Cytogenetic studies on four almond subgenera

To study the relationship between four wild and domestic species of almond and peach, the karyosystematic studies on the Amygdalus communis L., A. trichamygdalus woronow, A. lycioides spach and Prunus persica L. were performed. Root meristem cells were used for the studies. Ten suitable metaphase plates per specimen were selected and photographed. Parameters such as total length of the chromosomes, long arm length, short arm length, and relative length of the arms were estimated. There were significant differences between the studied species. All of the studied species were diploid (2n=16). Average size of the chromosomes in the studied species of this genus was 2.43± 0.03 micrometer. Also according to the estimated cytological characteristics, A. communis L. was simila to A.lycioides and A.trichamygdalus Woronow, and Prunus persica L were highly similar. Finally, the studied species were classified into two groups based on the cytological characteristics.
