영문 초록

In order to investigate the frequency of chlorophyll and visible-macro mutations in M₂ population, the air-dried seeds were irradiated with 30kR of gamma-rays. The frequency of chlorophyll-deficient mutation of leaf was about 11% on M₁ plant basis and 1.8% in M₂ seedlings. The rate of visible-macro mutations, such as early and late flowering, shortness, erectoid, rosette, rugose, flower and pubscence color, leaf specks and yellowish-leaf type was about 15.430 and 3.7% on M1 and Ma plant basis, respectively, and the majority of visible macro-mutation types was shortness, early and late flowering, flower color, narrow leaf and rugose types. The mutation rate of two and three characters occurred coincidently in a M₂ plant was about 17.4 based on M₁ mutation plant. Segregation rate of mutants in M₂ averaged about 15% in chlorophyll mutations and 32% in visible-macro mutation types.
