| 摘 要： | 光温敏核不育系具有不育期和可育期，生产上要求在不育期制种尽量提高异交结实产量，在可育期繁殖时尽量避免异交以保证繁种纯度。因此在选育不育系时，应趋利避害，选不育时开花较早、花时集中、开花高峰与正常品种吻合，受环境影响小的材料，以提高不育系的实用价值。同时由于育性和环境的影响，不育系间柱头外露率有明显差异，应选择可育时柱头外露率低，不育时柱头外露率高而且受环境影响变异小的材料。这将有利保证制种高产稳产，同时又能保证繁殖的高纯度。

| Abstract: | Objective] This study was to use reverse genic male sterile FHS better in field production. Method] Low energy nitrogen ion beam was taken as a mutation source to conduct mutagenic treatment for indica rice 99-02 and the mutant FHS with special fertility that was isolated from their offspring. Some characteristics such as flowering habit and stigma exsertion rate of FHS were observed in this experiment. Result] The reverse genic sterile rice FHS had an obvious peak flowering stage from 10:00 to 10:30, while the second peak flowering was from August 5 to August 10. Compared with PA64S, FHS flowered early and its flowering time was concentrated, showing that it is for seed propagation. The stigma exsertion rate of FHS was 85.8% and low exsertion rate was good for the purity of seed. Conclusion] The reverse genic sterile rice FHS had good value in use, besides, it could also be used as comparison material for studying fertility alternation mechanism of photoperiod sensitive genic male sterile rice. |
