Molecular-genetics analysis of Malus sieversii of Dzhungar population in-situ and ex-situ. Malus sieversii study in Kasakhstan

Malus sieversii is recognized as the main ancestor of the cultivated apple tree and has a valuable gene pool and in the last decades it is endangered in Kazakhstan. The genetic diversity of 13 sort-clones of Sievers apple tree of the Dzungarian population of The Main botanical garden’s introduction collection in Almaty (Kazakhstan) and 31 samples from three populations was assessed using 8 polymorphic ISSR markers, the phylogenetic relationship of the clone varieties with the natural population was estimated using ribosomal and chloroplast DNA.
