The collection of Phaseolus of the CIAT Genetic Resources Unit reached a total of 34,312 accessions in 1984. Of these, 89.0 percent corresponds to P. vulgaris, 7.0 percent to P. lunatus, 3.5 percent to P. coccineus, 0.6 percent to P. acutifolius, and 0.2 percent to wild noncultivated species. An ...

This publications provides an approach by which conservationists can determine whether or not long-term seed storage is feasible for a particular species, i.e. whether or not that species shows orthodox seed storage behaviour. It provides advice on the implementation of the protocol, examples of ...

The regeneration of germplasm resources is an integral part of the conservation programme. This study is directed towards the strategy and tactics of seed regeneration and multiplication by sexual reproduction in relation to problems of maintaining the genetic constitution of the original sampled...

Sustainable Development Goals 5 calls for addressing gender equality and women empowerment by, among other things, eliminating all forms of discrimination against women. At CIP we interpret this to mean strengthening the use of gender approaches in research and ensuring that research products are...

Virus‐related degeneration constrains production of quality sweet potato seed, especially under open field conditions. Once in the open, virus‐indexed seed is prone to virus infection leading to decline in performance. Insect‐proof net tunnels have been proven to reduce virus infection under rese...


Ogero, K.O.Kreuze, J.F.Mcewan, M.A.Luambano, N.D.Bachwenkizi, H.Garrett, K.A.Andersen, K.F.Thomas-Sharma, SaraVlugt, R.A.A.[Efficiency of insect‐proof net tunnels in reducing virus‐related seed degeneration in sweet potato.]Efficiency of insect‐proof net tunnels in reducing virus‐related seed degeneration in sweet potato.

This handbook provides an introduction to seed storage physiology for those responsible for plant genetic conservation and a selective summary of the literature on seed survival in storage, and thus on seed storage behaviour, for over 7000 species from 251 families. Part IA summarizes progress in...

Cowpea is a multipurpose pulse crop grown by poor farmers in marginal and drought prone areas of Ethiopia. Information on the extent of genetic variation in cowpea genotypes is crucial to identify diverse genotypes for crop improvement and for efficient utilization of the existing genetic resourc...
