USE MEIOTIC POLYPLOIDY IN CREATION OF THE INITIAL MATERIAL OF THE POTATO
Abstract
Influence method of transfer the perspective diploid hybrids to the tetraploid level (unilateral or bilateral polyploidy) and influence backcrosses B1 and B2 on the economic signs of hybrid offspring are present in article. Established that efficiency, the maintenance of starch, roadworthy for technical processing, stability to fitophtora, amount of tubers, tubers shape, habits, length of stolons, compact tubers pocket at meiotic hybrids is independent of the transfer diploid samples to the tetraploid level. These parameters are caused combination ability of the parental forms.
Backcrosses are different from meiotic tetraploid at reduction amounts of undesirable signs typical of wild potato species. Decreasing of starch at posterity is negative consequence backcrossing. Also is noted reduction in the productivity, reduction of stability to fitophtora, deterioration of roadworthy for technical processing.
