영문 초록

In order to obtain the basic information for the soybean mutation breeding, the seeds were treated with various gamma-ray doses of 10, 20, 30, 40, 50kR, and the response to different characters at seeding and harvest stage and mutation frequency using chlorophyll deficient mutation were investigated. Plant height, number of pods per plant and survival rate seemed to be appropriate characters to decide the radiosensitivity, and radiation doses of 20~30kR are recommended for mutation breeding. Chlorophyll deficient mutations were classified with xantha, chlorina, chlorotica and maculata types, and their frequency was 1.46 and 2.44% in M₂ plant basis at 20 and 30kR, respectively.
