Estimation of heterobeltiosis and character associations for yield and yield attributing traits in bread wheat (Triticum aestivum L.) genotypes

The study involves 29 parents and their 92 F1slaid out in RBD with three replications. ANNOVA for all the traits were found significantly variable at varying levels of significance. Highest heterobeltiosis of -10.22% for days to heading, 26.80% for grain yield and 25.46% for thousand grain weight were exhibited by BHU 31 × BHU 3, 6HPYT 416 × HUW 510 and HPVS 2 × BHU 3. Thus selection for these traits would be beneficial for indirect selection of grain yield. The crosses HPVS 1 × HUW 510, BHU 3 × BHU 6, 7HPAN 76 × BHU 3 and 6HPYT 407 × HD 3118 should be considered for the selection of homozygous lines in segregating generations with highest grain number per ear and biomass. | Estimation of heterobeltiosis and character associations for yield and yield attributing traits in bread wheat Triticum aestivum L. genotypes
