To study crossover and non-crossover interactions for three phenological traits of twenty nine advanced bold seeded recombinant lines, selected from macrosperma x microsperma crosses, against the similar triats of check Vipasha, the experiment was conducted in the ten environments of the hills of Western Himalayas. Six genotypes for days to 50% flowering, nineteen genotypes for days to maturity and nine genotypes for duration of reproductive phase exhibited crossover interaction. The presence or absence of crossover interaction was genotype specific and trait specific.
