| 摘 要： | 应用灰色关联分析方法 ,分析了 6个水稻品种 2 1个株型性状对单株产量的影响。结果表明 :单株产量与 2 1个株型性状的关联序依次为 :剑叶厚 >倒二叶厚 >剑叶宽 >倒二叶宽 >倒二叶鞘长 >剑叶鞘长 >倒二叶弦长 >倒三叶宽 >倒三叶厚 >倒三叶鞘长 >剑叶长 >倒二叶长 >倒三叶长 >剑叶弦长 >倒三叶弦长 >倒三叶基夹角 >倒三叶叶开角 >剑叶叶开角 >剑叶基夹角 >倒二叶基夹角 >倒二叶叶开角。

| Abstract: | The relationship between yield per plant and 21 plant type traits of 6 paddy rice cultivars was analyzed with the method of Grey Correlation Degree Analysis. The results showed that the order of relational grades of 21 plant type traits to yield in 6 paddy rice cultivars was thickness of the flag leaf, thickness of the 2nd backward leaf, width of the flag leaf, width of the 2nd backward leaf, sheath length of the 2nd backward leaf, sheath length of the flag leaf, edge length of the 2nd backward leaf, width of the 3rd backward leaf, thickness of the 3rd backward leaf, sheath length of the 3rd backward leaf, length of the flag leaf, length of the 2nd backward leaf, length of the 3rd backward leaf, edge length of the flag leaf, edge length of the 3rd backward leaf, basal angle of the 3rd backward leaf, leaf angle of the 3rd backward leaf, leaf angle of flag leaf, basal angle of the flag leaf, basal angle of the 2nd backward leaf and leaf angle of the 2nd backward leaf, respectively. |
