Abstract

These days, the selection of grapes with the purpose of obtaining new initial polyploidy material is done with various inductions of mitotic genomic mutations with the help of colchicine and other mutagens. Duration and complexity of the selection process called for a new method that would increase efficiency and accelerate selection of polyploid forms of grapes.The article describes the impact of various concentration of colchicine aqueous solution during inflorescence at meiosis stage of 3 grape cultivars. The study revealed that mutational efficiency constitutes 2.2-28.0%. This is a new technique for the receipt of meiosis of genomic mutations at meiosis stage in grapes. Behaved cyto-anatomical and histological analysis of polyploid mutant forms of grapes. Revealed cytogenetic and histological mutational variation in forms. Genetic analysis of variability is given.

Keywords: Autotetraploids induced polyploidy; Meiosis; Mitosis; Gametes; Hromosom histology; Anatomy; Cytology
