Evaluation and classification of leaflet shape and size in wild soybean.(Plant Genetic Resources)

Crop Science, March, 2004 by Chen, Yiwu; Nelson, Randall L.

Two gene pairs are known to affect leaflet shape in soybean [Glycine max (L.) Merr.], but only two categories of leaflet shape are routinely used to characterize soybean germplasm. Very little information has been published about leaflet shape and size for wild soybean (Glycine soja Sieb. & Zucc.) accessions in the USDA Soybean Germplasm Collection but these characteristics have been shown to be among the most diverse morphological traits in the Chinese G. soja collection. The objectives of this research are to evaluate and establish a visual classification system for the variation of leaflet shape and size in the USDA Soybean Germplasm Collection. In 1998 and 1999, 661 wild soybean accessions from the USDA Soybean Germplasm Collection in maturity groups 000 through IX were grown...
