The genetic resources available for cassava improvement include advanced breeding lines, collected landraces and the crops`s wild relatives. Information about the structure of these gene pools is important in the development of sound germplasm conservation and use strategies. RAPD markers have be...
Seven cattle populations indigenous to East Africa and three reference breeds (Sahiwal, N'Dama and Friesian) were characterized with 18 autosomal microsatellite loci. Within-breed diversity was high in all breeds with observed heterozygosities ranging from 0.511 (+ or -) 0.214 (N'Dama) to 0.660 (...
The paper reviews the limited data available on both between-and within-breed genetic variation for resistance to helminthiasis in cattle, sheep and goats in the tropics. Topics covered include criteria of resistance, resilience or tolerance, parasite species and mode of infection, parameters to ...
Banana (Musa) is one of the most important economic and staple crops in the world. The majority of edible cultivated banana species arises from two species of the Eumusa group, Musa acuminata (A genome) and Musa balbisiana(B genome). In order to assess the biochemical diversity that exists in our...
The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involve mating, for each breed, 150 ewes with 10 rams to lamb at the begi...
