Kravchenko N. Performance and its components interspecsfic hybrids of potato and their offspring

3.The thesis presents the results of research on promising set of complex interspecific hybrids of potato and their phenotypic manifestations beckrosses for performance, its components and determining combinative ability of some of them. On the basis of determining the upper size limits of display characteristics shares interspecific hybrids and their beckrosses with higher expression of performance than the better-class standard of quality benefits of the processed material, stability of expression indexes set high potential of interspecific hybrids on the performance of all bubbles in the nest, or commodity, the average weight of a tuber, or commodity. Respect to each of the processed features optimal methods of selection and creation of forms, the number involved in their creation of species, the degree beckrosses. On the basis of pedigree breeding and valuable color combinations on the basis of parental forms. Determined the loss of material at different stages of seedlings receiving the first year. Calculated in correlation coefficients between the amount of material at each stage. On the basis of the definition of general and specific ability Matching color beckrosses interspecific hybrids with high effects ZKZ and SSI on grounds that were studied.
