Diploid Parthenogenesis Induction in Fragaria vesca L.

S. O. Baturin
Pages: 987–991

Abstract

The paper presents the results of unreduced egg-cell parthenogenetic development induction by intergeneric pollination in different ecotypes of  Fragaria vesca L. (2n = 2x = 14). Parthenogenetic seedlings had the same chromosome number as the mother plant did. We revealed various levels of tendency to pseudogamic diploid parthenogenesis among the specimens of F. vesca. Wild specimens less tend to the phenomenon of parthenogenesis than cultural ones (Alexandria variety) do. For F. vesca under the climatic conditions of West Siberia, diploid parthenogenesis is the facultative additive insuring mechanism of seed-forming which is realized in case of problems with pollination or fertilization.
