SADCC [Southern African Development Coordination Conference]/ICRISAT Regional Groundnut Improvement Program's objectives are to develop germplasm adapted to the varied agroecological requirements of the region. Emphasis is placed on breeding for resistance to early leaf spot (Cercospora arachidicola) and groundnut rosette virus (GRV), as well as breeding for high yield, quality, and earliness. Hybridization was carried out using known sources of resistance to GRV as well as genotypes having the ability to retain their leaves longer under severe early leaf spot pressure. Breeding lines are evaluated in preliminary and advanced yield trials before the most promising material is selected for evaluation in SADCC cooperative regional trials. The program also conducts preliminary and international trials coordinated by ICRISAT Center. The results of the 1985/86 and 1986/87 regional trials are reported. Many entries exhibited yield consistencies across locations. Entry ICGMS 42 performed well
