Abstract
Small, medium and large seed sizes of the groundnut genotypes Spancross (a released variety) and 2/91 (a breeding line) were assessed for growth and yield under field conditions in 1996 and 1997. In 1997, there were significant effects of cultivar and seed size on shoot and root biomass. The shoot diy matter for large seeds was 36% and 24% greater than for small seeds of Spancross and 2/91 respectively. Large seeds of 2/91 showed a significant increase of 26% in root biomass but Spancross recorded a decline of 8% over small
seeds. Generally, productivity increased with seed size. In 1996, rainfall was low and varietal differences were significant, with 2/91 giving significantly higher kernel yields (2082 kg/ha) than Spancross (1498 kg/ha) when averaged across seed size.
