摘要:

通过对切花菊品种神马与深志杂交F1代群体的叶长、叶宽等19个叶片数量性状及12个叶形结构参数的测量和统计分析,研究切花菊叶片数量性状的遗传与变异特性。结果表明,切花菊杂交F1代群体叶形分离广泛,19个数量性状和12个叶形结构参数的变异系数差异较大,其中左上裂片长的变异系数最大(37.72%),叶最宽处所在位置/叶长的变异系数最小(10.79%)。4个方位(左上、左下、右上、右下)裂片长的变异系数均大于对应裂片宽和叶脉长的变异系数,4个方位(左上、左下、右上、右下)裂片长/裂片宽的变异系数均大于对应裂片长/叶脉长的变异系数。F1代群体的叶长/叶宽、顶裂片长/叶长、顶裂片长/顶裂片宽和右下裂片长/右下裂片宽等平均值较亲本中值呈减小趋势。叶长与叶最宽处所在位置呈极显著正相关(相关系数为0.815),叶长与叶柄长/叶长呈极显著负相关(相关系数为-0.532)。本研究结果可为切花菊叶片性状的遗传特性和新品种选育提供理论基础。

Abstract:

In order to analyze genetic and variation characteristics of leaf quantitative traits in Chrysanthemum morifolium, Jinba×Fucashi cross combination and F1 offspring population were selected, 19 quantitative traits (eg. leaf length, leaf width) and 12 structural parameters of leaf were measured and statistically analyzed. The results showed that the leaf morphology was widely separated in the F1 offspring population, with diverse changes in variation coefficient in 19 quantitative traits and 12 structural parameters of leaf. The variation coefficient of length of upper left lobe was the highest (37.72%), the variation coefficient of location of the widest part of the leaf/leaf length was the lowest (10.79%). The variation coefficient for the lobe length in the four orientations (upper left, lower left, upper right, and lower right) was greater than the variation coefficient for the corresponding lobe width and the leaf vein length, while the variation coefficient of lobe length/lobe width in four orientations (upper left, lower left, upper right, lower right) was greater than the variation coefficient of the corresponding lobe length/leaf vein length. The average values of leaf length/leaf width, apical lobe length/leaf length, apical lobe length/apical lobe width, and lobe length/lobe width in lower right in the F1 offspring population showed a certain decreasing trend compared with the median of the parents. There was an extremely significant positive correlation between leaf length and the location of the widest part of the leaf (correlation coefficient was 0.815), and an extremely significant negative correlation between leaf length and petiole length/leaf length (correlation coefficient was -0.532). The results provided a theoretical basis for analysis of leaf genetic traits and breeding of new varieties of Chrysanthemum morifolium.
