Breeding Lines
Potato and Sweetpotato Breeding Lines
In addition to the large genetically diverse in trust collection of potato, sweetpotato, and ARTCs plant material that is conserved in the CIP-Genebank, we also maintain and conserve potato and sweetpotato breeding lines. The maintenance and distribution of these breeding lines is a critical resource for the breeders and other researchers worldwide.
Strategic Agronomic Trait Sources
These are conserved and distributed as in vitro clones to requestors worldwide. These clones are sources of important agronomic traits for the development of new varieties to adapt to climate change, consumer demands, increased food security, nutrition, and enhance income for poor farmers.
Distribution & Legal Framework
These accessions are designated as PGRFA_under development (PGRFA_ud) and are distributed with a Standard Material Transfer Agreement (SMTA) and additional terms based on the intended use.
Notable Accessions in the Breeding Lines Collection
- "DMDD" In Vitro Potato Mapping Population: Used to construct a genetic linkage map for anchoring the potato reference genome sequence. This population segregates for ~150 traits including yield, mineral content, abiotic stress tolerance, as well as various morphological traits (flower, fruit, leaf, stem, and tuber traits). The progenitors and the progeny are also available for international distribution.
- Enhanced Nutrient Potato Population: Developed for enhanced nutrient levels such as colored flesh (high in anthocyanin and antioxidants).
- Biofortified Potato Populations: Developed for biofortification with high content of iron, zinc, and vitamin C.
- Sweetpotato Mapping Population: Specialized genetic mapping population for sweetpotato trait evaluation.
- Germplasm Subsets (Nurseries): Subsets of germplasm containing breeding lines preselected for particular attributes, accessible through the International Nursery Request System.
