摘　　要：“金丰”是由 92冬繁 2 / 92冬繁 1杂交选育而成的中熟晚粳良种。其特点是产量高而稳 ,一般产量8.5～ 9.0t/hm2 ,高产栽培可达 10 .5t/hm2 以上 ;米质优 ,食味佳 ,经检测其 9项指标达国家优质米一级标准 ,2项为二级标准 ;抗稻瘟病且抗谱广 ;它既能育秧栽插 ,还能用于直播栽培。是一个单晚和双晚兼用型品种。目前正在推广之中且面积迅速扩大。“Jinfeng” is a medium-maturing late japonica rice variety bred by crossing 92 Dongfan 2 with 92 Dongfan 1. It is mainly characterized by high and stable yield, and strong resistance to rice blast. When planted as a single-cropping late rice, the yield of “Jinfeng” was 8.5～9.0t/hm 2, and the high yield could be more than 10.5t/hm 2. In addition, the rice quality of “Jinfeng” is up to the 1st grade standard of high quality rice issued by the Ministry of Agriculture in terms of brown rice rate, milled rice rate, head milled rice rate, grain length, length/width ratio, alkali digestion value, gel consistency, amylose content, and protein content, and up to the second grade standard in terms of degree of chalkiness and transparency. The rice “Jinfeng” yields well when grown by way of transplanting rice seedlings ordirect seeding, which can be planted as a single cropping late rice or a double cropping late rice, and its planting area is increasing rapidly at present.
