依据水稻光（温）敏不育系育性变化的实验结果，提出衡量不育系育性变化规律的特征值及其量化模型。并用７个不育系的多点多年育性资料验证该模型的合理性，介绍了鉴定不育系特征值的方法和程序
Based on the experimental results of the fertility changes of the thermo-sensitive genic male sterile lines in rice, the eigenvalues and quantitative models for measuring the fertility variation of the sterile lines were proposed. The multi-point and multi-year fertility data of 7 CMS lines were used to verify the rationality of this model. The methods and procedures for identifying eigenvalues of CMS lines were introduced
