An experiment was conducted to access the genetic variability among early vigour and quantitative traitsunder limited moisture in F2 generation of a 5 x 5 diallel cross of bread wbeat.The results indicated that there wassignificant genotypic variation among the genotypes.Additive dominance model revealed full fitness of the data for RL,DSW,FRW,DRW,spike length,and lOOO-grain weight but was partially fit for SL,FSW,R/S,tillers per seedling,plantheight tillers per plant,spikelets per spike,and grain yield per plant.The partially adequate models for these plantcharacters might be due to the presence of non-allelic interaction,linkage,and non-independent distribution of thegenes in the parents.Additive genes coupled with moderate to high narrow sense heritability were involved in theheritage of all the traits,which indicated a higher scope of selection in early generations.
