Yields of potato hybrids F <sub>1</sub>C <sub>2</sub>
The potato hybrids of F 1C 3 accumulate much more quantity of a biomass under identical conditions of cultivation on comparison with a standard grade the Cardinal. On general and economic (tubers) of efficiency hybrids F 1C 2 exceed the standard of the variety Cardinal in ones and a half - two times. In particular the general crop of a biomass at hybrids F 1C 2 of a potato fluctuates from 45 to 110 t \hectare, against this indicator at the variety Cardinal – 37 t \hectare. Such law is observed and on the basis of an economic crop (a crop of tubers) hybrids F 1C 2. At potato hybrids the economic crop fluctuates in a range – 40-71 t/hectare, and the variety Cardinal it makes 30t/hectare that it on 33-136 % is less in comparison with hybrids F 1C 2 of potato. Allocated new hybrid lines F 1C 2 of potato are of interest for the further breeding works.
