Allopolyploidy as possible way of cowberry small (vaccinium vitis-idaea l. Var. Minus lodd) origin

Abstract

The article sets out the theoretical conclusions obtained by comparing the morphological parameters of experimental F1 hybrid (lingonberry (Vaccinium vitis-idaea L.) ? cranberry (Oxycoccus palustris Pers.)) and plant identified in the flora of Magadan initially named as «cranberry small». According to our hypothesis the plant in the Magadan characterized as V. vitis-idaea L. var. minus Lodd. (2n = 24) was the result of natural hybridization having similar time of seasonal development primary diploids (dihaploids) V. vitis-idaea and O. microcarpus (x = 6, 2 n = 12) and the subsequent spontaneous polyploidy arising hybrid.
