Genetic architecture of yield and its Components in Bread Wheat (Triticum aestivum L. (

A half diallel cross consisting of six parents was used to study the genetic architecture of yield and its components in bread wheat. Randomized complete block design with four replications was used. Additive and nonadditive gene effects were detected on the studied traits. Desirable and significant heterosis, measured as departure of F1 from the respective mid- parent value, was observed for most hybrids.
