摘要

Research on application of the induced mutation method combined with crossingin soybean breeding for 20 years 1980-2000) plays an important role in research work at AGI, (Minsitry of Agriculture and Rural Development of Vietnam). 23 soybean varieties and hybrid lines (including 6 local cultivars, 14 selected and introduced varieties, 3 hybrid lines) were treated with Roentgen ray irradiation, Gamma Ray ~(60)Co with doses 7, 10, 12, 15, 18, 20, krad, and with chemical mutagens: EI, NMU, DNMU, DES, EMS, DEU with various concentrations 0.008, 0.02, 0.04, 0.06, 0.08 percent. As the results, we obtained the important conclusions about the rule of induced mutation process in soybean in the natural conditions of Vietnam. 8 mutant varieties (1National varieties (DT84) and 6 regional production varieties (DT83, DT90, DT94, DT95, DT99, AK06 (DT-55). Several promising varieties were selected and released for farmers to produce in the large areas that occupied 50-90 percent percentage of soybean cultivated areas in Vietnam. These varieties have high-yield 1.5-3.5tons/ha, short growth duration 75-100days, tolerance to cold and hot temperature and can be planted in 3 crops per year (Winter, Spring and Summer season) over 35-40 thousands ha/year. At present, the mutagens are being used for defect-orientated repair of some promising hybrid lines, in order to contribute new good varieties to soybean production in Vietnam.
