紫标S系是杂交育成的具紫叶隐性遗传标记的、不育起点温度低的籼型两用核不育系。在日长14小时/天,日均温24℃左右(19~27℃变温)人控条件下,以及在贵州贵定(北纬26°35’,海拔1006米)自然光温条件下,不育期的花粉不育度99.9%以上。套袋自实率为零。不育度达99.5%以上的不育株率为100%。不育期41天以上。育性转换明显。可育期自实率为21.4%~54.1%。农艺、异交性状优良。具有制种安全、易繁殖、易除杂等实用价值。
Purple standard S line is a hybrid bred purple leaf recessive genetic markers, low starting point of sterile indica dual-purpose nuclear male sterile line. Under the artificial light conditions of 14 hours daily / day, daily average temperature about 24 ℃ (19-27 ℃ temperature change) and natural light and temperature in Guiding (latitude 26 ° 35 ’, elevation 1006 m) The pollen sterility is more than 99.9%. Bagging from the real rate of zero. Sterile rate of more than 99.5% of sterile plants was 100%. Sterile period of 41 days or more. Fertility conversion is obvious. Fertility period since the real rate of 21.4% ~ 54.1%. Agronomy, excellent cross-sex traits. With seed security, easy breeding, easy removal of impurities and other practical value.
