Graphical Analysis of Spike Characters Related to Grain Yield In Bread Wheat (Triticum aestivum L.)

M. Kashif Riaz Khan and Abdus salam Khan

Abstract:
A 5 x 5 diallel cross experiment in wheat was conducted to investigate the mechanism of gene action controlling, inheritance of spike length, number of spikelets per spike, number of grains per spike, spike density and grain yield per plant. Highly significant differences were observed among genotypes for all the traits except grain yield per plant for which differences among genotypes were only significant. The graphical representation indicated the additive type of gene with partial dominance for all the characters studied. No epistatic effects were found for all the traits under considerable. From this discussion it could be concluded that selection for yield and its components would be effective in early genera from this material. The genotypes KLR-16 and 6544-6 would be the best promising lines to developed wheat varieties enhanced genetic potential.
