Rice breeders and seed producers use this standard to evaluate the fertility of photoperiod- and thermo-sensitive genic male sterile lines. They assess sterility and fertility using artificial climate chambers and field trials to ensure hybrid seed purity and multiplication yield. This standard is critical for maintaining seed quality and production safety in two-line hybrid rice systems.
水稻育种专家和种子生产人员使用这个标准来鉴定光温敏雄性核不育系的育性。他们通过人工气候箱和田间试验评估不育系的不育性和可繁性，以确保杂交水稻制种的纯度和繁殖产量。这个标准对保障两系杂交水稻的种子质量和生产安全至关重要。

This standard specifies methods for evaluating the fertility of photoperiod- and thermo-sensitive genic male sterile (EGMS) lines of rice, using artificial climate chambers and field trials. It defines key terms such as EGMS line, degree of male sterility, fertility, and self-fertility ratio. The standard requires re-examination every three years for identified lines. Fertility evaluation is divided into sterility and fertility assessments, with self-fertility ratio as the main indicator. This standard provides technical guidance for ensuring seed purity and multiplication yield in two-line hybrid rice production.
本标准规定了水稻光温敏雄性核不育系育性鉴定的方法，包括人工气候箱群和田间试验。标准定义了关键术语如不育系、不育度、可繁性和自交结实率，并提出了鉴定要求：通过鉴定的不育系每三年复检一次。育性评价分为不育性和可育性两部分，以自交结实率为主要指标。该标准为两系杂交水稻的制种纯度和繁殖产量提供了技术依据。

This standard specifies the fertility evaluation methods for photoperiod- and thermo-sensitive genic male sterile lines of rice in artificial climate chamber groups and in the field.
Environmental sensitive genic male sterile (EGMS) line of rice is a rice male sterile line that is male sterile under long-day and/or high-temperature conditions and male fertile under short-day and/or low-temperature conditions.
The identified photoperiod- and thermo-sensitive genic male sterile lines shall be re-examined every three years according to this standard.
Taking fertility as a prerequisite, further fertility evaluation shall be conducted for sterile lines with good sterility.
The evaluation of sterility and fertility takes the self-fertility ratio as the main indicator.
