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.
