Abstract:
The production of green bean in Riau province is fluctuative, due to low interest of local people to grow this plant. One of the green bean varieties is from Kampar, it has small seed size, trichomes and no simultaneous harvest time. One of the efforts to improve the green bean phenotype and genotype is by making mutation using colchicine. This research aimed to test the stability of green bean characteristic (M1 and M2) to produce big size seed, simultaneous harvest time and no trichomes. The design used in this study was random assignment design with three treatments and nine replications. The agronomical parameters observed were the flowering times; the pod producing time; the 50%, 80%, 95% harvest time; the seed weight, the pod weight and number ; weight of 100 seed; the whole plants height, and the seed weight per hectare. Agronomical data were analyzed using SPSS 17,0. Based on agronomical observation, the best characters observed were the pod producing time, the 50% 95% harvest time, 100 seed weight and seed weight per hectare which is owned M2 plant.
