“…The estimate of GCA and SCA variances was presented in table 1. The results are in concordance with the finding of Punitha and Raveendran (1999), Saravanan et al, (2010), Shinde et al, (2018) Swetha et al (2018 and Chinchane et al (2018) for yield and quality characters. The per se performance was considered as the first important selection index in the choice of parents and the selection of suitable parents with high per se performance will result in superior hybrids (Gilbert, 1958).…”

Line x tester analysis was carried out involving six lines and 4 testers for seed cotton yield, yield contributing traits and fibre quality traits for estimation of combining ability effects of parents for sixteen characters. The analysis of combining ability revealed that the variance for SCA were larger than GCA except uniformity ratio which corresponds with nonadditive gene action which can be improved by heterosis breeding. Based on the high per se performance and high gca effect, the parents C 10-8 and RAHC 1917 were considered as best general combiner for boll weight and single plant yield per plant. Regarding boll weight, TCH 1822 and C 10-8 were good general combiners with significantly high per se performance. These parents were found to be recorded as good general combiners for different characters. Hence, these can be used in recombination breeding to obtain more favorable gene recombinations for seed cotton yield. The cross TCH 1819 x RS 2821 showed a positive and significant sca effect for the number of bolls, boll weight and seed cotton yield. The cross Anjali x CPD 1501 showed a positive and significant sca effect for boll weight, lint index, seed index and seed cotton yield. The cross TCH 1926 x RS 2821 exhibited a positive significant sca for the number of bolls, 2.5 % span length and fibre strength. The non -additive gene action has played an important role in expression of seed cotton yield and its component traits which justify the heterosis breeding and its exploitation commercially.

“…This indicated that the environments created by various sowing dates were justified had mostly linear effect. These results are in agreement with the earlier findings of Tuteja et al (2006), Balakrishna et al (2016), Vanisri et al (2016), Jamwal et al (2016, Chinchane et al (2018) and Pinki et al (2018).…”

A line x tester analysis using 10 lines and five testers were carried out to study the stability of 50 hybrids over environments using three different sowing dates for seed cotton yield and its quantitative traits in cotton. The analysis of variance for stability revealed significant differences among the genotypes for all the characters when tested against the pooled error and pooled deviation. The mean square due to environments (E) was also found significant when tested against the pooled error and pooled deviation for all the characters. G x E interactions were non-significant for all the characters except days to 50% flowering, days to 50% boll bursting, seed index and oil content indicating linear response of different genotypes for various traits under varied environmental conditions. The variance due to environments (linear) was significant for all the traits when tested against pooled error as well as pooled deviation. The stability parameters viz., overall mean (X ̅ ), regression coefficient (bi) and deviation from regression (S 2 di) revealed that the hybrids G.Cot 18 x GSHV 173, G.Cot 18 x GTHV 7/70, G.Cot 12 x GTHV 7/70, G.Cot 12 x G.Cot 20 and GJHV 511 x GSHV 173 were the most widely adapted and stable crosses for seed cotton yield per plant and its components.

“…In present studies, it was also concluded that high × high, high × low and low × high general combiners performed better in manifestation of specific F 1 hybrids for yield and lint traits. Previous studies also revealed that for getting good cross combination, at least one of the parents should have good GCA effect i.e., high × high, high × low and low × high GCA parents in cotton (Chinchane et al 2018). In past studies, in some cases high × low, low × high and high × high GCA parents showed best performance for majority traits in upland cotton (Panhwar et al 2008;Khan et al 2011Khan et al , 2015Karademir et al 2016).…”

Line × Tester combining ability analysis involving five lines (cultivars i.e., CIM-446, CIM-473, CIM-506, CIM-554 and SLH-284) and three testers (cultivars viz., CIM-496, CIM-499 and CIM-707) was carried out during 2015 and 2016 to determine the inheritance for earliness, yield and lint traits in upland cotton. Genotypes revealed significant (P≤0.01) variations for all the traits. On average, F 1 hybrids showed the significant increase over parental means for yield traits. Mean squares due to general (GCA) and specific combining ability (SCA) were highly significant, which suggested that additive and non-additive gene actions were involved in controlling all the characters. However, the preponderance of non-additive type of gene action observed for majority of the traits. Lines (SLH-284, CIM-473) and pollinators (CIM-707, CIM-496) were leading general combiners for majority of the traits. F 1 hybrids (CIM-473 × CIM-496, SLH-284 × CIM-707 and CIM-446 × CIM-496) which involve best general combiners, showed the leading performance for yield and lint traits. Heritability was moderate to high with appreciable genetic gain for majority of the traits. Except for lint %, the correlation of seed cotton yield was positive with other traits. The significance of additive and non-additive components suggested integrated breeding strategies with delayed selection for development of cotton hybrids with improvement in earliness and seed cotton yield.
