Abstract

Hard seededness in soybean [Glycine max (L.) Merr.] is a quantitative trait that affects the germination rate, viability, and quality of stored seeds. We have used 72 restriction fragment length polymorphisms (RFLPs) to identify genomic regions containing quantitative trait loci (QTL) affecting hard seededness in a segregating population from a G. max by a Glycine soja (Sieb. & Zucc.) cross. Five independent RFLP markers were found to be associated with variation in the hard-seeded trait. These markers and the epistatic interactions between them explain 71% of the variation for hard seededness. A genomic region associated with the i locus accounted for 32% of the variation in this segregating population. This study illustrates one approach to physiological genetic studies in plants.
