籼型光温敏两系不育系绿102S(102S)的选育及特性

Breeding and Characteristics of Indica Two-line Photo-thermo-sensitive Male Sterile Line Green 102S(102S)

[目的]选育及推广优质籼型光温敏两系不育系水稻。[方法]以安湘S为母本,与广亲和籼三系恢复材料L09选(轮回422/78039)杂交,然后在其分离后代中进行选择。[结果]经5年9季,于2003年冬季选出基本稳定的优质抗倒籼型光温敏两系不育系。该不育系育性稳定,育性转换起点温度低,在海南可繁性好,早熟,品质优良,抗倒性好。[结论]绿102S(102S)值得推广。

[Objective] The study aimed to breed and extend the high quality rice indica two-line photo-thermo-sensitive male sterile line.[Method] With Anxiang S as female parent,crossing with Guangqin and L09Xuan,and then select the high quality material in the filial generation.[Result] The basically stable and high quality indica two-line photo-thermo-sensitive male sterile line was selected out in winter of 2003.the sterile line had stable fertility,low fertility alteration threshold temperature,good reproductive ability,early maturity,excellent quality and good lodging resistance in Hainan Province.[Conclusion] This variety was worthy to be popularized.
