Cytogenetic Studies of Natural Hybrid, Rubus×hiraseanus, and Artificial Hybrid between R. coreanus and R. parvifolius (Rosaceae)

抄録

This study was carried out to present cytogenetical information on the natural hybrid, 2x R.×hiraseanus, and the artificial hybrids between R. coreanus and R. parvifolius. 2x R.×hiraseanus and artificial hybrids had similar karyotypes, formulated as 2n= 14 = 10m+2sm+2tst. The formation of seven bivalents at M I in almost all PMCs of hybrids indicates that R. coreanus and R. parvifolius are closely related species with similar genomes.
