摘  要:
利用植物数量性状主基因+多基因混合遗传模型,以高淀粉玉米杂交组合"郑单958"的P1、F1、P2、B1∶2、B2∶2和F2∶36个家系世代为材料,多世代联合分析了高淀粉玉米主要性状的遗传效应。结果表明:穗长、穗位高由多基因控制;百粒重、单穗重、行粒数、株高由1对加性主基因+加性-显性多基因控制;秃尖长由1对加性-显性主基因+加性-显性多基因控制。

摘  要:
Genetic effects of main traits of high-starch corn were analyzed,using the mixed major gene+polygene genetic model of plant quantitative traits,with the combination of high-starch corn hybrids "Zhengdan 958" of P1,F1,P2,B1:2,B2:2and F2:3,6 families from generation to genEration,as the material.The results showed that:ear length and ear height were controlled by polygenes;100-grain weight,single spike weight,grain number per row and plant height were controlled by 1 pair of additive major gene+additive-dominant polygene;Bare tip length was controlled by 1 pair of additive-dominant major gene + additive-dominant polygene.
