大穗大粒小麦品种穗部性状与产量的关系

The Relationship Between Ear Characters and Yields of Wheat Varieties with Big Ears and Heavy Kernels

通过7个大穗大粒小麦品种（系）的田间小区控制性试验，分析了小麦穗部性状与产量之间的相关关系，探讨了进一步提高小麦大穗大粒型品种的产量的途径。结果表明，进一步提高大穗大粒品种的个体和群体产量，宜走提高穗粒数的路子。在保持一定的粒重水平的基础上，选育多小穗品种，采用适宜大穗大粒品种生长发育的栽培技术，以增加每穗小穗数，特别是增加结实小穗数，减少退化小穗数。

The correlative relationship between ear characters and yields of wheat variety has been studied. The ways further to increase yield of wheat varieties with big ears afld heavy kernels have been approached. The data indicate that in order to increase yield of the varietles,the way by which grain counts per ear are increased should be taken.
