[Supernumerary chromosomes in the karyotype of the Siberian spruce, P. obovata].

TSitologiia i genetika - 1 Jan 2000

Muratova E N, Vladimirova O S

Abstract excerpt

Results of karyological study of ornamental forms of Picea obovata Ledeb. are presented. Typical chromosome number (2n) is 24, but some trees have one or two additional chromosomes (2n = 24 + 1B; 2n = 24 + 2B). Heritability of additional chromosomes, pollen fertility, morphological features of cones, and seed quality in trees with and without additional chromosomes were studied. System of B-chromosomes is of...
