Резюме: After conducting a reciprocal recurrent selection for increasing Combining Ability in a population “Exotic” and completed four cycles of selection the results of testing are analyzed and evaluated. Based on an assessment of the stability of the yield of these crosses the synthetic population E-07 was formed. The some one is included in a new breeding program with direction early flowering. During the 2008 – 2011 year the first cycle of the selection was conducted and finished. As a result of the recurrent selection the improved synthetic sillk average with two days earlier than the base synthetic, and the moisture of the grain was lowered with 4.2%.
