Genetic Divergence for Grain Yield and Its Components in Bread Wheat (Triticum aestivum L.): Experimental Investigation

The present investigation Comprises 34 advanced breeding lines including checks of bread wheat and experiment was conducted in a complete randomized block design with three replications at the research farm department genetics plant breeding, RVSKVV, B.M. College Agriculture, Khandwa during Rabi season (November 2021 to April 2022) for estimation multivariate analysis divergence. were grouped into seven clusters. Cluster III contained highest number lines(12) clusters V, VI, VII lowest (1 each). inter-cluster distance most cases larger than intra cluster which indicated that wider diversity is among distant grouped. observed IV revealed maximum genetic divergence its constituents. found between VI V VI. Highest mean exhibited agro-morphological traits i.e. tillers/plant, spike length, weight, grain/spike followed by II grain filling period, days maturity height. On basis analysis, percent contribution towards maturity, grain/spike, 50% flowering, biological yield per harvest index. Such differences component studied manuscript can be applied as source variation other programmes crossing nurseries improvement.
