Heterosis study on 4x Mt CMS and its maintainer line of non-heading chinese cabbage

  • 摘要: 以4xMtCMS为母本,6个四倍体不结球白菜自交系为父本配制杂交组合,测定其杂种优势。结果表明:与相应父母本相比,四倍体杂交组合杂种6个F1产量均表现正的中亲和超标优势,以4xMtCMS×07P-10和4xMtCMS×07P-8的产量杂种优势最强,中亲优势、超亲优势及超标优势最大分别达18.90%、15.27%和12.61%,株高、开展度、叶片数、叶面积和单株产量等农艺性状杂种优势普遍存在;品质性状显著高于父母本,平均中亲优势均表现为正向优势,但优势率较小,平均超亲优势、超标优势杂种优势不明显。
    Abstract: Six crossing combinations were obtained by using 4x MtCMS line and 6 inbred lines of non-heading Chinese cabbage. Agronomic traits and heterosis of the F1 hybrids were studied. The result indicated that the main agronomic traits had a significant heterosis in the hybrid of non-heading Chinese cabbage. Yield per plant of 6 F1 hybrids had a certain degree of positive mid-parents and over-standard heterosis. Two of the hybrids,namely 4x Mt CMS?07P-10 and 4x Mt CMS?07P-8,were the largest. The mid-parents,over-parents and over-standard heterosis showed 18.90%,15.27% and 12.61%,respectively,in yield per plant. The 6 F1 hybrids were taller,the plant diameter larger,leaves thicker,leaf area larger and yield of plot greater than their parents,and these differences were significant. Quality was improved over their parents,and the mid-parents heterosis was positive but in minute amounts. The heterosis of the over-parents and over-standard were not significant.
