In a field experiment, to identify the best sweet cherry varieties for high density orcharding, maximum canopy volume (18.94 cm3) was recorded in variety ‘Steela’ and minimum in ‘Lambert’ while, ‘Bigarreau Napoleon’ had maximum TCSA (213 cm2). Trees grown under HDP have lower TCSA in comparison to normal density. Primary and secondary branch girth were maximum in ‘Bigarreau Napoleon’ whereas, annual extension growth and shoot thickness were high in ‘Steela’. Yield, yield efficiency and cumulative yield efficiency were registered maximum in ‘Bigarreau Napoleon’ and ‘Bigarreau Noir Grossa’ cultivars. Largest fruit weight, fruit length and fruit diameter were found maximum (10.16 g/fruit), (25.51 mm) (25.20 mm) respectively in ‘Bigarreau Napoleon’. Total soluble solids were found maximum in ‘Bigarreau Noir Grossa’ (17.30 0Brix) among the studied cultivars. Correlation matrix showed that TCSA had positive correlation with canopy volume, primary branch girth and secondary branch girth and fruit weight showed positive correlation with fruit length and fruit diameter.

Some physico-chemical properties of ten pomegranate accessions collected from different districts in the Kurdistan region of Iraq were investigated in this paper. Considerable correlations between the characteristics studied were found and valuable pomological traits were observed. Cluster analysis showed the homonyms between some pomegranate accessions. Principle component analysis reported that the component describing the greatest variability also positively correlated with fruit weight, total aril weight, total peel weight, volume of juice, total soluble solids (TSS), fruit length, fruit diameter, pH, aril length, and 100-seed fresh weight, but negatively correlated with titratable acidity (TA). Fruit weight was firmly correlated with total aril weight, total peel weight, volume of juice, TSS, aril length, 100-seed fresh weight, fruit length and fruit diameter. The volume of juice was correlated with TSS, aril length, 100-seed fresh weight, fruit length, fruit diameter and it was observed that with an increase in the fruit size, the volume of juice increased as well. The correlation between total phenolic compounds and antioxidant capacity was not observed. The associations found among physical and chemical traits suggest that consumers should use large fruits with large arils so that they have more juice. Thus, ?Choman?, ?Raniyeh? and ?Halabja? were juicier than other accessions.

Nine different accessions of water apples were evaluated at Indonesian Tropical Fruit Research Institute(ITFRI), Solok, West Sumatera from January 2013 to December 2014. This present study was aimed to evaluate the variability, heritability, genetic advance and its characters in nine different accessions to provide useful information in the improvement program of water apples. The research used Randomized Complete Block Design (RCBD) with two replications. The ANOVA results exposed significant differences at 5% probability level for all characters. Genotypic variance on fruit weight, fruit length, fruit diameter, leaf length were broad. However, the genotypic variance on total soluble solids, leaf width were narrow. The phenotypic variation for all characters was broad. The heritability estimation was categorized as low, moderate, and high. High heritability estimation was recorded for fruit weight, fruit length, fruit diameter, and leaf diameter. Moderate heritability estimation was noticed for total soluble solids. Leaf width had low heritability estimation. High heritability and high genetic advance were observed on fruit weight.

Abstract In the field experiment, 8-year-old ‘Sylvia’ and ‘Karina’ sweet cherry trees grafted on ‘GiSelA 3’, ‘GiSelA 5’, ‘Piku 4’and ‘Weiroot 72’ clonal rootstocks were compared with trees of the same cultivars on the standard rootstock F 12/1. The data collected included tree vigour (expressed as trunk cross-sectional area − TCSA), yield, and fruit weight as well as content of soluble solids in fruit.Based on TCSA, the largest ‘Sylvia’ and ‘Karina’ trees were on ‘F12/1’, and the smallest were on ‘GiSelA 3’. The results revealed that all of the tested rootstocks being compared to ‘F 12/1’, significantly reduced the growth of sweet cherry trees.‘Sylvia’ trees on ‘GiSelA 5’ and ‘Piku 4’ yielded more than those on ‘F12/1’. The highest cumulative yields of ‘Karina’ were harvested from trees on ‘GiSelA 5’. ‘Karina’ trees on ‘GiSelA 3’, ‘Piku 4’ and ‘Weiroot 72’ performed comparably in cumulative yields to those on ‘F12/1’. Rootstock effects on yield efficiency were consistent between the two cultivars, with the most yield efficient trees on ‘GiSelA 3’, ‘GiSelA 5’ and ‘Weiroot 72’, and the least efficient trees on ‘F12/1’.Trees of both cultivars grafted on ‘GiSelA 3’ produced significantly smaller fruits than those grafted on ‘F 12/1’. The rest of the rootstocks, tested in terms of an effect on fruit weight (with the exception of ‘Karina’ on ‘Weiroot 72’), had a similar value to ‘F 12/1’. Effects of rootstock on content of soluble solids in fruit were modest and statistically insignificant.

Eleven morphologically diverse cultivated eggplant accessions were used for hybridization following half diallel mating design to obtain 55 hybrids. Evaluation of hybrids along with the parents was conducted over two locations followed by randomised complete block design with three replications to study gene action and combining ability of 15 morphological and biochemical traits. The analysis of variance indicated highly significant differences among the environments and interaction of genotype and environment, except for fruit length to width ratio. Additive gene effects were significant for the inheritance of these traits and expression of these additive genes were greatly affected by environments. The general combining ability (GCA) was greater than their respective specific combining ability (SCA) for all traits except for fruit yield per plant. High values of GCA and SCA effects for characters of interest were dispersed among different genotypes. From this study it was observed that the best parental line was BT15 based on days to first flowering, total number of fruits per plant, total soluble solids and total phenol content. Besides, the parent BM5 showed good general combining ability effects for fruit yield per plant, fruit length and fruit length to width ratio and the parent BB1 performed good general combining ability for fruit diameter, fruit girth and fruit weight. Besides, other parents showed the best performance for only one trait. On the other hand, the hybrid BT6 × BT15 was reported bearing early flowering with high total phenol content and the hybrid BM9 × BB26 has high fruit yield with high soluble solids. Besides, the hybrid BM9 × BB1 has a high fruit diameter and fruit weight. All other hybrids except for these three (BT6 × BT15, BM9 × BB26 and BM9 × BB1) were shown the best performance for only one trait. Hence, based on the desired trait, the hybrid can be selected for future use after large scale evaluation.

Cucumis melo L. is characterized with a great polymorphism according to many agronomical features. Study the variability of melon flowering and fruit traits is an initial step in the breeding program. The current study aimed to identify the genetic variability in the melon collection according to flowering and fruit traits in order to be used in breeding programs. It was evaluated fifty melon genotypes belong to different groups - cantalupensis, reticulatus, makuwa, inodorus, and agrestis. The studied collection consists of Bulgarian old cultivars, hybrids, landraces, PI, and introduced lines. Investigated genotypes were characterized by nine quantitative fruit traits - days to flowering, sex expression, days to ripening, fruit length, fruit diameter, flesh thickness, fruit weight, seed cavity diameter, and total soluble solids. It was established great variability in studied characteristics measured by a coefficient of variation from 7.73 to 39.85%. Significant correlations between fruit length, fruit diameter, flesh thickness, cavity diameter, and fruit weight were established. Principal component analysis grouped variables into three components which explain 69.89% of the total variation. Cluster analysis divided genotypes into six groups of similarities. Among the genotypes examined, they have a relatively high level of variability and their polymorphism could be used in a breeding program aimed at combining valuable characters.

Abstract. Mawasid FP, Syukur M, Trikoesoemaningtyas. 2019. Epistatic gene control on the yield of tomato at medium elevation in the tropical agroecosystem. Biodiversitas 20: 1880-1886. Cultivation of tomatoes on the middle-low plain generally decreases the quantity and quality of the yield due to high-temperature stress. Increasing the size and weight of lowland tomatoes is needed to enhance national production. Information on the action and genetic model of target characters is needed in the preparation of the assembly program, especially for selection needs. This study aims to obtain genetic information and heritability of tomato yield characters, as a basis for assembling large tomato varieties for the lowlands. The study was conducted using six populations (P1, P2, F1, BCP1, BCP2, and F2) resulting from two different crosses of 99D x Tora (C-I) and 97D x Tora (C-II). The results show that the action of non-additive genes and non-allelic interactions has a large value, with duplicate epistasis being more dominant than complementary epistasis. Duplicate epistasis was found in the character of harvest time, fruit length, fruit diameter, fruit weight in cross I and flowering time, harvest time, fruit length, fruit diameter, and number of fruits in cross II, while complementary epistasis was found in flowering time, fruit weight per plant, number of fruits in cross I, and fruit weight, fruit weight per plant in cross II. Moderate to high heritability was found in the character of fruit length, fruit diameter, fruit weight, and fruit weight per plant. The values are higher in population from the cross I (99D x Tora) for each character, indicating that the cross I has a higher potential for genetic progress than cross II. Selection is recommended when the homozygosity has increased, using the Bulk method or Single Seed Decent. The two methods above can maintain variability in the next generation, so epistasis genes that control target characters are not drastically eliminated.

Seventeen genotypes of bitter gourd (Momordica charantia L.) were studied in a field experiment conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka, during April 2009 to September 2010. The objectives of the study were to measure the variability among the genotypes for yield and yield contributing characters, estimate genetic parameters, association among the characters and their contribution to yield. There was a great deal of significant variation for all the characters among the genotypes. Considering genetic parameters high genotypic co-efficient of variation (GCV) was observed for branches per vine, yield per plant and number of fruit per plant whereas low genotypic co-efficient of variation (GCV) was observed for days to first male and female flowering. In all the cases, it was found that phenotypic co-efficient of variation was greater than genotypic co-efficient of variation. Highest genotypic and phenotypic co-efficient of variation was observed in branch per vine, fruit length, fruit weight and number of fruit plant which indicated a wide variability among the genotypes and offered better scope of selection. The results obtained showed that fruit length showed low direct and positive effect on yield per plant and indirect positive effect on yield per plant via fruit diameter and average fruit weight. Similar result was found for fruit diameter. Average fruit weight and number of fruits per plant showed high direct and positive effect on yield per plant. Path analysis revealed that average fruit weight, number of fruits per plant, days to male flowering and fruit length had positive direct effect on fruit yield. Considering group distance and the agronomic performance, the inter genotypic crosses between G2& G5; G2&G14; G14&G15; G2&G15; G10&G11; G10&G13; G11&G13; G5&G15; G5&G14 might be suitable choice for future hybridization programme.Bangladesh J.

The use of saline water is one of the major challenges of agriculture, as it can cause nutritional imbalances and thus reduce crop yield. This study proposes to examine the efficiency of potassium nutrition as a salt stress-mitigating agent in melon grown in a protected environment. The experiment was laid out in a randomized-block design with ten treatments in a 2 × 4 factorial arrangement represented by two melon cultivars (McLaren and SV1044MF) and four nutrient solutions (S1 - standard nutrient solution, 2.5 dS m-1; S2 - nutrient solution salinized with NaCl, 5.0 dS m-1; S3 - nutrient solution salinized with NaCl + 50% K, 6.5 dS m-1; and S4 - nutrient solution salinized with NaCl + 100% K, 7.5 dS m-1). Yield (average fruit weight, production, fruit diameter, internal cavity, and pulp thickness), quality (pulp firmness, total sugars, soluble solids [SS], vitamin C, pH, titratable acidity [TA] and SS/TA ratio) and nutritional (K, Na and K/Na ratio) variables were evaluated. Plants fertigated with standard nutrient solution showed the highest values for fruit weight (1,190.6 g), production (2,381.3 g per plant), fruit diameter (13.6 cm) and pulp thickness (2.6 cm). Cultivar McLaren produced heavier fruits (931.4 g) with larger diameter (12.4 cm) and pulp thickness (2.4 cm). The addition of NaCl to nutrient solution induced a reduction in the yield variables but did not influence fruit quality. The addition of extra K to salinized nutrient solution did not mitigate the deleterious effect of salinity on the yield of melon.
