目前,国内外通过辐射与杂交相结合的办法,已选育出花生新品种,但是辐射杂交的不同处理方法对杂种一代优势和后代的选育效果的影响等报导甚少。为此,我们作了3个不同处理方法的杂交组合F_1代杂种优势的测定,以初步筛选出较优的处理方法,为进一步利用辐射杂交方法选育良种提供参考。 At present, new varieties of peanut have been bred by the combination of radiation and hybridization both at home and abroad, but the effects of different treatments of hybridization on the advantages of the hybrid generation and the breeding effect of the offspring are poorly reported. For this reason, we made the determination of F1 hybrid heterosis of three crosses with different treatment methods to screen the better treatment method, and provided reference for further breeding of elite by radiation hybridization method.
