. Most of the hybrids were included in cluster I and III (7 hybrids) followed by cluster IV. Using principal component analysis two main components have been extracted, with eigenvalue greater than one. They account for 72.99% of the variability in the original data. Only four hybrids had positive values for both main components (NLK12M144, NLK12S070, NLK12S125 and NLN12N011 DMR). The results from this study can be used to identify the best sunflower hybrids grown under Macedonian environmental conditions and to select the superior hybrids for future exploitation.

This study assessed variability, heritability and correlations of agronomic traits in an onion (Allium cepa L.) landrace and derived S1lines after a single selfing generation. Bulbs used to develop S1lines were selected for shape, colour and high number of skins. Fifty-one S1lines and the original population were evaluated using an incomplete random block design. The original population and S1lines were highly diverse for quantitative and qualitative traits. S1lines were significantly different, with transgressive segregation for number and maximum leaf length, bulbing index, bulb weight, diameter, and dry matter content. Variances within S1lines were greater than among S1lines for all traits. Bulb colour and number of skins responded to selection. Heritabilities for dry matter and soluble solids were 52.6% and 36.1% respectively. Both traits were highly correlated. The development of S1lines allowed the expression of genetic variation and the identification of better genotypes for agronomic traits of interest.

Faba bean (Vicia faba L.) is a high value crop in Ethiopia and has versatile uses. The national faba bean breeding program concentrates on the three major traits (grain yield, disease resistance and seed size) of the crop for varietal release for commercial production. Hence, ten faba bean genotypes were evaluated at Adet, Areka, Bekoji, Haramaya, Holetta and Jimma during the main cropping seasons of 2018 and 2019 using a randomized complete block design with four replications with the objectives to select the genotype with best performance in terms of important agronomic traits like grain yield, disease resistance, large seed size and other desirable agronomic traits for high potential production areas in Ethiopia. The combined analysis of variance across locations revealed that there is highly significant (P < 0.01) variation among the tested genotypes for grain yield, 1000-seeds weight, number of pods per plant, and days to 90% physiological maturity. The genotype EH011089-3 showed better performance than the tested genotypes having comparable grain yield performance (3803 kgha-1) with the two standard checks, Numan and Gora (3790 and 3897 kgha-1, respectively) while it had the highest 1000-seeds weight (1065 g) compared to the two standard checks, Numan and Gora (937 g and 786 g, respectively), i.e., 13.7% and 35.5% advantage, over the two standard checks, respectively. Additionally, EH011089-3 had better resistance for chocolate spot and rust diseases. Therefore, EH011089-3 was the best over the tested varieties and breeding lines. Genotype EH011089-3 is recommended for varietal release for commercial production all over in Ethiopia.

Field study was conducted at the Botanical Garden, Federal University of Lafia, between August and October 2017 to investigate the effect of alpha nano spin on nine advanced varieties of cowpea obtained from Institute of Agriculture Research (IAR), Zaria and one local variety from Nasarawa Agricultural Development Program (NADP), Lafia which served as the control. These seeds were exposed to alpha-spin nano-particles at four different periods; 20 mins, 40 mins and 60 mins termed as T1, T2 & T3 respectively while the untreated seeds 0 mins were termed T0 (control). The experimental design was a Randomized Complete Block Design with four replications. Data were collected on agronomic traits, yield components and grain yield, which were subjected to Analysis of Variance and Principal Component Analysis. Laboratory studies were also carried out to determine the pattern of Dry matter accumulation at two weeks interval for six weeks. Results of harvested seeds revealed that Sampea 5, inoculated at 40 mins treatment produced black seeds colour from brown seed colour parent. Results also showed a significant difference among treatments and varieties for mean plant height, the mean number of leaves, mean number of pods and mean pod length. Total dry matter accumulation of leaves, 100 disc leaves and stems over time varied among treatments and varieties. The first three Principal Components (PCs) accounted for 83.1% of the total variation implying their high selection stability. The detailed results are presented and discussed in this paper as a measure of the future selection of useful variants of the improved cowpea for sustainable cowpea production.

An experiment was conducted to evaluate the performance of hybrid tomato lines on growth and yield performance at Regional Agriculture research Station (RARS), Parwanipur, Nepal during end of September, 2018 to April, 2019. The experiment was laid out in randomized complete block design (RCBD) with seven hybrid tomato lines as treatments and three replications. The tested lines included Srijana and Dalila as check varieties and other lines, developed by crossing HRA and HRD lines which showed better performance under late blight conditions. HRA 20× HRD 1 showed significantly higher plant height (110.67 cm) which was statistically at par with genotype HRA 14× HRD 7. The highest number of fruits per plant (69) was recorded from Srijana whereas the lowest number of fruits per plant (37) was recorded from cv. HRA20 × HRD1. The fruit yield of the lines ranged from 50.54 t/ha to 32.2 t/ha with Srijana having the highest yield and HRA 20× HRD 1 as the lowest. Similar results were shown regarding the marketable fruit yield. However, the highest individual fruit weight (34.67g) was recorded in HRA 14× HRD 7 and the least fruit weight was recorded in Srijana (24.22 g). Results showed that the maximum TSS (5.53 0Brix) was recorded from Dalila which was similar as Srijana. Hence, the overall performance of Srijana was recorded superior regarding both quantitative and qualitative suggesting Srijana as the recommended variety in the given domain. Here authors concluded that Srijana is still a comparatively better hybrid variety in Nepal.

ABSTRACT Changes in plant architecture, such as apical pruning and harvesting at the right time, are management practices to obtain not only greater fruit production, but mainly quality and pungent fruits, preferred by the consumer market. We evaluated the effect of management of pruning and harvest seasons on growth, production and pungency of fruits conducted in the field. Nine seasons of harvest were studied {90, 101, 116, 131, 146, 161, 176, 191, 206 and 221 days after transplanting (DAT)} and two management systems (pruning and no pruning). The treatments were arranged in a factorial design (9x2) with split plot in a randomized block design with three replications. The agronomic traits analyzed were: height, chlorophyll, leaf area, soluble solids, number of fruits and pepper yield. The content of capsaicin and dihydrocapsaicin was determined using fruits harvested in two seasons (146 and 161 DAT) and in management systems (pruning and no pruning), in a factorial scheme (2x2), in a randomized complete block design with five replications. Growth and production traits did not differ significantly for pruning and no pruning managements, with an average of 71.8 fruits/plant and productivity of 429.7 g/plant. The agronomic traits were adjusted to the quadratic model. The maximum yield (529.09 g/plant) and the maximum number of fruits per plant (95.34) were estimated at 164.83 and 163.21 DAT, respectively. The use of pruning resulted in fruits with a higher content of capsaicin (363.89 mg/kg) and dihydrocapsaicin (198.27 mg/kg) at 161 DAT. Pruning management results in more pungent and better quality fruits for industry, and the maximum production of BRS Mari pepper was estimated at 164.83 DAT, important information for pepper producers, in order to schedule the harvests.

The aim of this study was to compare the effects of foliar fertilization with a nitrogen (N) fertilizer containing nanoparticles (nN) with those of foliar fertilization with urea on the characteristics of pomegranate fruits cv. Ardestani. The experiment was carried out using a completely randomized block design with five treatments and four replications (trees) per treatment during two consecutive years, 2014 and 2015. Two foliar applications of nN (0.25 and 0.50 g N/L, equivalent to ≈1.3 and 2.7 g N/tree or 0.9 and 1.8 kg N/ha; nN1 and nN2, respectively) and urea (4.6 and 9.2 g N/L, equivalent to ≈24.4 and 48.8 g N/tree or 16.3 and 32.5 kg N/ha; U1 and U2, respectively) were applied at full bloom and 1 month later, and trees not treated with any N fertilizer were used as a control. Results show that foliar N fertilization increased fruit yield (by 17% to 44%) and number of fruits per tree (by 15% to 38%). The highest fruit yields (17.8 and 21.9 kg/tree) and number of fruits per tree (62.8 and 70.1/tree) were obtained with the treatment nN2 (1.8 kg N/ha), whereas the lowest fruit yields (12.4 and 16.2 kg/tree) and number of fruits per tree (45.5 and 55.3/tree) were recorded in the control trees. The treatments U1 and nN2 increased fruit length (the latter only in the second season), whereas the treatment U1 increased average fruit weight (10% to 11%). The treatment nN2 increased aril juice and total soluble solids (TSS) in both seasons and titratable acidity (TA) only in the first one, whereas the treatment U1 increased TSS in both seasons and aril juice and TA in the second season. Treatments nN2 and U1 also increased total sugars and decreased total anthocyanins. On the other hand, fruit diameter, fruit cracking, peel thickness, aril content, weight of 100 arils, juice pH, maturity index, antioxidant activity, and total phenolic compounds were unaffected by N fertilization. Nitrogen fertilization increased the leaf concentration of N, whereas the leaf concentrations of P, K, Mn, and Zn were unaffected. Results indicate that pomegranate fruit yield was improved similarly with two applications (at full bloom and one month later) of nN fertilizer at a rate of 1.8 kg N/ha and with two applications of urea at a rate of 16.3 kg N/ha. Furthermore, fruit quality was improved more with the nN fertilizer at a rate of 1.8 kg N/ha than with two applications of urea at a rate of 16.3 kg N/ha.

Tomato a highly nutritious and income relevance crop. The optimum productivity is constrained by a number of factors such as soil fertility management. A field experiment was conducted at Teaching and Research Farm, Federal University of Technology, Akure, Nigeria between December 2012 to April 2013 (irrigated) and March – August 2013 (rainfed) to investigate the effect manuring on the growth and yield of tomato varieties. Four manuring sources (Organic, Organo-mineral, Urea and No fertilizer) and four tomato varieties (Beske, Ibadan local, Roma and UC) laid out as a randomized complete block design in a factorial arrangement and replicated three times. Results showed that manuring influenced on set of flowering in tomato, organic fertilizer prolonged day to anthesis (22.72 day) closely followed by organomineral (22.49 days) while control (no fertilizer) was earliest (20.88 days). Beske significantly showed earliness to flowering, Ibadan local and Roma were delayed but had similar flowering dates (P≤ 0.05). The varieties had distinct fruit yield responses to fertilizer application, fruit produced were in order of Beske, Ibadan local and UC (721.9;626.4) g;(683.6; 696.2) g; (550.0; 463.6) g (384.4; 431.5) g for rainfed and irrigation respectively. Varietal effect was significant on fruit yields for irrigated, Beske recorded heaviest fruit yield (6.03g) followed by Ibadan local (4.72), Roma (2.6) and UC (2.14). Harvested fruit among the varieties in both seasons were (3978.5t/ha;3484.9t/ha;1229.8t/ha and 985.2 t/ha) and (3947.2t/ha; 3452.8t/ha; 1197.8t/ha; 953.2t/ha) for Beske, Ibadan local, Roma and UC respectively. Fertilizer application were significant for both season on harvested fruits weight in magnitude order of Organomineral, organic fertilizer urea and control (3535.9;3503.9t/ha),organic fertilizer (2935.2;2903.2t/ha), Urea (2078.8;2047.4t/ha) and control (1128.0;1096.5t/ha). Beske and Ibadan local varieties performed better in the rainforest zone of Nigeria. Organic fertilizer sources complimented with mineral fertilizer timely applied with good agronomic managements are measures to enhance growth and yield performance of tomato.

The Tropics

The issue of low tomato production in the tropics like Ghana has been a long-standing challenge. The advent of greenhouse technology has not significantly improved the yield of tomato compared to Japan and the Netherlands. Immediate technological interventions are needed. Through hydroponics, the low-node order pinching at a high-density planting system has been recommended in some studies. This system was intended to be established in Ghana, and it would be expected to improve the yield and fruit quality of tomato. In effect, a study was carried out in the greenhouse, at Chiba University using this system. A tropical tomato cultivar (Jaguar) was evaluated with Momotaro York at 3.8 m s2 and pinched at the fourth truss. Data collected were water and nutrient use efficiencies, plant growth rate, dry matter partitioning, and fruit yield and quality, as well as some physiological characteristics. The experiment was laid out in a randomized complete block design with three replications. Results showed that Jaguar cultivar was two times more efficient in water and nutrient use than Momotaro York at first harvest. Root tissue density recorded in Jaguar was significantly lower compared to Momotaro York. The net assimilation rate (NAR) recorded was markedly higher in Jaguar than Momotaro York at last harvest. All the physiological attributes recorded in both cultivars were not significantly different. Plant dry mass (DM) recorded was similar in the two cultivars; however, the DM partitioned to fruits was 55% in Jaguar compared to 46.5% DM for Momotaro York. Fruit yield per area did not differ in the two cultivars. Fruit yields of 28.8 and 30 kg m−2 per year were recorded in Jaguar and Momotaro York, respectively. In comparison, this yield result is 1.2–1.25 times less and 14.4–15 times higher than current tomato yields recorded in Japan (greenhouse) and Ghana, respectively. Fruit quality, in terms of total soluble solids recorded in Jaguar cultivar being 5.4 %Brix, was within the 3.5–5.6 %Brix recorded in Ghana. This system could effectively enhance the yield and quality of tomato in the tropics as well as economising on the use of resources.
