Description Plant genetic diversity provides opportunity toplant breeders for improving the plant characteristics andhelps to tackle the threats of biotic and abiotic stresses.Therefore, present study was envisioned to evaluate thegenetic diversity in F4 and F5rust- resistant derived progeniesof two crosses of bread wheat i.e., WH 1105 × WH 711 andRaj 3765 × WH 711 for grain yield plant-1 and related traits.Moderate to high values of genotypic and phenotypiccoefficients of variation were observed for grain weight ear-1,grain yield plant-1, biological yieldplant-1,etc. High heritabilitywith high genetic advance were observed for number oftillers plant-1, grain weight ear-1, 100-grain weight and grainyield plant-1 indicating predominance of additive gene effectsand possibilities of simple selection. Based on D2 Statistics, thegenotypes were distributed into five to six clusters where thehighest inter-cluster distances were found between cluster Iand V (27.34) in F4 generation, I and IV (24.38) in F5 generationof cross-I, I and VI (26.53) in F4 generation and III and IV(25.16) in F5 generation of cross-II indicating wider geneticdiversity among these clusters. Traits namely, number ofgrains ear-1, grain weight ear-1, number of tillers plant-1 andnumber of spikelets ear-1 showed highest contribution (morethan 60%) towards genetic divergence. Hence, consideringthe magnitude of genetic distances, contribution of differenttraits towards total divergence and magnitude of clustermeans for different traits, the genotypes belonging todiverseclusterscould deliver maximum heterosis and goodrecombinants with desired traits in varietal improvementprograms
