Hybridization, missing wild ancestors and the domestication of cultivated diploid bananas.

Hybridization and introgressions are important evolutionary forces in plants. They contribute to the domestication of many species, including understudied clonal crops. Here, we examine their role in the domestication of a clonal crop of outmost importance, banana ( ssp.

Maximizing genetic representation in seed collections from populations of self and cross-pollinated banana wild relatives.

Background: Conservation of plant genetic resources, including the wild relatives of crops, plays an important and well recognised role in addressing some of the key challenges faced by humanity and the planet including ending hunger and biodiversity loss. However, the genetic diversity and representativeness of ex situ collections, especially that contained in seed collections, is often unknown. This limits meaningful assessments against conservation targets, impairs targeting of future collecting and limits their use.

Challenges for Ex Situ Conservation of Wild Bananas: Seeds Collected in Papua New Guinea Have Variable Levels of Desiccation Tolerance.

Ex situ seed conservation of banana crop wild relatives ( spp. L.), is constrained by critical knowledge gaps in their storage and germination behaviour.
