摘要
不同叶形的4个品种(系)叶长、叶宽、叶片大小、叶柄长度和叶张开角度等性状与百粒重、每荚粒数、籽粒产量等性状的相关分析表明:(1)叶长、叶形指数、叶长×叶宽、叶宽等性状的中间小叶与侧小叶间的相关系数均达极显著水平.(2)叶长、叶宽、叶柄长度、叶张开角度、叶面积间仅叶柄长度与单叶面积呈显著正相关,其它性状间的相关均不显著.(3)叶形指数与二粒荚数呈极显著正相关,其它叶部性状与每荚粒数间的相关均不显著.(4)三出复叶中间小叶和侧小叶的叶部性状与百粒重间相关均不显著.(5)叶长与有效分枝呈极显著正相关,叶形指数与分枝荚数、总粒数呈显著或极显著正相关,其它叶部性状与产量间的相关均不显著.因此,长叶或宽叶品种均可选出高产品种.
The relationship of leaf characters (Sach as leaf length , leaf wideth, leaf size, length of leaf handle and leaf angle) and main agronomic characters (sach as 100 seeds weight, number of seeds per pod and yield) were examined for 4 soybean cultivars (lines). The results are summarized as follows:
1 . The correlation of leaf length, index of leaf form , leaf length, leaf width, and leaf width of middle leafit with that of leafit of side were significantly crrelation coefficient was respectively 0.911, 0.996, 0.994, 0.995, respectively.2. Only the length of leaf handle on the leaf characters was modertely significantly and positively correlated with a piece of leaf area (r=0.957). It was no significant relationship between the characters of the others.
3 . The correlation of the index of leaf form with the number of pod per two seeds was significantly positive conversely, the leaf characters of the other was no significantly correlated with the number of seeds per pod.
4. The leaf characters of middle-leafit and leafit of side were no significantly correlated with 100 -seeds weight.
5 . The leaf length was significantly correlated with effective branches (r=0.999) . The index of leaf form was positively correlated with the number of branches per pod and the abrount of seeds, the leaf characters of the other was yet no significantly correlated with yield. Thus, we can not ignore the selection of leaf characters in the breeding of high yield.
