“…The GCA and SCA effects and their interaction with location was also significant depicting different reactions by different genotypes to the environmental influences. This indicates possible deviations in performances of varieties/hybrids in different environments.Previous studies in different crops (Nass et al, 2000;Golkar et al, 2017;Murtadha et al, 2018;da Rocha et al, 2018;Ferriera et al, 2018;Moura et al, 2018;Yu et al, 2020) also reported significant interaction of environment with GCA and SCA indicating varying estimates of GCA and SCA in different environments. Significant interaction of GCA and SCA with environment suggests selecting different parental lines for hybrids for specific environments.…”

“…This scheme provides opportunity for wide recombination of favorable alleles from different parents, and thereby increases the likelihood of the occurrence of superior genotypes (Ferreira et al, 2018) In general, combining abilities are estimated by evaluating hybrids along with parents in a particular location or year. However, the estimates of combining ability are affected by environmental influences (Ramalho et al, 1988;Nass et al, 2000;Pswarayi and Vivek, 2008;da Rocha et al, 2018) and hold relevance to the particular environment. Consequently, the hybrids so developed, may not perform well acros diverse environments (Senguttuvel et al, 2021).…”

The multilocational studies were conducted to evaluate 21 hybrids of tomato in Pratapgarh(Uttar Pradesh), Varanasi (Uttar Pradesh) and Burdwan (West Bengal), India during August–February of 2015–16 and 2016–17. Data on four quality traits viz., total soluble solids, titrable acidity, carotene content and lycopene content were estimated. Combined analysis of variance (ANOVA) revealed significant effects of locations, genotypes, genotype-location interaction and parents vs hybrids-location interaction for all the traits. The significance of combining ability effects (general combining ability and specific combining ability) and their interaction with location revealed environmental influences on combining ability effects for all the traits. The Present study indicated higher estimates of to , lower estimates of heritability and GCA/SCA ratio for quality traitsandthereby implied preponderance of non-additive gene action in determination of quality traits studied. Desirable parental lines were identified for different traits like EC 620438 and BS 24-2 for TSS, BS 24-2 and Superbug for titrable acidity, Columbia, EC 620438 and Superbug for carotene content, and H 86 and EC 620541 for lycopene content. Similarly, desirable specific combiners for different traits were identified. The hybrid combination EC 620438×BS 24-2 appeared good specific combiner for TSS, carotene and lycopene content. The parental lines/hybrids identified in present study will be useful in identifying hybrids adapted to a range of environments.

“…Diallel mating designs are often used when a series of lines are part of a breeding program and superior combinations have to be identified (Hallauer et al 2010, Rocha et al 2018). This methodology is already being applied to several species (Bignotto et al 2015, Barata et al 2019) and has been described for tobacco in temperate climate.…”

This study estimated the general and specific combining abilities and mean heterosis of tobacco lines of the varietal groups Flue-Cured Virginia (FCV) and Air-Cured Burley (BY). In addition, possible advantages and an improved strategy of using hybrids in tobacco breeding in the tropics were discussed. Ten BY and 13 FCV lines were crossed in a diallel mating design. The hybrids and parental lines were evaluated at two locations in Southern Brazil. The mean heterosis was 5.37% for FCV and zero for BY lines, although higher than 15% in some combinations. The occurrence of heterosis indicates dominance in the control of tobacco yield. Tobacco breeding programs must focus primarily on improving the performance of lines per se and then on the identification of the best hybrid by testing combinations.

“…At the same time, this plant has a high photosynthetic efficiency and can form a powerful biomass in a short time. Due to its biological characteristics, it is an alternative source of biofuels and sugar-containing products based on the processing of sugar sorghum stems [3][4][5]. Therefore, the creation of new highly productive varieties and hybrids of sorghum intended for use as an alternative raw material in the production of bioethanol is a promising direction in breeding.…”

Combinational ability of crossing components and heterosis of F1 hybrids of sugar sorghum by biomass yield

et al. 2021

Currently, the most promising direction of breeding is the creation of F1 hybrids of sugar sorghum, based on the identification and selection of parental forms with high combinational ability. The source material and F1 hybrids were grown in the arid conditions of the Saratov Right Bank (Russia): the hydrothermal coefficient during the growing season was 0.68. The evaluation of the combinational ability of crossing components was carried out using the topcross method. As a result of the tests, the L-52/13 line was identified with high GCA effects (15.71), and the highest SCA dispersions were found in the Saratovskoe 90 variety and the L-39/12 line (91.80-189.27). It was found that the type of sterile cytoplasm of iso-nuclear CMS-lines had a significant impact on the manifestation of SCA in terms of biomass yield: higher dispersion indicators were noted in 9E Zheltozernoye 10 (36.66). Genes with an additive effect are involved in the genetic control of this trait in paternal forms, and non-additive genes in maternal forms. In addition, each hybrid combinationwas observed with superdomination: the coefficient of phenotypic dominance varied from 2.01 to 18.91. It is advisable to use the obtained information in the hybridization of sugar sorghum to obtain high-heterosis hybrids.
