Island populations are often thought to be more susceptible to the loss of genetic diversity as a consequence of limited population size and genetic drift, greater susceptibility to detrimental stochastic events and low levels of immigration. Howe...

Mango (Mangifera indica) is believed to have evolved in a large area spanning northeastern India, Bangladesh, and northwestern Myanmar. We compared the genetic structure of mango accessions from Myanmar with that of mango accessions from Florida, ...

Genetic diversity and genetic integrity were tested for wheat (Triticum aestivum L.) landraces conserved in two gene banks with considerably different germplasm management systems. We identifi ed two sets of 17 wheat accessions derived from identi...

The Potato Genome
Swarup Kumar Chakrabarti, Conghua Xie, Jagesh Kumar Tiwari (Eds.) (Part:Joint Work, Potato Genetic Resources)
Springer International Publishing   Jan 2018   ISBN:978-3-319-66133-9
A very narrow genetic base of cultivated potato has permitted the collection and conservation of its landraces and wild relatives as sources of resistant and agronomically desirable traits. Despite its importance for identifying genetic materials ...
