摘　　要：本文详细叙述了棉花混选—混交新育种方法的程序及其育种效果。在混选一混交后的群体中已选得一批新品系,其产量、品质、抗性等方面接近或超过中棉12。新品系1276和164参加了省级以上品种区域试验,表现较好。而同时采用常规的杂交育种法未能选到优良品系。不去雄混交法可保证较高比例异交率,从而使这种新育种方法具有较好的应用前景。The program of the new cotton breeding method of mass selection-mass crossing is described and the results of breeding cotton is presented in this paper. Some new varieties (or strains), which are equivalent to or superior to the standard variety Zhongmian12 in yield, fiber properties and disease resistance, were selected through the new method. The varieties (strains) Zhong 1276 and Zhong 164 from the mass selection-mass crossing populations were tested in the Henan regional variety trials in 1990-1991 and...
