Heterosis for Seed Fibre Quality Traits Cotton (Gossypium hirsutum L. )
Author(s): Rani Chapara and Sudharani Madugula*
Study of heterosis is very crucial to identify the promising hybrid combinations for further advancement of the
material and also to exploit as such for commercial cultivation of hybrids. The objective of this research was to
estimate the heterosis of all types i.e. mid parantal heterosis, heterobeltoisis and standard heterosis for fibre quality
parameters. Nine genotypes and 20 F1 hybrids derived by crossing the parental genotypes in L × T design were sown
in randomized complete block design along with standard check Suvin. It was observed that the line × tester
interactions made greater contribution to the total variance for all the fibre quality traits studied. Proportional
contribution of lines to total variance was very low for all the traits, while testers also followed similar pattern and
contributed a minimum to the total variance. Howev.. Read More»
