Weighted average absolute scores of BLUPs (WAASB) based selection of stable Asiatic cotton genotypes for the salt affected Vertisols of India

Cotton is a major cash crop classified as moderately tolerant to salt stress (threshold ECe = 7.7 dS m-1). In the present study, set of 21 homozygous advanced breeding lines cotton (Gossypium herbaceum L.), including one variety G Cot 23 was evaluated over three years identify stable high yielding genotypes under stress. Weighted Average Absolute Scores BLUPs (WAASB) stability index, which based on single value decomposition BLUP, employed for this purpose. Among genotypes, CSC-025 and CSC-057 showed highest boll weight (59.67 57.33 g/20 boll), seed yield (1818 1570 Kg ha-1) leaf K/Na ratio (9.6 5.6) check 23. Considering both WAASB index mean trait values, CSC-025, were found promising all traits can be considered deployment in salt-affected Vertisols India.
