| Abstract: | The tested data derived from 94 different wheat varieties under the drought conditions on Weibei rainfed areawere used to establish the regression relation between yield and its components of wheat and conduct the path analysis The result shows that the most important factor of high production for high-yielding varieties is the number of grains per spike in different grouped wheat, and in the whole wheat
varieties, the contributions of yield components to yield are that the available tiller is the most, and the 1000 kernel weight is the least This paper has also put for ward the wheat breeding way of increasing the number of certain tiller, stabiliting the 1000 kernel weight and improving the kernels per spike potential in Weibei rainfed highland, Shaanxi Province. |
