利用 3个抗黄矮病材料作母本 ,4个丰产性品种作父本 ,采用 3× 4不完全双列杂交 ,分析 F1产量性状的遗传特性 ,结果表明 :1产量性状的遗传符合加性——显性遗传模型 ,以加性基因效应起主导作用 ;2在所有亲本材料中 ,R96330单株产量的特殊配合力方差最大 ,一般配合力效应值也最高 ,后代组合中存在极显著差异 ,是一个优良的抗病丰产亲本 ,在抗病育种中具有较大的利用价值 The genetic characteristics of F1 yield traits were analyzed by 3 × 4 incomplete diallens using 3 anti-yellow dwarf virus materials as the female parent and 4 high yielding varieties as male parents. The results showed that: 1 The inheritance of yield traits was additive - Dominant genetic model, which plays a leading role in additive gene effect. 2 Among all the parents, R96330 had the highest variance of special combining ability per plant per plant and the highest combining ability, Is an excellent disease-resistant parents, has a greater utilization value in disease-resistant breeding
