Abstract:

Analysis of agronomic and economical traits for 7 peanut varieties were carried out by using the data of peanut test in 4 locations. The results showed that the traits had more differences in varieties and in locations. Among the traits, number of branches per plant, number of pod branches per plant, number of pods per plant and full pods per plant were influenced obviously by ecological factors, and shelling rate was relatively stability in locations. Taihua 5 showed high yield potential, adapted to plant in huainan region in Jiangsu.Taihua 2 adapted to plant in Nanjing, Rugao and Xuyi locations. Huayu 23 was of more high yield potential and yield stability, adapted to plant in Nanjing, Rugao and Sihong locations.
