Montvid P. Egg-plant F1 ontogenetical suitability, transforming function of meiosis and spectrum of genotypic variability in F2

The object is correlation between ontogenetical suitability of F1 heterosygotes and genotypical variability spectrum in F2; the aim is to determine ontogenetical fitness of F1 hybrids influence to indicies that characterised transformation of genetical information in the meiosis and genotypical variability spectrum in F2; the methods are the method of genotypical variability spectrum in F2 prognosis, cytological, cytobiophisical, the method of field experiment, statistical methods; the new approach - for the first time there are determined peculiarities of meiosis transforming function in egg-plant F1 hybrids with different ontogenetical fitness; the results - the method of increase the level of recombination and spectrum of genotypical variability is offered; the field is egg-plant breeding
