摘要：对34个中原牡丹传统品种的6个定性二元性状、21个定性多态性状和8个数量性状进行连续两年田间观测,并进行特异性、一致性和稳定性分析。结果表明,牡丹传统品种定性二元性状和定性多态性状的一致性均较好,而数量性状因受环境因素影响一致性差;所有品种大部分定性二元性状和定性多态性状表现稳定性较好,数量性状变异最大;经分析筛选出5个定性二元性状和19个定性多态性状用于品种特异性比较和遗传多样性分析。
By conducting a two-year open field observation, six qualitative binary characters, 21 qualitative polymorphic characters and eight quantitative characters of 34 traditional cultivars of Paeonia suffruticosa Andr were analyzed, in terms of their distinctness, uniformity and stability. The results showed that qualitative binary and qualitative polymorphic characters of all the culUvars displayed good uniformity, while there was a lack of uniformity in the quantitative characters due to the influence of environment factors. Most cultivars showed satisfying stability of their qualitative characters but the variation of quantitative characters was significant. Five qualitative binary characters and 19 qualitative polymorphic characters were screened for the comparison of cultivars distinctness and the analysis of genetic diversities.
