花生是广西的主要油料作物 ,年播种面积达 2 0 0khm2 左右 ,由于地处亚热带 ,常年高温多雨 ,花生生长后期锈病严重 ,致使产量减收 10 %左右 ,为了解决这一问题 ,我们选育出抗锈病花生新品种桂花2 1。桂花 2 1(原编号 96 7春 - 6 )具有早熟、高产、高抗锈病、抗倒伏等优良性状 ,1997~ 1999年参加广西花生品种区域试验 ,3年 18个点次平均单产荚果 32 82kg/hm2 ,比对照种汕油 2 7增产 2 9% ,2 0 0 0年参加广西花生新品种试验示范 ,平均单产荚果 4 750kg/hm2 ,比对照桂花 17增产 2 6 % ,适合广西水田旱地种植
Peanut is the main oilseed crop in Guangxi. The annual sown area is about 200kh2. Since it is located in the subtropical zone with perennial high temperature and rainy weather and serious peanut rust in the late growth stage, the yield is reduced by about 10%. In order to solve this problem, we breed Anti-rust disease new varieties of peanut osmanthus 2 1. Osmanthus fragrans 2 1 (formerly No. 96 7 Chun-6) has good traits of early maturity, high yield, high resistance to rust and lodging resistance. From 1997 to 1999, it took part in Guangxi peanut variety regional test. The average yield per plant at 18 points in 3 years was 32 82 kg / hm2, 19% more than that of Shantou 27, and participated in Guangxi peanut new variety experiment and demonstration in 2000. The average pod yield was 4750kg / hm2, which was 26% higher than that of Guihua 17, which was suitable for dryland cultivation in paddy field of Guangxi
