The short harvest period is one of the major focuses of mungbean breeding programs. Improvement of harvesting period can be reached by recombination among the best parents. The objectives of this research were to study performance, genetic inheritances, identified and to select of transgression segregants for short harvest period in F2 (Lombok x No.129) population. This research was conducted in Leuwikopo-IPB Farm, Bogor, Indonesia, from March to July 2019. The genetic materials were F2 (538 plants), Lombok/P1 (40 plants), No.129/P2 (40 plants) and F1 (40 plants). The results showed that the mean values of the F2 population were early than parents for plant age traits, respectively days to first pods maturity, days to 90% pods maturity, and harvesting period. Seed weight and the number of pods characters increased from parent mean values. Harvesting period was dominated by genetic (h 2 bs >55%) with wide genetic diversity, and controlled by additive-duplicate epistatic gene action with many genes (polygenic) involved. Transgressive segregation for harvest period divided into 84 plants as short that harvested less than 14 days, 258 plants as medium (14-28 days), and 196 plants as long (>28 days). Short harvest period selection gives out high genetic advance (20.759%).
