Heterosis, Inbreeding Depression and Line Performance in Crosses of Triticum aestivum

Abstract

Analysis of variance showed that the genotypic differences for these characters were highly significant. The phenomenon of heterosis and heterobeltiosis occurred in varying degrees in almost all crosses for the characters under study. Additive type of gene action and additive with the involvement of over-dominance type of gene action were present in almost all the traits. Inbreeding depression was exhibited to varying degree in almost all the crosses for yield and yield components.
