Abstract: In the middle early synthetic population 1/2003 the first cycle of recurrent selection for increasing of Combining Ability with recurrent parent the inbred line XM 4390 was finished. The 10 of total 168 testcrosses tested in the field trials, are sowed in the breeding nursery for self pollination and selection. 47 progenies with the best results are mixed for second cycle of recurrent selection.
