随着小麦育种水平的不断提高,人们越来越重视株型育种。在株型中,株高已进行了较充分的研究,而对籽粒灌浆有重要作用的旗叶性状、穗部绿色面积、穗下茎节长度及其与株高的比值,它们和穗粒性状关系的研究相对较少。为此,我们在1984、1986两年对小麦几个株型性状和穗粒性状的相关性进行了研究和通径分析,为小麦育种和提高栽培水平提供依据。一、试验材料及方法
As the level of wheat breeding continues to increase, people pay more and more attention to plant type breeding. In the plant type, plant height has been more fully studied, and grain filling plays an important role in the flag leaf traits, spike green area, ear stem length and its ratio of plant height, and their grain traits The relationship between the research is relatively small. To this end, we conducted a study and path analysis of several plant-type traits and grain-ear traits in wheat in 1984 and 1986, providing a basis for wheat breeding and raising the level of cultivation. First, the test materials and methods
