三色堇不同品种观赏性状的比较与评价

对三色堇品种观赏性状的比较和评价是其合理利用的基础。在对12个三色堇品种8个观赏性状调查的基础上,分别对不同品种在各观赏性状上的差异进行了比较和评价,最后采用百分制评比法对各品种进行了综合评价。结果表明:7、6、12、3号品种为双色和三色花,花色观赏性高;3、2、1、11、9号花径最大,大花优势明显;12、7、10号的花数最多,多花优势明显;10、7号冠幅大、分枝性强,丰满度好;开花指数以9号最高,其次为3、2、1号;8、10、7、4号株高适中;11、7、10号冠幅/株高大,株型较为理想。将12个品种总体评价依次分为:优(7号和10号)、良(12、9、3、2、1号)、中(8、6、5、4、11号)3级。

Comparison and Evaluation on Ornamental Traits of Different Pansy (Viola tricolor L.) Cultivars

Comparison and evaluation on ornamental traits of pansy cultivars are the basis of reasonable application.This experiment was carried out to investigate and analysis 8 ornamental traits of 12 pansy cultivars for their ornamental evaluation.The results showed that:No.7,No.6,No.12 and No.3,with double-color and three-color,have the highest appreciation;No.3,No.2,No.1,No.11 and No.9,with the largest flower diameter,have the apparent ornamental advantages for their bigger flowers.No.12,No.7 and No.10 have advantages for their many flowers;No.10 and No.7 have the widest crown diameter and the more branches,showing fullness in flowerpot;the highest flowering index is No.9,followed by No.3,No.2 and No.1;the plant height of No.8,No.10,No.7 and No.4 are medium;the crown/height of No.11 and No.7 and No.10 were higher,showing idea plant type.All of the 12 varieties tested are falled into three grades,the best (No.7 and No.10),better (No.12,No.9,No.3,No.2,No.1),and good (No.8,No.6,No.5,No.4,No.11).Finally,the application of radioactive breeding on pansy ornamental improvement was discussed.
