概述了旱稻的抗旱性概念及抗旱类型,分析比较了田间鉴定法、人工模拟鉴定法和实验室鉴定法等不同方法的优缺点,并对抗旱性鉴定指标(形态指标、生长发育指标)和抗旱性评价指标(抗旱系数、抗旱指数)进行了分析讨论,认为抗旱指数可作为旱稻抗旱性鉴定的首选指标。
The concept of drought resistance and the type of drought resistance were summarized. The advantages and disadvantages of different methods of field identification, artificial simulation and laboratory identification were compared and analyzed. The drought resistance identification index (morphological index, growth and development index) and drought resistance Sexual evaluation index (drought resistance coefficient, drought resistance index) were analyzed and discussed, that drought resistance index can be used as the first indications of drought resistance in the identification of upland rice.
