摘要
[目的]进一步了解花生杂种优势特点。[方法]选取以2个高产品种(系)粤油7号和ZK04为母本,新会小粒、六月雪、J11、Q02和洲仔小粒5个品种为父本配置的6个杂交组合F1真杂种为材料,分析了主茎高、侧枝长和茎粗3个株型性状及饱果数、单株荚果重和荚果大小3个荚果性状的超亲优势和中亲优势。[结果]大部分组合的F1代在主茎高、侧枝长和茎粗性状上均有超亲或正向中亲优势;在饱果数、单株荚果重和荚果大小上,大部分组合的F1代都不存在超亲优势,只有少部分组合的F1代存在正向中亲优势。[结论]花生杂种优势随性状和材料不同而不同。
[ Objective ] In order to understand the heterosis in peanut. [ Method ] The F1 plants of 6 crosses, the 2 high yield varieties （line） Yueyou7 and ZK04 as the receptors,5 varieties of Xinhuixiaoli, Liuyuexue ,J11, Q02 and Zhouzixiaoli as the donors, were selected as the materials. The over-high parent heterosis and mid-parent heterosis of 3 plant characters, the main stem height, the primary branch length and the main stem diameter,and 3 pod characters,a number of filled pods per plant,the weight of pods per plant and the size of pod,were analyzed. [ Result] The main stem height ,the primary branch length and the main stem diameter of F1 showed over-high parent heterosis or positive midparent heterosis in most crosses. A number of filled pods per plant ,the weight of pods per plant and the size of pod of F1 didn＇ t showed over- high parent heterosis in most crosses and showed positive mid-parent heterosis in a few crosses. [ Conclusion ] The heterosis varied with the characters and varieties in peanut.
