Soybean (Glycine max [L.] Merr.) breeders are constantly searching for plant traits that are associated with high seed yield. Breeders have made use of correlated responses in the selection procedures for high yield and disease resistance, high protein and low oil content, and days to maturity and seed yield. Several plant traits such as lodging, plant height, shattering, maturity, etc. must be simultaneously taken into consideration in the selection process.
