 ABSTRACT

In order to study the gene effects for grain yield and other component traits of cross WH1105 X WH711 of wheat (Triticum aestivum L. em. Thell) five generations i.e. parents (P1 and P2), F1, F2 and F3 were studied using generation mean analysis. The C-scaling test was significant for all the characters indicating thereby the presence of non-allelic interactions. Generation mean analysis revealed significant differences for all traits studied. Additive gene effects was significant for most of the characters and higher in magnitude over the dominance gene effects. Additive x additive (i) and dominant x dominant (l) type of interaction have been significant for most of the characters. Duplicate epistasis was recorded for number of tillers per plant, grain yield per plant and biological yield/plant.

Key words: C-scaling test, gene effects, generation mean analysis, wheat (Triticum aestivum L. em. Thell)
