Background: Among several reasons for low productivity in mungbean, various biotic and abiotic factors play a major role. Although intensive research work has been done on genetic architecture of yield and yield attributes of mungbean but limited work was done on yield attributes along with water use efficiency (WUE) and heat stress tolerance related traits. The present study is aimed to identify the genetic potential of mungbean genotypes with high yield and drought and heat stress tolerance.Methods: The F2 seed was harvested from selfed F1 population during 2017-18 from three superior crosses viz., ML 267×LGG 528, MGG 390×LM 95 and LM 95×EC 362096. These crosses were selected based on their per se performance of yield, yield attributes and WUE related traits. Genetic analysis was carried out in F2 populations of three crosses for fourteen quantitative characters to identify the number of transgressive segregants in desirable direction.Result: A good number of transgressive segregants in desirable direction were observed for plant height, number of pods per cluster, harvest index, SLA, SLW and relative injury in the cross ML 267×LGG 528: for plant height, number of branches per plant, SCMR, SLA, SLW and relative injury in the cross MGG 390×LM 95 and for plant height, number of pods per cluster, number of pods per plant SCMR, SLA, SLW, relative injury and seed yield in the cross LM 95×EC 362096.
