Greengram (Vigna radiata) is one of an important pulse crop grown as pre-rabi, rabi and summer crop in Odisha. During rabi season, the cold stress affect this crop and reduce its productivity. The genotypes with little winter hardiness will be beneficial to the agroclimatic zone having rabi temperature around 150 C. Therefore a study was under taken on twenty one genotypes along with nine check varieties in both laboratory and field condition at different location during the winter season. The genotypes OBGG-2013-9 and OBGG-2013-14 found best cold tolerant lines and can be used as donor for cold tolerance breeding. The genotype OBGG-2013-34 was the highest yielder genotype having medium tolerance to cold with moderate susceptibility reaction to MYMV and produced 23% more than the best check variety (TARM-1) followed by OBGG-2013-20 and OBGG-2013-11 which showed resistant to MYMV but lack of cold tolerance ability. The genotype OBGG-2013-8 was superior in cold tolerance as well as MYMV resistance but low yield than the best check. Thus hybridization between OBGG-2013-34 and OBGG-2013-20 or OBGG-2013-11 was expected to produce superior genotype combining gene for cold tolerance and MYMV resistance with higher yield potential. These cold tolerance genotypes will be more beneficial to eastern part of India where greengram crop is grown during rabi season in rice fallow cropping system and very useful to eco-geographical area where winter is little late.
