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...

IBPGR-CIAT Collaborative Project on a pilot in vitro active genebank
For many crops with preferential vegetative propagation, or which are sterile, or have seed unresponsive to standard seed storage techniques, in vitro methods can provide a valuable adjunct to other germplasm conservation strategies. Two types of in vitro gene banks are proposed: (i) an in vitro ...

In vitro methods of germ-plasm conservation
Hybridization of synthetic allotetraploids of S. pinnatisectum with S. etuberosum (4x-EP) with S. acaule (2n = 4x = 48) resulted in two individuals that were highly fertile, in contrast to all other progenies. The unique individuals are hexaploids, 2n = 72, while the other progenies are tetraploi...

Application of interspecific sesquiploidy to introgression of PLRV resistance from non-tuber-bearing Solanum tuberosum to cultivated potato germplasm
In vitro conservation strategies are reviewed, with special reference to in vitro active and basic gene banks; likewise, important aspects that should be considered for in vitro conservation, such as regeneration, viability, genetic stability, and information systematization, are discussed. The 2...
