Description Two hundred genotypes with seven checks of Indian mustard were sown at two different interval (timely and late) in augmented block design for trait association and comparative phenotyping against heat stress at terminal stage. Correlation studies revealed that seed yield per plant had significant positive association with plant height, number of primary branches per plant, number of secondary branches per plant, leaf area index, total number of siliqua per plant, siliqua on main shoot and 1000- seed weight under both normal and late sown conditions. Based on results of heat screening parameters like heat susceptibility index, yield stability index and percent yield change, genotypes viz. NDRE-4, EC-399300, DRMR-13, DRMR-9, DRMR-7, DRMR-357, DRMR-6, EC-766423 and IM76 were found promising for terminal heat tolerance.
