用 AMMI 双标图分析西瓜品种的产量稳定性及试点分辨力
AMMI-biplot analysis of yield stability and test-sites resolution of watermelon varieties
摘要
Abstract
The AMMI model was adopted to analyze the output data of watermelon varieties in regional trial in 2009 . The results showed that the genotype effect (G) accounted for the largest proportion ,followed by the environment effect (E) ,while G × E interactive effect was the smallest but still reached extremely significant level .There were significant differences in stability of the eight varieties and resolution of the four testing sites .Among the eight varieties ,the stability parameter of G4 (09 -N2) was the highest (Dg = 15 .53360) and that of G7 (09 -N9) was the lowest (Dg =2 .56881);G2 (09-N1) and G1 (09-N7) were the varieties with high -yield and high-stability ,G4 (09-N2) and G6 (09-N12) were the varieties with low-yield and low-stability ,G8 (CK ,09-N15) was the variety with high-yield and mid-stability ,G7 (09-N9) was the variety with low-yield and high-stability ,G3 (09-N5) was the variety with mid-yield and mid-stability ,and G5 (09-N8) was the variety with mid-yield and low-stability .As for the four testing sites ,Lanzhou (in Gansu) was the site with a powerful resolution of watermelon varieties ,Zhongwei (in Ningxia) and Zhongning (in Ningxia) were the sites with a moderate resolution ,and Haiyuan (in Ningxia) was the site with a poor res-olution .关键词
