Peculiarities of geneatogic influence of producer-bulls, used in breed creation process, of red-motley Holstein, Angler, and red Danish varieties on red steppe cows have been analyzed. Productive qualities of parents and their young during the firs lactation have been compared. The generated central zone type of red dairy breed has sufficient branching on separate structural subtypes with expressed a phenotype features, for the subsequent development and perfection. By results of the previous researches it is established that in holstein type the greatest distribution was got with genealogic line Reflekshn Sovering 198998. From bulls of this line 7 related groups and 12 branches which structure includes 36 sires are generated. From genealogic line Reflekshn Sofrina Sovrins 98998 new factory line Rigela 4939 is allocated. Mother of the founder differed high efficiency (11239 kg of milk with the content of fat of 4,3 % are milked from it for lactation in its 11 years). From genealogic line Montvik Chiftein 95679 the most numerous by quantity of sires establishment line Khanovera 162931/9172 is allocated (which were used in Dnepropetrovsk region). Its structure includes 7 branches and 54 bulls. High dairy efficiency of descendants of sires of Reps 401200, Mobi 378905, Difens 398831 allows to plan their use in individual attaching bull-productive group to cows for reception of continuers. Line Siling Trajdzhun Rokita 252803 is presented by three related groups: Rokit Kemp 302981, Ekmi 98 and R.Starlajt 308691. Group Erlauhta 17390 which is allocated from line Frema 17291 is perspective
