Genetic peculiarities of display of the changed forms in inbreded and crossbreded posterities of vegetable plants

Results of researches inbreded and crossbred posterities of vegetable plants (carrot, lettuce) are submitted. It is shown, that display of the changed forms at cross-pollination the plants (carrots) possessing predominant character (light orange painting of a root crop) in a number inbreded posterities from self-pollination of the plants having recessive character (orange painting) is caused by presence in a population of a grade of various genotypes on painting the root crop, containing two predominant genes interacting on type epistasis. At self- pollination plants (lettuce) in the some crossbreded posterities from crossings phenotype close headed plants (recessive character) from population of grade display of leaf forms (predominant character), determined complimentary by interaction of predominant genes and presence in genotypes headed plants of a gene - inhibitor is established.
