A field experiment was conducted at College farm, Agricultural College, Bapatla, Acharya N.G. Ranga Agricultural University during summer, 2022 and 2023 to study the influence of high temperature stress on morpho-physiological and yield traits of blackgram genotypes. The experiment was carried out in randomized block design with 30 treatments and 2 replications. The study revealed that among the thirty blackgram genotypes screened for their tolerance to high temperature stress at flowering stage, the genotype, TBG-129, LBG-1015 and PU-1804 were found to withstand high temperature stress and maintain higher SPAD chlorophyll content, and higher seed yield per plant indicating tolerance to high temperature stress during both the years. These blackgram genotypes can be further used as donors in the pulse breeding program for development of heat resilient varieties.

Keywords: Blackgram, high temperature stress, flowering stage
