摘 要 ：用30个遗传差异不大的Mo17改良系作用与Mo17组成姊妹种（A1×A2），再以30个姊妹种以及30个Mo17改良系作母本，与父本自交系E28，5003配成改良单交种和普通单交种，试验表明：改良单交种的产量、农艺性状和整齐度与相应的普通单交种基本一致，而姊妹种的产量明显地高于任一亲本自交系，故改良单交种具有制种产量高的优点。姊

Abstract:Each of the thirty improved lines of Mo17 was crossed as female parent with Mo17 to produce the sister crosses. These sister crosses and improved lines all were crossed with two male parents, 5003 and E28, to produce modified single crosses(A1×A2)×B and normal single crosses. The grain yields
