Recombination of some characteristics in fj generation of grapevine

Abstract

To create seedless cultivar with colored juice, with high yield and high fruit quality, the crossing between Evita and Beogradska Besemena cultivars has been done. In the obtained progeny, in addition to the selection of seedlings with expected characteristics recombination, the mode of inheritance has been followed as well. Monogenic inheritance has been determined for the berry skin color and juice color. Exception to monogenic inheritance has been determined for seedlessness. For the grape yield and bunch weight, the dominance of parent with low grape yield and low bunch weight (cv. Evita) have been determined, while for the berry weight the partial dominance of parent with low berry weight (cv. Evita) have been determined. In regard to sugar content of must, positive heterosis has been exhibited. The expected complete recombination of desirable characteristics (seedlessness, colored juice, high yield and high fruit quality) was not shown in any seedling of F1 generation.
