Genotype X environment interactions for quality traits in mutants of Samba Mahsuri

摘要

Mutants of Samba Mahsuri differed significantly for all the quality characters. Environmental influence was noted for length / breadth ratio, amylose content and gel strength, while other characters were least influenced by environment. The variety Xenvironment interaction was significant for cooked kernel breadth, elongation ratio, amylose content and gel strength. The differences for protein content among mutants were not significant. Correlation studies revealed significant positive associationof 1000-grain weight with kernel length, volume expansion and amylose content. Raw kernel length exhibited positive significant association with cooked kernel and 1/b ratio. Raw kernel breadth was correlated with volume expansion and amylose content. Formany quality characters including amylose content, among the mutants, M-7 was found to be stable and retained quality characters of parent variety Samba Mahsuri. For amylose content, M-7, M-20, M-34, and M-72 were stable.
