pollen sterility

Its critical sterility inducing temperature ( CSIT) was low at about 23.5 ℃. Grown in Hefei, it had a long stable sterile period over 30 days with 100% sterile plant rate, 99.99% pollen sterility rate and no bagged selfed seed set.

2301S不育株率100%，花粉败育率99.99%，套袋自交不实率100%，不育起点温度较低，在合肥不育期30d以上；

genetic analysis demonstrated that the non-pollen sterility in xians was controlled by a single recessive gene.

遗传分析表明无花型籼S是受单隐形基因控制的。

the waxy male-sterile line had the same pollen sterility characteristic as its parent male-sterile line.

糯不育系具有与原不育系相同的花粉不育特性。
