一种基于考种数据的水稻抗旱性评价方法
By using a simplified evaluation method based on rice variety test data, the heading delay effect and harvest index are calculated using conventional rice variety test data, and five comprehensive drought resistance indicators are constructed. This solves the problem that existing methods for identifying rice drought resistance are complex and costly, and realizes a simple, easy-to-use, and accurate quantitative evaluation of rice varieties.

Abstract
本发明提供了一种基于考种数据的水稻抗旱性评价方法，通过对实验水稻品种进行梯度量化控水管理，结合考种，对性状数据进行详细观测记录，然后对不同参试品种的单株生物学产量、单株籽粒产量、单株有效穗数、每穗实粒数、千粒重、播抽天数等性状进行分析，得到各品种在梯度量化控水条件下产量等性状对土壤水分条件变化响应的总效应；在此基础上，计算各性状T值的5个多梯度多性状复合抗旱指标，根据这5个多梯度多性状复合抗旱指标，对各实验组的节水抗旱性进行分析鉴定，并达到良好的判别目标，最终实现利用常规考种数据对杂交稻组合的节水抗旱性进行梯度量化控水条件下的综合评价。
