根据我们十多年来对旱地春小麦育种和栽培实践的经验,深感春小麦品种的形态特征与它的抗旱性强弱有着很大的相关性。为此,我们白1982年以来,对旱地春小麦品种抗旱性的形态指标作了观察测定,目的是为春小麦的旱地育种提供一些形态选择依据,以利于加速春小麦的育种进程,现把观察结果初步整理如下。 1.株高:根据1982年482个种植在旱地的春小麦植株高度的统计分析(表1)表明株高 Based on our experience in spring wheat breeding and cultivation practices in drylands for more than a decade, it is deeply felt that the morphological characteristics of spring wheat varieties are strongly correlated with their drought resistance strength. For this reason, we have observed and measured the morphological indices of drought resistance of spring wheat cultivars since 1982 in order to provide some morphological basis for spring wheat breeding in dryland in order to accelerate the breeding process of spring wheat. as follows. 1. Plant height: Based on the statistical analysis of 482 spring wheat plants planted in dry land in 1982 (Table 1), plant height
