摘要
基因型与环境的互作效应(G·E)决定作物在多生态环境中产量性状的稳定性,研究红花G·E互作效应对花瓣产量稳定性的影响有重要意义。采用随机区组试验设计,选用7个红花品种,4个试验点,3次重复,测定各品种花瓣产量,运用AMMI模型对红花品种的基因型、环境及G·E互作效应进行了分析。基因型、环境及G·E互作效应均达到极显著水平,基因型占总变异的15.94%、环境效应占16.29%,G·E互作效应占47.64%,表明G·E互作效应对产量变化的影响远大于基因型和环境。互作效应主成分计算出基因型稳定性参数(Dg),顺序为‘YN1805’>‘YN2057’>‘YN512’>‘YN495’>‘YN1959’>‘YN2527’>‘弥渡红花’(CK)。运用AMMI模型有效地解释了红花品种产量性状的基因型、环境和G·E互作效应。根据产量、稳定性参数及AMMI模型分析结果,高产而又稳定的品种有‘YN1805’和‘YN2057’,高产而又不稳定的品种有‘YN512’和‘YN1959’,不高产也不稳产的品种有‘YN495’、‘YN2527’和‘弥渡红花’(CK)。在红花生产中,应选用产量高、适应性强的品种。
The genotype-environment interaction effect（G·E） determines the stability of crop yield traits in multi-ecological environment. It is important to study the effect of G·E interaction on the petals yield stability of safflower. Randomized block design was used, and 7 safflower varieties, 4 test spots and 3 replicates were selected to determine the petal yield of each variety. The genotype, environment and G·E interaction effects of safflower varieties were analyzed by using AMMI model. The genotype, environment and G·E interaction effect all reached extremely significant level. The genotype point accounted for 15.94% of the total variance, the environmental effect accounted for 16.29%, and G·E interaction effect accounted for 47.64%, indicating that G·E interaction effect on the yield changes was much larger than the effect of genotype and environment. The principal component of the interacted effect calculated the genotype stability parameter（Dg）, which was in the order‘YN1805＇〉‘YN2057＇〉‘YN512＇〉‘YN495＇〉‘YN1959＇〉‘YN2527＇〉‘Midu safflower＇（CK）. The genotype, environment and G·E interaction effect of yield traits of safflower varieties were effectively explained using the AMMI model. According to the results of yield, stability parameter and AMMI model analysis, the varieties with high yield and stability were‘YN1805＇and‘YN2057＇, the varieties with high yield and instability were‘YN512＇,‘YN1959＇and the varieties with low yield and instability were‘YN495＇,‘YN2527＇and‘Midu safflower＇. In safflower production,high yield and adaptable varieties should be used.
