Which varieties of roots, tubers, and bananas do farmers and other users want in Africa, and how can breeding programs meet their needs better?

to specific targets for breeders who can then meet their needs”.   This review zoomed in on the adoption of new varieties in some key countries: bananas in Uganda, cassava in Nigeria, potato in Kenya, sweetpotato in Uganda and yam s in Côte d’Ivoire. The review explored three hypotheses on drivers of varietal change.   The first hypothesis, that insufficient priority is given to consumer-preferred characteristics and traits by breeding programs, was confirmed, which helps to explain the limited uptake of modern[…]

Harnessing the power of metabolomics to speed and improve breeding

in the mature plant – the roots, tubers and bananas. Six publications to date have shown remarkable progress. The analysis of leaf and tuber material in different yam species (Dioscorea spp.) identified a subset of metabolites which allowed accurate species classification and highlighted the potential of predicting tuber composition from leaf profiles, based on the[…]

Roots, tubers and bananas key ingredients of a more sustainable food future

Glaszmann points out that traditional breeding of the vegetatively propagated RTB crops is “complex and slow,” which also makes them unattractive to private companies. Cassava, sweetpotato and yam are among the 22 orphan crops that the WRI report says would benefit from extra attention. If the yield of these orphan crops could be increased to[…]

Chilling out for conservation

the long-term conservation of crops that cannot be conserved as seeds, because they are vegetatively propagated or have recalcitrant seeds. Some well-known examples are potato, sweetpotato, banana, yam, cassava, taro and garlic. Such crops are most often conserved as live plants in the field or in vitro, but this makes them particularly vulnerable to contamination or[…]
