Simultaneous investigations were conducted at experiment farms at Fort Valley State College and Maryland Eastern Shore in 1985 with 42 soybean genotypes (14 each from MG III, IV, and V) to determine seed yield efficiency (SYE) and grain yield and their relationship to other agronomic traits. The mean seed yield efficiency ranged from 34 to 51, 35 to 50, and 28 to 59% for MG III, IV, and V, respectively. The mean grain yield for three MGs was similar and ranged from 19.65 (MG III) to 22.86 (MG V) quintals/ha.
