Abstract:

Cross - I exhibited high h2 coupled with moderate genetic advance as per cent of mean for Tw in all selection methods as well as different methods and date of sowing except in HY selection method on Ist date TP followed by LY selection methods on Ist date DS; and MTL selection methods on 2nd date TP indicating the preponderance of additive gene action as well as non-additive gene action. Cross – II and Cross – III were obtained highest average selection response for all the studied traits in HY followed by LY selection method. Among different methods of selection HY followed by LY selection method may be effective in early segregating generation for Cross – II as well as Cross – III whereas for Cross – I; LY followed by HY selection method may be more effective. It might be probable that delaying selection reduces the frequency of high yielding genotypes resulting in a greater frequency of low yielding genotypes.
