Abstract:
Central zone usually faces terminal heat stress at the time of grain filling under late planting conditions hence, the present experimentation were conducted on 30 genotypes in randomized block design with three replications under terminal heat stressed condition. The analysis variance showed significant difference for all the studied traits. The high value of PCV and GCV were observed for harvest index and yield plant-1. The high heritability coupled with high genetic advance were observed for most of the studied traits viz; harvest index (%), yield plant-1 (g), number of leafs plant-1, biological yield plant-1 (g), peduncle length (cm), wet gluten (%), SDS (mm) and 1000 grain weight (g). Correlation coefficient revealed that the grain yield per plant exhibited highest significant positive association both at genotypic and phenotypic level with harvest index (%), biological yield plant-1 (g), number of leaves plant-1and significant negative association with moisture (%), protein (%) and starch (%) and 1000 grain weight (g).Path analysis showed that highest positive direct effect on grain yield were exerted by harvest index, biological yield plant-1 and number of leafs per plant whereas highest negative direct effect were exhibited by 1000 grain weight, protein % and canopy temperature. Under stressed conditions these traits were important for any selection programme and quality analysis will help to find out those traits which will improve at the cost of yield.
