These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

为此，该文将平均值、方差、均一性、反差、相异性、熵、角二阶矩、灰度相关7种纹理信息以及比值植被指数、土壤调整植被指数、重归一化植被指数、植被液态水含量指数、有效叶面积植被指数5种植被指数信息分别加入到TM多光谱数据中，同时还进行了最佳波段选择，利用最小距离、最大似然和支持向量机3种方法进行分类提取小麦，研究了不同特征信息对小麦测量精度的影响。

The effects of aphid harmfulness on yield and main nutritive qualities were different in the three different wheat stages.

蜜露危害对小麦产量与主要营养品质的影响，在小麦3个生育期之间存在一定差异。

In this study, AFLP markers for YrSp gene were identified and SCAR markers were developed using the near-isogenic line YrSp/6 x Avocet S and its susceptible parent Avocet S as materials with the YrSp gene donor parent Spaldings Prolific as control. The main results were given as follows:1. A total of 225 primer combinations were used in AFLP analysis of the materials YrSp/6×Avocet S, Avocet S and Spaldings Prolific.

本研究采用AFLP分析方法，以小麦抗条锈病基因YrSp的供体亲本Spaldings Prolific、近等基因系YrSp/6 x Avocet S、轮回亲本Avocet S及由Avocet S和YrSp/6 x Avocet S杂交制备的F_2代分离群体为材料，开展了小麦抗条锈病基因YrSp的分子标记研究，取得了如下主要结果： 1。
