Biodiversity of East Asian apple-tree species and their use in breeding

Maikop Experiment Station of VIR maintains and studies the richest genetic diversity primitive East Asian apple-tree species, including sections Docyniopsis C.C. Schneid. Sorbomalus Zabel. In addition, research covers species Gymnomeles Koehne section, more advanced in evolutionary development, which, addition to Siberia Far East, are also spread China, Mongolia other regions Asia. The collection is studied according VIR’s guidelines. section represented by one oldest Malus spp. – M. sikkimensis (Wenz.) Koehne, inhabiting Eastern Himalayas. Accession k-2412 characterized high yield, disease resistance, late flowering. contains 5 main 6 hybrid ones, belonging various series section. Toringonae (Rehd.) Lang. includes sieboldii (Regel) Rehd., Japan, Korea. Of two accessions this most promising k-43201, with a annual early start fruiting, resistance diseases. same several obtained participation . well-known them × floribunda Sieb. Great prospects for breeding observed sargentii Rehd. k-2428 short stem, ornamental traits and, long-term data, stable immunity harbors broad from Among them, there set valuable traits, etc. hupehensis (Pamp.)
