Description
The analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen

GENETIC METHODS OF AUTOPOLYPLOIDY OF GRAPES
06.00.00 Agricultural sciences
Description
There are materials about different genetic methods of metotical and meyotic autopolyploid of grapes in the article. Main morphodiagnostical signs of autopolyploids in it are pointed. New forms and varieties of grape may easily form with the help of genomic mutation. The experimental polyploid on grape leads to functional changes, which helps to become aliveness and stable in bad environment. The increasing of such kind of main genetic signs in grape, as high stable to bad ecological facts, illness and insects, high growing, seedless, high productive from bush, becoming sugar gather in fruits and bioactive elements in juice, etc., so it is possible to solve it only in moving to the new level of ploidy
