提高自花授粉作物产量的进展已促进了雄性不育和其它异交机制的研究,而这种机制在轮回选择中可增加基因重组。已有报道认为,大田花生的自然异交率最高为6%,还不能产生足够的基因重组以供选择。诱变处理能提高自花授粉作物如燕麦、小麦、大麦的异交率。在诱变处理中,用γ Advances in increasing the yield of self-pollinating crops have contributed to the study of male sterility and other outcrossing mechanisms that can increase genetic recombination in alternative cycles. It has been reported that the highest natural rate of natural outgrowth in Daejeon peanuts is 6%, which still can not generate enough gene recombination to choose from. Mutagenesis improves the rate of outgrowth of self-pollinating crops such as oats, wheat and barley. In mutagenesis treatment, γ is used
