Abstract:
      even genotypes of wheat varieties were used to research the relation between normalized difference vegetation index (NDVI) and yield components and drought resistance under dryland conservation tillage condition.The results showed that NDVI values of different wheat genotypes differed significantly at different development stages.Value of wheat NDVI expressed a positive correlation with drought yield index at heading stage.Those who had higher NDVI value of heading had better drought yield index.Under the experimental conditions Shimai15 Shijiazhuang8and Yan Blu6439have higher drought yield index than others.
