Description:
Two grams of AG-S4 seed was irradiated with 20 kR of gamma radiation. A random 1200-plant population (AG-S4-IR) was grown from irradiated seeds under greenhouse conditions. After self-pollination, seeds from two pods per plant were collected and designated IR-S1. A second random 1200-plant population was grown from the IR-S1. A single rapid flowering clone was identified (RG-S1). Seeds of RG-S1 were germinated to produce 28 RG-S2 plants whose composite populations of seeds (RG-S3) is AG-S4
