| 摘 要： | 目的]研究粳稻三系亲本壹子间性状的相关性。方法]以BT型粳稻不育系、保持系及恢复系各16个为供试材料，配制229个杂交粳稻组合，测定其农艺性枕、产量性状和品质性状，并对数据进行相关性分析。结果]杂种的多数性状由不育系和恢复系共同决定，杂种与中亲值的相关性最好，杂种与高亲值的相关性一般好于与低亲值的相关性。抽穗期、穗总粒数等性状与不育系关系较为密切，株高、穗实粒数、结实率、单株产量、品质性状与恢复系关系较为密切。所有产量性状亲子间的相关系数均小于0．7。说明杂种的产量性状还与双亲的特殊配合力有密切的关系。结论]该研究为杂交粳稻育种提供配合力好的亲本资源，并为生产应用提供优质高产的杂交粳稻组合。

| Abstract: | Objective] The purpose was to study the correlation of traits between parent and parent-child of three-line japonica rice.Method] With male sterile lines,maintainer lines and restorer lines of BT-type japonica rice as test materials,229 hybrid japonica combinations were prepared and their agronomic traits,yield traits and quality traits were determined to make correlative analysis on the obtained data.Result] Most traits of hybrid were decided jointly by male sterile lines and restorer lines.The correlat... |
