| 摘 要： | 对86个小麦品种(系)进行了农艺性状的调查与分析，发现在有效分蘖、生育期、株高和千粒重等农艺性状方面存在显著差异，而且存在着较大的极差。不同品种(系)间开花期的最大极差为25d，有效分蘖的最大极差达18个，株高的极差达0．91m，穗粒数极差达到47．8粒，千粒重的最大极差达39．6g，质量性状中也存在着许多明显的差异。这些表明在河北师大生命科学学院园地的小麦品种资源中存在着极其显著的遗传差异。

| Abstract: | The agronomic traits of 86 wheat varieties (or lines), which were planted in the garden plot of the Life Science College of Hebei Normal University,were studied and analyzed.It was found that there was distinct difference on the productive tillers,the developmental period,the plant height and the 1000-grains weight.Among the different varieties (or lines),the widest range of the blooming date can be 25 days, that of the productive tillers can be 18 tillers, that of the plant height can be 0.91m,that of the grain number per ear can be 47.8 grains and that of 1000-grains weight can be 39.6g.Many distinct differences were also found in the qualitative traits. |
