12份三色堇优良株系主要观赏性状评价

The evaluation of main ornamental characteristics among 12 kinds of pansy

以12份三色堇优良株系为材料,对其花色、花斑、花径、花数和分枝数进行了观测,并进行分析.结果表明：供试材料中花瓣颜色红色成分多,绿色成分少,其中7份材料黄色成分多,蓝色成分少;花瓣的彩度c＊介于3.98~82.53之间,表明花瓣的颜色较丰富;花径在28.52~62.73 mm之间,涵盖大中小3种花型;花数与分枝数随花径的增大而减小.综合所测试的5项指标,测试材料中大花类型的EYO-1、中花类型的HAR2-1、小花型的DFM-11表现最为突出,可以作为今后育种的优良株系.

With 12 excellent plant strain pansy as material,the color,piebald,flower diameter,flower number and branch number were observed and analyzed.The results showed that on the petal color, the red components was more and the green components was less,the composition of yellow was more and the blue components was less in 7 sets; The degrees c＊ of petal color was from 3.98 to 82.53,and showed that the color of the petals was rich;Flower diameter was from 28.52 to 62.73 mm,and covered big,middle,small three pattern.Flower number and branch number decreased with the increase of flower diameter.Comprehensive test by the five indicators,the EYO-1 in the big flower types,the HAR2-1 in the middle flower types and DFM-11 in the small flower types were the most outstanding ones for the tested materials,and can be used as good strain breeding in the future.
