ABSTRACT

A 5x5 diallel cross involving five wheat varieties/lines (Kohistan-97, Chakwal-86, 6529-11, 6544-6 and 7086-1) was conducted. Twenty hybrids along with five parents were planted in randomized complete block design with three replications in order to find out the gene action controlling some vital polygenic yield related attributes like plant height, spike length, peduncle length, number of tillers per plant and grain yield per plant. Highly significant differences among genotypes were observed for all traits. Plant height has only significant differences. The graphical presentation demonstrated that number of tillers per plant was ruled by partial dominance with additive type of gene action. While over-dominance was observed in plant height, spike length, peduncle length and grain yield per plant. It showed the potential for the availability of transgressive segregates in later filial generations. The prevalence of partial dominance type of gene action for number of tillers per plant showed that it can be gradually improved by selection.
