Recurrent selection for seed size in soybean. I, Response to selection in replicate populations

Seed size is an important component of soybean [Glycine max (L.) Merr.] yield. The objectives of this experiment were to investigate the response to recurrent mass selection for increased seed size on male-sterile (MS) plants, examine the indirect response on seed size and seed yield of derived male-fertile (MF) plants, and evaluate the repeatability of selection response across replicate populations
