영문 초록

In M₂ generation of barley treated with radiation, mutation frequency, segregation pattern, radiation damage and mutation rate, and sector size were investigated. Frequency of chlorophyll mutation with albina and xantha type was 8.8% in Mz family and 0.89% in M₂ plant basis. Chlorophyll mutations in M₂ seedling were segregated with fit type to 3:1, recessive excessive and unidentified type. Mutation rate of albina was higher with increase of number of seeds per M₁ spike and in xantha type no tendency was found between mutation rate and seed numbers per M₁ spike. Sector size in mutated plant with albina was average 14. 1% and 6.0% in xantha type.
