Growth, coppicing, and biomass production was compared of 17 accessions of Leucaena leucocephala widely distributed for planting in East and Southern Africa by National Tree Seed Centres in Malawi, Tanzania, Zambia and Kenya. A widely used accession in alley cropping in West Africa was also included. Seed origins were sites in Malawi, Zambia, Nigeria, Kenya and Tanzania. The trial was established in 1989 on a sandy loam soil in a subhumid unimodal rainfall area at Makoka, Malawi. Assessments were done for survival at 3 months, and at 15 and 30 months after establishment for height, diameter at the root collar, number of branches and biomass production. Survival was generally good for most accessions (>90%) with the exception of an accession from Machakos, Kenya (No. 84511) which had a survival of only 67%. Fifteen months after establishment, accessions from Yimbo (Kenya), and 2 K8 accessions from Kasama (Zambia) and Machakos (Kenya) achieved the best height (>3.2 m). Poor accessions included No. 84511 from Machakos (Kenya), Peru (ex. Makoka, Malawi), and the West African accession from IITA (Nigeria) whose height was
