| 摘 要： | 以粤光S为不育基因供体,与具有广东野生稻亲缘的优质常规稻种质增城丝苗-8选杂交,经多年系谱选择和测交筛选,育成水稻光温敏不育系广3S.该不育系具有不育起点温度较低、开花习性好、异交结实率高、抗寒性强、配合力强、米质较优、综合农艺性状优良等特性,2010年7月通过广东省技术鉴定.以广3S组配的广两优931、广两优802等两系杂交稻新组合在广东省区试中呈现丰、抗、优协调特性,具有广阔的应用前景.

| Abstract: | Guang 3S,developed from the cross between Yueguang S(the donor of male sterile genes) and Zengchengsimiao-8 Xuan(a fine quality rice variety with genetic background of Guangdong Wild Rice) by pedigree selection over years,is a new photo-and thermo-sensitive genic male sterile(PTGMS) line in rice.It has such characteristics as a low critical temperature for fertility alteration,good flowering habits,high outcrossing rate,strong cold tolerance,high combining ability,good grain quality and desirable integrated... |
