The display of trait of male sterility at interspecific hybrids F1 - F3, BC1 - BC2 of combinations T. kiharae Ulianovka, Ulianovka .kiharae, Mironovskaya 808 T.dicoccum was investigated. Since F1, in all combinations of crossing, annually were sowing a grain under the following scheme: ear with grains from free pollination, ear with grains from compulsory self-pollination and ear with grains from synthetic pollination under by individual parchment isolator. The plants of all families of combinations Triticum kiharae Ulianovka, Ulianovka .kiharae, since F1, were sterile, had structure of anthers such as a tail of swallow and high sterility of pollen, characteristic for trait of cytoplasmic male sterility (CMS). The majority of plants were sterile in F2 and F3, but observed and half-fertile plants. The ears of all plants blossomed was open within 10-17 days, but grains from free pollination the insignificant quantity was setting, as a rule. In combination Mironovskaya 808 T.dicoccum in F1 all plants were half-fertile, and in F2 and F3 were segregated on sterile, half-sterile, fertile and half-fertile forms. The sterile plants blossomed are open during 15 -20 days, anthers had both filamentous form, and form a tail of swallow . Pollen grains in both types of anthers were sterile. According to our researches (Khailenko, 1995), the species .kiharae has trait CMC, but the species T.aestivum (the cultivars Ulianovka and Mironovskaya 808) and T.dicoccum dont have of such trait . Probably, in the investigated combinations of crossing there is a display both trait CMC, and dominant trait of gene male sterility (GMS). The problems of cytoplasmic and gene male sterility at wheat, arising at carrying out of works on the remote hybridization of cereal plants are discussed.
