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。
Guangdong Guangsheng S as male sterile gene donor, with the relatives of wild relatives of Guangdong wild rice germplasm Zengcheng Miao-8 election hybrids, after years of pedigree selection and cross selection screening, breeding of rice light-temperature-sensitive genic wide 3S . The male sterile line has the characteristics of low starting point of infertility, good flowering habit, high outcrossing rate, strong cold resistance, strong combining ability, better quality of rice and superior agronomic characters. In July 2010, it passed Guangdong Province Technical appraisal The new combination of Guangliangyou 931, Guangliangyou 802 and other two-line hybrid rice with Guangsan 3S exhibited abundant, anti-and excellent coordination characteristics in the Guangdong Provincial District Test, which has broad application prospects.
