利用AMMI模型对大丽花表型性状稳定性的评判
Judgment on Stability of Dahlia Phenotypic Traits by AMMI Model
摘要
Abstract
In order to analyze the stability of dahlia phenotypic traits under different environment, 7 phenotype traits were used to analysed their stability in 3 years(2009 - 2011) with 9 elite dahlia cul-tivars as materials. The results indicated that effects of genotype on leaf length, petiole length and pedicel length were extremely significantly different, but the effects of environment were not significantly different. Other phenotypic traits have significant differences in both effects of genotype and effects of environment. Effects of the genotypes on leaf length, leaf width, petiole length, flower diameter, pedicel length and stem diameter were greater than environment except the effects of environment on plant height. Some traits were analysed by using AMMI model. The result showed that for leaf width,the most stable culti-vars were Bodascious and Pam Howden. The varieties with better stable petiole length included Bodas-cious and Papageno. The cultivars with better stable pedicel length included Hy Enid and Pennsgift. Environment was much more appropriate for leaf width,petiole length and pedicel length in 2009 than that in 2010 and 2011. It is noted that genotype,environment and GXE interaction on phenotype traits can be explained well by using AMMI model,which also selected the cultivars with stable traits.关键词
