不同花生品种生产力的比较

对7个花生品种在4个试点的农艺性状和经济性状进行分析，比较不同花生品种的生产力及其应用前景。结果表明：不同品种以及同一品种在不同试点其农艺和经济性状均存在明显差异，其中，单株总分枝数、单株结果枝数、单株总果数和单株饱果数较易受环境影响，而出仁率较为稳定性。泰花5号产量潜力较高，适合本区域种植。泰花2号适合在南京、如皋、盱眙等地区种植。花育23号也具有较高的产量潜力，且产量稳定性较好，适合南京、如皋、泗洪等地区种植。

Analysis of Agronomic and Economical Traits for Different Peanut Variety

Agronomic and economical traits were studied by using the data of peanut regional tests in 4 locations with 5 peanut varieties from Jiangsu province and 2 peanut varieties from Shandong province. The results showed that the traits display significant differences in varieties and in locations. Among those traits, number of branches per plant, number of pod branches per plant, number of pods per plant and full pods per plant were effected obviously by ecological factors, and shelling rate was relatively stability in locations. The average yield of peanut varieties was 4032.0 kg/hm 2 , varied from 3604.5 kg/hm 2 to 4461.0 kg/hm 2 . The yield of ‘ Taihua 5 ’ was highest and ‘ Huayu 20 ’ was lowest in peanut varieties. ‘ Taihua 5 ’ showed higher yield potential and mixed up of yield characters, adapted to popularize in huainan region in Jiangsu. ‘ Taihua 2 ’ adapted to plant in Rugao and Xuyi. ‘ Huayu 23 ’ was of higher yield potential and yield stability, adapted to plant in Nanjing, Rugao and Sihong.
