摘要： 分析小麦功能叶与主要灌浆参数之间的相关性，为山西地区小麦的高产育种提供参考依据。以51 个山西小麦品种为试材，用Logistic 方程拟合花后籽粒干重变化规律，分析叶片与主要灌浆参数之间的相关性。Wt1、Wt2、Wt3、W2、W3、V3、Vm、V2、Va等为主要灌浆参数；旗叶倾角与Wt1、Wt2、Wt3、W2之间的相关性达到显著水平；旗叶面积与Wt1、Wt2、W2显著相关；倒2 叶面积与Wt1、Wt2、W2、Va之间的相关性达到显著水平；粒重叶比（穗粒重/旗叶面积）与Wt2、W2、Va显著相关。在小麦的高产育种中，应注重对旗叶倾角、旗叶面积、倒2叶面积以及粒重叶比的考察与选择，以获得最佳的灌浆效果，为高产育种奠定基础。

Abstract: The objectives of this study are to analyze the correlation between functional leaves and main grain filling parameters in wheat, and provide references for high-yield breeding of wheat in Shanxi. A total of 51 wheat cultivars from Shanxi Province were used as materials to fit the change regularity of dry weight of grain after flowering using the Logistic equation, and the correlation between main filling parameters and functional leaves was analyzed. The results showed that the main filling parameters were Wt1, Wt2, Wt3, W2, W3, V3, Vm, V2 and Va, correlations between flag leaf inclination and Wt1, Wt2, Wt3, and W2 were significant; the flag leaf area was significantly correlated with Wt1, Wt2, and W2; the second leaf area was significantly correlated with Wt1, Wt2, W2 and Va; significant correlations existed between the spike grain weight/flag leaf area (SGW/FLA) and Wt2, W2 and Va. In high-yield breeding of wheat, we should pay attention to the investigation and selection of flag leaf inclination, flag leaf area, the second leaf area and the spike grain weight/flag leaf area in order to obtain the best filling effect and lay a foundation for high yield breeding of wheat.
