Abstract

•The high temperature treatments significantly reduced dry matter production and grain yield of mungbean genotypes.•Plants subjected to heat acclimation treatment prior to high temperature showed better performance than plants directly subjected to high temperature treatment.•Viable pollen number was directly related to pod number (r2=0.55**) and grain yield (r2=0.62**) on per plant basis.•Pollen viability and membrane integrity could be used rapid as tools to assess genetic variation in mungbean genotypes.•The study identified genotypes tolerant and susceptible to high temperature for further research.
