| 摘 要： | 红莲质源不育系丛广４１Ａ属配子体不育，圆败花粉类型，其柱头外露率比珍汕９７Ａ高，包颈率较低，盛花期早，有利于制种。广优青是用丛广４１Ａ与特青２号配组的迟熟杂交早稻组合，１９８８年参加广东省区试，平均亩产４７８．５公斤，居９个参试组合之首，比对照汕优６３增产。１２．７１％，且比汕优６３早熟１天；该组合宜在广东省东部和中南部地区作早造栽培。

| Abstract: | Cong-Guang 4lA.a male sterile line of Honelian cytoplatsm source,is of gametopbytic steri- lity. and its pollens belong to spherical abortion type.Its panicle exsertion percentage is higher and blooming stage is earlier,when compared to those of Zhen-Shan 97A. These good characteristics are favourable for seed produc- tion. Guang-You-Qing is a late maturing com- bination made with Cong-Guang 41A and TeQing 2. In 1988 this combination participated in the regional trial in Guangdong Province. Its yicld was 478.5 Kg per mu. which was higher than that of other 8 hybrid combinations tested and 12.71% higher than that of the control Shan-You63. It would be suitable to plant Guang-You-Qing in the east or middle south of Guangdong Province as early season crop. |
