Abstract

In context of climate change, yield potential of chickpea is hampered by heat stress. Increasing area of rice fallows, shifting in cropping system and global warming, needs to identify the chickpea genotypes tolerant to high temperature. With this objective an experiment was conducted during winter (rabi) season of 2020–21 at the seed breeding farm of Jawaharlal Nehru Krishi Vishwavidyalaya, Jabalpur, Madhya Pradesh in randomized complete block design (RCBD) with 3 replications. Forty two genotypes of chickpea were grown under timely (E I), late (E II) and very late planting (heat stress condition-E III). Selection of chickpea genotypes based on BYPP, HI and 100 SW will be more effective for constructing plant type suited to late sown conditions. On the basis of different heat indices, genotype JG 2020-27, JG 2020-32 in E I and E II and genotype JG 24, JG 2020-1, JG 2020-27 in E I and E III recorded higher YI, MP and GMP, respectively. Promising breeding lines recognized on the basis of various heat indices would be utilized in different chickpea improvement breeding programme in current changing climatic conditions.
