Leaf Shape Variation and Its Correlation to Phenotypic Traits of Soybean in Northeast China
Leaves are the main plant organs which play an important role in plants life.Soybean, as a major legume crop, has diverse leaf shapes among its genotypes.The motivation of this study is to analyze the leaf shape variety of 206 soybean genotypes from northeast China and its correlation to other phenotypic traits.Morphological operations have been adopted to extract the features of leaves.The results show significant differences of phenotypic traits among leaf shape groups, which indicate that the lanceolate leaf group has the highest mean plant height (89.62 cm) and the largest number of nodes per plant (15.72 nodes/plant);the round leaf group has the lowest mean 100-seed weight (18.14 g) and seed weight per plant (17.92 g);the lowest mean number of pods (41.86 pods/plant) is in the elliptical group.In terms of the maturity period, most of the lanceolate leaves (67.24%) belong to the late maturity group, in which there are only few of the elliptical leaves (11.54%).Our results suggest that the variation in leaf shape is an important indicator of other phenotypic characteristics, which could provide more information for soybean classification, as well as for cultivating new varieties in northeast China.
