The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.
