Twenty nine advanced bold seeded macrosperma x microsperma derived lines of lentil along with check were evaluated in ten environments for six quantitative traits and data were subjected to detect of crossover and non-crossover interactions. Sixteen genotypes for plant height, eight genotypes for branches/plant, thirteen genotypes for fertile nodes/plant, fifteen genotypes for pods/plant, nineteen genotypes for pods/node and three genotypes for seeds per pod exhibited crossover interaction against their corresponding traits of check Vipasha, The presence or absence of crossover interaction was genotype specific and trait specific.
