20份金鱼草种质资源花色性状鉴定与分析

Identification and Analysis of Flower Color Traits of 20 Germplasm Resources of Antirrhinum majus

为分析金鱼草种质花色性状、研制金鱼草新品种测试指南,通过收集种质并开展种植试验,在同一周期内分别对金鱼草花朵多个主要花色相关性状进行观测与鉴定,并将各性状的不同表现进行分类和分级。结果表明:通过比对RHS比色卡将金鱼草种质花朵整体主色分为10类、下唇底座主色分为8类、下唇底座的斑主色分为3类、雄蕊花青甙显色强度分为3级、雌蕊主色分别分为3类。研究发现雄蕊花青甙显色强度、雌蕊主色和雌蕊紫色程度3个性状在种内相对一致、种间具有明显差异,可作为金鱼草指南候选性状。

In order to analyze the flower color traits of Antirrhinum majus germplasm and develop the test guidelines for the new varieties of Antirrhinum majus,by collecting the germplasm and carrying out the planting experiment,several main traits related to the flower color of Antirrhinum majus in the same cycle were observed and identified,and the different performances of each trait were classified and graded.The results showed that by comparing the RHS colorimetric cards,the overall dominant color of Antirrhinum majus germplasm flowers was divided into 10 categories,the dominant color of the labium base was divided into 8 categories,the spot dominant color of the labium base was divided into 3 categories,the color intensity of stamen anthocyanin was divided into 3 levels,and the dominant color of the stamen was divided into 3 categories.It was found that the color intensity of stamen anthocyanin,the dominant color of stamen and the purple degree of stamen were relatively consistent within the species and showed obvious differences among the species,which could be used as the candidate traits for the guide of Antirrhinum majus.
