A ddRADseq Survey of the Genetic Diversity of Rye (<i>Secale cereale</i> L.) Landraces from the Western Alps Reveals the Progressive Reduction of the Local Gene Pool

Rye (<i>Secale cereale</i> L.) has been at the basis of agriculture for centuries in most mountainous and northern areas of Eurasia, because it is more resistant than other cereals to low temperatures and poor soils. Rye deserves to be re-evaluated as a source of “environmentally resilie...
