Where is yam grown

Identifying yam domestication centres and diverse gene pools are much needed for finding more resilient and higher-yielding varieties in the future.

The scientists identified diploid accessions which clustered according to geographical origin, whilst triploids were mostly from Asia and 34 tetraploid accessions were close to the triploid groups. Further analysis found only 92 independent diploid genotypes from the diploid accessions, suggesting high clonality within this species. There was low genetic richness and negative inbreeding coefficients within continents which are signs of strong domestication bottlenecks.

This global research effort not only revealed the main domestication events but also produced an important dataset of yam genetic diversity. Skip to content Search for: Search Close. Take our quiz and test your root knowledge! Sweetpotatoes are almost always sweeter than yams. They have versatile flavor easily altered by cooking methods.

Starchier and more potato-like, usually not very sweet. Versatile; flavor easily altered by cooking methods. All are more slender in appearance than a potato and have tapered ends; however each of these does have a different flavor profile.

Varies considerably. Some yams are the size and shape of small potatoes; others can grow up to 1. In Malaysia, yams are used in a coconut milk dessert. Planting depth: Plant the tuber a few cm below the soil surface. Plant spacing: Space plants 50 cm apart. Excavate carefully to avoid damaging the skin, start a fair way back from the leaf stem. Tubers can be stored for many months in a cool, dry place. These restrictions are very important as they prevent the spread of plant pests and diseases.

No potatoes, garlic, shallots, strawberries or tubestock can be sent to South Australia. No tubestock can be sent to Northern Territory.
