Genetic Evaluation of Spring Wheat (Triticum aestivum L.) Recombinant Inbred Lines for Spot Blotch (Bipolaris Sorokiniana) Resistance and Yield Components under Natural Conditions for South Asia

The objectives of the present study were to evaluate spring wheat recombinant inbred lines (RILs) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (PCA) for spot blotch resistance and yield components at BHU Agricultural Research Farm during 2010-2011. Grain yield per plot was significantly and positively associated with biomass, 1,000-grain weight,...
