Abstract: In order to explore the genetic characteristics of mungbean growth stages, the RIL population consisting of 261 strains constructed using ‘VC2917’ (an early maturing local variety) as the female parent (P1) and ‘Pinker Green’(a late maturing local variety) as the male parent (P2) were used as materials for the investigation of traits and heritability analysis in the flowering and maturity periods of the population under four ecological conditions. The results showed that, under the four ecological conditions, the flowering period of P1 and P2 were 53.8 d and 41.0 d, respectively. The average flowering period of 261 strains was 47.4 d, the maximum was 61.8 d, and the minimum was 35.3 d. The maturity periods of the P1 and P2 were 83.1 d and 56.3 d, respectively. The average maturity period of  population was 72.3 d, the maximum was 90.0 d, and the minimum was 48.8 d. The flowering and maturity period of  RIL population were both normal distribution. There was significant difference of flowering and maturity periods between two parents and RIL population. The broad-sense heritability of the flowering and maturity period was 0.955 and 0.954, respectively. It was illustrated that the flowering and maturity period of mungbean were both quantitative traits controlled by major genes.
