| 摘 要： | 选用穗高系数有显著差异的甜玉米自交系T14和T4为亲本配制杂交组合,用主基因＋多基因混合遗传模型和P1、P2、F1、B1、B2和F2共6个世代联合分析的方法对穗高系数性状进行分析;以330个F2单株为分离作图群体,用复合区间作图法在F2和F2：3家系中检测穗高系数QTL。通过研究玉米穗高系数的遗传模式和QTL定位,为玉...

| Abstract: | To obtain the theoretical basis for breeding high yield and lodging-resistant corn under high density cultivation condition,genetic model and mapping for corn ear-hight-coefficiency(EHC) was investigated.Cross combination was designed by selecting two sweet corn inbred(T14 and T4) with significantly different EHC.Genetic segregation analysis for EHC was evaluated using major gene-polygene mixed inheritance models and joint analysis of P1,P2,F1,B1,B2 and F2 populations.A genetic mapping population of 330 F2 ... |
