- 摘要:
- 用60Co-γ射线对晋豆24号风干种子进行了辐照处理,对M4代14个突变株系及CK的10个主要农艺性状进行了相关分析、主成份分析及聚类分析。相关分析表明:单株产量与株重、有效分枝、主茎荚数、株荚数、株粒数呈极显著相关;主成份分析表明:前3个主成份(单株个体因子、株形因子、粒重因子)对变异的贡献率达86.92%;聚类分析把后代分为5类,每类的产量差异显著。结果表明,农艺性状的遗传关系分析对选育新品种具有重要的意义。
- Abstract:
- The dry seeds of Jindou 24 had been irradiated with 60Co-γ ray,and analyzed ten main agronomic characters in the 14 soybean lines of mutants and CK using correlation analysis,principal component analysis and cluster analysis.The results of correlation analysis revealed that the seed yield per plant correlated significantly with weight per plant,branches,pods of stem,pods per plant and seeds per plant.The results of principal component analysis showed that the cumulative ratio of contribution of first three components including plant individual factors,plant shape factors and seed weight factors to the total variation reached 86.92%.The mutants weres divided into 5 groups using cluster analysis,the yield difference of each group was significant.The results of genetic relationship analysis on agronomic character showed that it was very important to cultivate new varieties.
