Breeding biofortified potatoes to relieve micronutrient malnutrition

CIP scientists are developing potatoes with high micronutrient content as part of a broader effort to address micronutrient deficiencies, which disproportionately affect the health of rural women and children. Those efforts have resulted in new potato breeding populations of nutrient-dense candidate varieties with up to 32–45 parts per million (ppm) dry weight iron and 22–37 ppm dry weight zinc, depending … Read More

Genomic research improves scientists’ understanding of cassava diversity and domestication

RTB scientists are using next-generation DNA sequencing data to construct more accurate crop and species phylogenies, or evolutionary histories, shedding new light on the relationships among different populations and between cultivated crops and their wild relatives. This knowledge can help breeders locate new sources of desirable traits, or expand the use of interspecific breeding, and will facilitate marker-assisted selection and … Read More

Unraveling the secrets of yam genomes to improve breeding

Despite yam’s importance as a food security and cash crop, knowledge of its genome lags far behind that of other crops. RTB is helping to bridge this gap through genomic and metabolomic research to better understand yam diversity, and provide breeders with knowledge to accelerate and enhance the development of improved varieties. When RTB began work, no reference genome existed … Read More
