Four of the many Ethiopian sheep breeds are described. These four breeds have evolved in different ecological zones, the Adal and the Somali Blackhead breeds in the lowland up to an altitude of 1100m, the Horro in the middle altitude from 1400 to 2000m, and the Menz in altitudes higher than 2500 ...

Amblystira machalana Drake (Chinche negro de encaje) es una plaga del follaje de la yuca, que se ha venido observando desde 1985 en diferentes partes de Colombia, Ecuador y Venezuela provocando daños en este cultivo. Varios trabajos se realizaron en el CIAT con el objeto de conocer su ciclo de vi...

Research aimed at developing various Stylosanthes species as forage crops in South America began with the collection of Brazilian germplasm in the 1960s. These efforts have intensified greatly in the past 25 years with the participation of a number of local, national and international institution...

Ethiopia is cited as one of the centres of sorghum diversity. In order to assess the on-farm genetic resources management of sorghum various research methodologies were employed. These were focus group interviews with 360 farmers, key informant interviews with 60 farmers and development agents an...

A total of 44 bean (Phaseolus vulgaris L.) genotypes was evaluated for disease reactions to bean golden mosaic virus (BGMV) by mechanical and whitefly inoculation under glasshouse and field conditions, respectively. Most of the genotypes reacted similarly under both screening conditions, with a f...
