“…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.

Abstract. The norm of reaction in qualitative aspect was studied in 31 Bulgarian and foreign cotton cultivars. The results of competitive variety trial carried out at the Field Crops Institute in town of Chirpan during the period 2016 – 2019 were used. The type of their dynamic regression (of their regression curve) and the structure of ecological environments in their dynamic rows were determined, on five traits, in order to characterize the reaction norm of the studied genotypes. It was found that the studied cultivars had in most cases another reaction norm differing considerably from that of the standard variety. The specificity of their reaction was manifested to a smaller extent in regard to its type and more strongly in the structure of ecological environments in their dynamic rows. As regards the individual traits, the reaction norm of cultivars was expressed to varying degrees, depending on their peculiarities. In terms of type of reaction, cultivars 791-169 (similar to the standard variety in 4 characters), Philipopolis, Kris, Darmi, Natalia and T-08 (similar in 3 characters) were the closest to the standard variety. Cultivars Boyana, Nelina, Colorit and C-9070, in which there was no similarity of traits with the standard variety, and other 13 cultivars, similar in only one trait, were the furthest from it. Cultivars from these two groups could be included in one selection program to create new genotypes with a convex type of reaction for most of the traits. The convex type of regression, with the exception of Helius variety, occurred in all cultivars and traits, which was a prerequisite for an effective selection of genotypes with high adaptive ability. With high adaptability and very valuable for the cotton breeding programs were found the cultivars: IPTP Veno and Tabladila-16, with a convex type of dynamic regression in four traits – seed cotton yield, boll weight, fiber ginning out turn and fiber length; Kris, Stoneville 112 and Dorina with a convex type of regression for three traits.
