The use of marker-assisted selection in developing improved varieties of soybean

Description

Marker-assisted selection (MAS) for soybean improvement is based on over two thousand mapped loci. In genetics databases there are thousands of mapped loci that underlie quantitative traits, oligogenic traits and simple traits. This chapter describes examples of methods for developing and using DNA markers derived from genomic sequences for monogeneic, oligogeneic and polygeneic traits, together with examples of successful mapping, fine mapping and gene isolation. The chapter examines ways in which marker-assisted selection can be used to isolate and select desirable traits in soybeans.
