Biometrical characteristics of R2 generation of anther-derived pepper (Capsicum spp.) plants

Eight anther-derived DH lines of pepper hybrids: two red-fruited (AP14, AP15) and two yellow lines (AP25 and AP32) of C. annuum (ATZ1 × PO)F2, two lines of (C. frutescens × C. annuum)F1 (FA1, FA2), and two of (C. frutescens × C. chinense)F1 (FCH2, FCH3), were studied regarding important morphological plant and fruit characters. C. annuum breeding line 'ATZ1' was used as a standard. The following traits were evaluated: total fruit yield, fruit weight, weight of placenta with seeds, technological matter, pericarp thickness, extract content, dry matter content, weight and number of seeds per fruit. The level of homogeneity within the DH lines was analysed with a one-way analysis of variance, additionally the values of coefficient of variation (CV) were determined for the tested plant characters. The highest phenotypic uniformity was noted for the red-fruited lines obtained from anthers of (ATZ1 × PO)F2 and for the DH lines of (C. frutescens × C. annuum) F1, while the least uniform were FCH2 and FCH3 lines of (C. frutescens × C. chinense)F1. The DH lines AP14 and AP15, as well as FA1 and FA2 were phenotype homogeneous in respect of weight of fruit, technological matter, pericarp thickness and extract content. For these parameters, also the values of CV were the lowest. Statistically significant interline polymorphism between the androgenic lines of the same origin was detected among the lines of C. annuum (ATZ1 × PO)F2.

The experiment was conducted during rabi season, 2003-2004 at the Field Laboratory of the Department of Genetics and Plant Breeding, Bangladesh Agricultural University, Mymensingh. Genotypic variability, heritability and genetic advance for yield and yield contributing characters were studied on 55 tomato genotypes. Data were recorded on number of primary branches per plant, days to first flowering, plant height, number of bunches per plant, number of fruits per plant, individual fruit weight, number of seeds per fruit, dry matter content of fruits, pH level of fruit juice and yield per plant. Very little differences were observed between genotypic coefficient of variation and phenotypic coefficient of variation for all the characters except dry matter content and yield per plant indicating that they were less influenced to environmental factors for their phenotypic expression. High heritability estimates coupled with high genetic advance in percentage of mean were obtained for number of primary branches per plant, number of days to first flowering, plant height, number of bunches per plant, number of fruits per plant, individual fruit weight and number of seeds per fruit indicating wide scope for improvement through selection of these traits.DOI: http://dx.doi.org/10.3329/pa.v19i1.16982 Progress.

Biometrical Assessment of Interspecific Hybrids ofCapsicumGenusThe F1hybrids obtained as the result of interspecific crosses:C. annuumxC. frutescens, C. frutescensxC. annuum, C. frutescensxC. chinenseandC. chinensexC. frutescenswere analysed biometrically. The plants were cultured in unheated foil tent. Yield and the number of fruit from plant were qualified. For ten plants of each of the hybrids detailed fruit analysis were performed. The tested traits were: weight of fruit, length, width, technological weight and weight of pericarp, pericarp thickness, the weight of placenta without seeds, the weight of dry seeds and the dry matter content. The analysis of variance was conducted on the obtained results. The tested hybrids were characterised by the large differentiation of the estimated characters. The hybrids obtained from crosses:C. annuumxC. frutescensandC. frutescensxC. annuumseem to be the most valuable material for the future pepper breeding work. Fruits of these hybrids combine high weight, typical for cultivated forms ofC. annuumwith increased dry matter content characteristic forC. frutescens. These materials will be used as the parental forms of homozygous lines which possess traits valuable in genetic improvement of pepper.

This study aimed to evaluate 69 Capsicum accessions from the Germplasm Bank of Universidade Federal de Roraima, for some fruit quality traits. The experiment was performed in a completely random design, with 69 treatments and 3 replications. The 69 accessions were evaluated for fourteen quantitative and two qualitative traits of ripe fruits. Quantitative fruits data were subjected to an analysis of variance, and the means were grouped by Scott-Knott test (p<0.01). All characteristics had significant effect of treatments (p<0.01) for all evaluated traits. The data showed high genetic variability to future use in a Capsicum breeding program. The accessions 33, 44 and 41 showed major values for dry matter content and total soluble solids; these should be used to improve these traits in a paprika breeding program. On the other hand, the accession 48 showed major values for fresh weight, major fruit length and fruit width. The accession 33, belonging to the Capsicum frutescens species, with high vitamin C content should be used in a fresh market Capsicum breeding program.

The purpose of this study was to practice and improve the use of low volume crowns in a high-density system in order to obtain qualitative cherry production that would be competitive on the market and to make efficient use of the labor force. The research was carried out in the intensive cherry orchard planted in the autumn of 2011 with “Ferrovia”, “Kordia”, and “Regina” varieties, grafted on Gisela 6 (Prunus cerasus × Prunus canescens) rootstock interspaced at 4x2.5 m and managed according to the Ameliorated natural crown systems with low volume, Ameliorated Slender Spindle and Vase shaped crown. Harvest, diameter, firmness, dry matter content and fruit weight were determined. The trees started to yield in the third year after planting. The harvest in the second year of yielding was 4-5 kg/tree. The average harvest in the third year of yielding was 9640-13290 kg/ha. For all three varieties the harvested quantity and fruit size were correlated with the crown shape. The Ameliorated Slender Spindle crown provided the highest production per hectare, while the Flattened Vase Shaped crown provided the lowest yield but had the highest values of the fruit size (28.2-28.4 mm) and of the soluble dry matter in the fruit (17.9-18.6 Brix%).

Pepper fruits (Capsicum annum L. c.v. Caribbean) were treated with two commercial was coatings, Primafresh and Prolong. Fruits were sprayed with Primafresh (original concentration) and Prolong at 0.5% and 1.5% (w/v) concentration. Fruit samples were taken for analysis each of 5 days during 20 days from storage rooms at 1, 5, 10, and 15C. Parameters TSS, titratable acidity, pH, fresh fruit weight loss, texture, and dry matter content were analyzed. TSS and dry matter decreased with the storage time. Titratable acidity increased until 10 days after storage and decreased when fruit were stored for a longer time. The lowest texture deformation was observed at 1 and 5C. Coating treatments reduced the rate of fresh fruit weight loss of peppers compared to uncoated ones.

Ripening Time

Ripening time of peach cultivars that are grown up in our country is extended over a time period of almost four months. In addition to that, one of more important objectives of the peach breeding is creation of the cultivars having either very early or very late ripening time. Our so far experience is that the peach cultivars which ripening time is in the extremes is of lower fruit quality. The aim of this study, therefore, was to determine relationship and the nature of the dependence between flowering time or ripening time from one side and yield, yield components (initial and final fruit set, fruit weight and stone weight) and chemical composition of fruit (content of total dry matter, content of soluble solids, content of total, invert and reduced sugar and content of total acid) on the other side. Twenty peach cultivars each having a different ripening time were using as material. The relationship between characteristics was determined on the basis of values of genetic and phenotypic correlation coefficients. Genetic and phenotypic coefficients of correlation were calculated based on the results of monofactorial analysis of covariance where the years considered as replications. It was confirmed that flowering time was positive genetic and phenotypic correlated with initial fruit set and with final fruit set. The existence of significant genetic and phenotypic correlation between ripening time and fruit weight, between ripening time and dry matter content and between ripening time and soluble solid content represented difficulty in creation of new peach cultivars of early ripening time and improved fruit quality .

Background. The main trend in melon breeding is the development of cultivars with good taste, high yield, and disease resistance. The task may be solved through a scientific search for new source material meeting these requirements.Materials and methods. The research was performed at Bykovsky Cucurbit Breeding Experiment Station. Melon accessions of various origin and F1 hybrids from the nursery of source material served as the research material. In total, during the period of 2015–2017, over 100 melon accessions were studied: 45 accessions from the VIR collection, 61 from various companies, and 12 developed at various research institutions. In the nursery of source material, the accessions were hybridized and the resulting hybrid combinations were tested, including tests against infections. All of them were evaluated for their economically useful traits, yield, taste qualities, and resistance to bio- and abiostressors. During the trials they were compared with the best released cultivars approved for dryland conditions according to the developed guidelines.Results. The purpose of this work was to study the genetic collections of melons and obtain new source forms for further breeding. As a result of the study of the collection material, 12 accessions were identified with the following economically useful traits: high yield (exceeding the reference by more than 20%), high dry matter content (from 14 to 19%), large fruit size (fruit weight higher than 4.0 kg), and other features. After hybridization and testing in F1, the following 5 hybrid combinations were distinguished: Ekler × Osen; Dyuna × Mayskaya, Sheker and No 323; Katyusha × Mestny (k-7459, Georgia); Harmony × Mestny (k7461, Georgia), characterized by a set of features important for breeding.Conclusion. Thus, for further improvement by breeding and release of new melon cultivars, source accessions were selected with a yield exceeding 15.0 t/ha, dry matter content of 13.0%, bright fruit color, and resistance to diseases.

Nutritional Characteristics

This study evaluated the nutritional characteristics of hay of nineteen hybrids between sorghum and Sudan grass. The experimental design was a randomized block with nineteen treatments and three replications. The chemical characteristics of the respective hays were analyzed 52 days after sowing and 45 and 49 regrowth days. Data were analyzed by analysis of variance, and when the F test was significant, the treatment means were compared by the Scott and Knott test at 5%. Genotypes 1013026 and 1014020 showed similar dry matter content. As for ether extract content, the highest values ranged from 2.20 to 2.66%. Higher values of minerals were observed in hybrids 1013026 and 1011005. In relation to crude protein, higher content values were reported for hybrids 1013021 and 1013020 (14.59 and 15.47% CP). When evaluating the neutral detergent fiber content, lower values varied between 56.05 and 57.07% for hybrids 1013016 and 1011009. Considering the content of acid detergent fiber, values ranged from 32.70 to 35.78%. Values of dry matter digestibility were higher than 50%. All hybrids provide quality hay, however the hybrid 1014019 showed the best nutritional value.

Vegetative Organs

The dry matter and moisture contents of the aboveground vegetative organs and kernels of four maize hybrids were studied in Martonvásár at five harvest dates, with four replications per hybrid. The dry matter yield per hectare of the kernels and other plant organs were investigated in order to obtain data on the optimum date of harvest for the purposes of biogas and silage production.It was found that the dry mass of the aboveground vegetative organs, both individually and in total, did not increase after silking. During the last third of the ripening period, however, a significant reduction in the dry matter content was sometimes observed as a function of the length of the vegetation period. The data suggest that, with the exception of extreme weather conditions or an extremely long vegetation period, the maximum dry matter yield could be expected to range from 22–42%, depending on the vegetation period of the variety. The harvest date should be chosen to give a kernel moisture content of above 35% for biogas production and below 35% for silage production. In this phenophase most varieties mature when the stalks are still green, so it is unlikely that transport costs can be reduced by waiting for the vegetative mass to dry.
