The overall and specific objectives of a collaborative research project between the International Board for Plant Genetic Resources (IBPGR) and CIAT are given. The overall objective is to assess and demonstrate the technical and logistic aspects of establishing and operating a pilot in vitro acti...

Sesbania have multifarious utilization, and in many instances growth rate is one of the most important criteria for the selection of suitable Sesbania. This paper reports results of a study on the growth rates of Sesbania on two acid soils both low in available P, but one with toxic levels of Al....

Conservation of germplasm has traditionally relied to a large extent on storage of seeds in genebanks. However, some forage species may take a long time to research maturity and produce seeds or, in the case of grasses, have inadequate production of seeds for collection, multiplication, dissemina...

Although lablab (Lablab purpureus L.) is grown in many parts of Africa relatively little investigation has been done on its adaptation to acid soils, which are generally low in available In the present study, lablab was evaluated for tolerance to acidity and low available P on two Ethiopian soils...

The conservation status of wild Arachis spp. is not well characterized for its maintenance and possible future exploitation for the improvement of cultivated peanut, Arachis hypogaea L. Our objectives were to use 2175 georeferenced observations of wild peanut (Arachis spp.) to assess the conserva...

Distinguishing yam species based on morphological traits is extremely difficult and unreliable, posing a challenge to breeders and genebank curators. Development of a molecular assay based on DNA barcoding can facilitate rapid and accurate identification of important Dioscorea species. To develop...

Cassava (Manihot esculenta (L.) Crantz) is a starchy root crop cultivated in the tropics for fresh consumption and commercial processing. Dry matter content and micronutrient density, particularly of provitamin A, traits that are negatively correlated, are among the primary selection objectives i...
