영문 초록

Eight soybean plants which have 4-7 leaflets in a compound leaf, so called abnormal multileaflet soybean plants, could be obtained from the 2nd generations in four different soybean crosses, in 1977 and 1979. These multileaflet soybeans were multiplicated and used as the material in 1979 and 1980. Abnormal multi-leaflet plants were appeared very low frequency, i.e. 1 to 7500 plants in several cross combinations of soybeans. All of the plants which have abnormal multileaflets, 4-7 leaflets, could be recognized as the same type which have shown the recessive genotype. Abnormal multileaflet types consist of eight leaflet types, which are 2+2(2 lateral leaflets and 2 terminal leaflets), 2+3, 3+1, 3+2, 3+3, 4+1, 4+2 and 4+3 leaflet types instead of normal type 2+1 (2 lateral leaflets and 1 terminal leaflet). Those abnormal multi-leaflets were mixed in 61% with normal leaflets on one plant in average. Leaflets which had 2 lateral leaflets appeared more than those had 3 and 4 lateral leaflets, terminal leaflets which had 1 and 2 leaflets appeared more than those had 2 and 3 leaflets, and frequency of appearing tendency were should be concluded as 2+1＞ 3+1＞4+1＞2+2＞2+3＞3+3＞4+2＞4+3 leaflet types, respectively.
