CROSSOVER AND NON-CROSSOVER INTERACTIONS AND REGRESSION ANALYSIS FOR SEED YIELD AND OTHER TRAITS IN MACROSPERMA x MICROSPERMA DERIVED GENE POOL OF LENTIL

Abstract

Twenty nine advanced bold seeded macrospenna x microsperma derived lines of lentil alongwith check were evaluated in ten environments for six quantitative traits and data were subjected to regression analysis and also the analysis to detect the presence of crossover and non-crossover interactions. Four genotypes HPLC 8855, 8883, 8894 and 8895 were identified to be promising using regression analysis, whereas five genotypes HPLC 8829, 8887, 8888, 8892 and 8895 against standard check Vipasha were identified as potential ones by using crossover and non-crossover interactions concept. Of these genotypes, HPLC 8895 has been identified as high yielding genotype having specific adaptability and responsiveness to higher introgen regimes both by reg~ession analysis and crossover and non-crossover interactions concept.
