M. Schuster et R. Buttner, CHROMOSOME-NUMBERS IN THE MALUS WILD-SPECIES COLLECTION OF THE GENEBANK DRESDEN-PILLNITZ, Genetic resources and crop evolution, 42(4), 1995, pp. 353-361
212 Genotypes of the Malus wild species collection in Dresden were ana
lysed for their chromosome numbers. The most frequent chromosome numbe
r is 2n=2x=34. Some genotypes are polyploid (2n=3x=51 or 2n=4x=68). Th
e chromosome numbers of the following species are reported for the fir
st time: Malus x arnoldiana 2n=34, M. x dawsoniana, M. x moerlandsii 2
n=34 and M. x sublobata 2n=34, M. trilobata 2n=34, M. tschonoskii 2n=3
