小麦苗期抗旱性决策评价和抗旱指标计算法

Algorithm of Drought Resistance Indices and Evaluation of Its Decision-making in wheat Seedling Stage

在理论分析基础上,提出计算作物抗旱指标的简便而可靠的一种方法,据此对20个小麦材料的苗期抗旱性进行评价鉴定,筛选出苗期抗旱性较好的部分类型,多属性决策法实用,准确和灵活,宜在品种评价和鉴定中普及应用。

Based on the theoritical analysis,this paper presents a reliable and simplealgorithm for calculating drought resistance indices of crops.According to thisalgorithm,the drought resistance of 20 types of wheat materials were evaluated,and several better types of them were screened in the seedling stage.Multi att-ributive decisionmaking was characterized by practical application,accuracy andflexibility.So that it can be widely used in seed evaluation and identification.
