| 摘要: |
| 对小麦产量性状及形态性状(共32个)之间多元关系进行了分析,结果表明,如下株型有利于群体产量的形成:植株高度为80cm 左右,茎高整齐一致,穗下节不宜太长,倒一叶间距/倒三叶间距的比值小,旗叶角度/旗叶宽度<26.8,旗叶长度/旗叶宽度>16.7。旗叶角度/有效穗数>0.42,各性状之间的合理组合关系是动态的。本研究除用线性逐步回归方法寻找与产量三因素关系密切的形态性状外,还应用非线性模式对部分形态性状之间关系进行了分析。 |

| Abstract: |
| The relationship between multiple morphological traits of wheat was stud- ied,the results showed that the rational combination of traits,such as plant-height,Plant-eveness,peduncle-length(PL),the distance between nodes(DBN),flagleaf-lengh(FL),flagleaf-width(FW),flagleaf- angle(FA)and the number of ear-tiller(NE),could bring the prod- uctive potentiality of plant-population into full play.The ideotype are as follows,the plants are about 80 cm high and grow evenly,Plis short comparatively,DBN.NO.1(from above)... |
