The combination of various directions in selection provides creation of varieties with a complex of properties and the signs possessing high productivity adapted to certain soil, climatic and economic conditions. In selection practice with citrus fruit crops for reception of hybrid seeds following main principles are considered: characterical, geographical. Characterical a principle in selection work with tangerine (Citrus reticulata Blan. var. unchiu Tan.) Allows to be based on use of sources selection-significant signs - productivity, low-growing, biotical and abiotical stability, the complex maintenance components of biochemical structure, the estimation of initial forms is spent on phenotype. Geographical principle in tangerine selection has wide application it is based on application of interpatrimonial and interspecific hybridization. Use of wild, half-civilized and cultural relatives of citrus allows to receive hybrids with the big spectrum of variability to the important signs (early naturity, fast maturing of fruits, large fruits). 47 combinations of crossing were analyzed and allocated 21 - perspective for creation of hybrid fund of a tangerine where parent forms “Kowano-Wase”, “Miyagawa Wase”, “Yubileinii” - transfer to the posterity such signs as - low-growing, early naturity, productivity, quality of fruits. Relatives and hybrid kinds of citrus C. ? tangelo, С ? clementina, C. ? leiocarpa, C. ? insitorum, P. trifoliata, hybrid 3252 transfer winter hardiness, large fruits. The most productive combinations on an exit winter-hardy seedlings are crossings “Miyagawa Wase” ? P. trifoliata, “Kowano-Wase”? P. trifoliata and “Kowano-Wase”? C.? insitorum. The greatest exit of undersized seedlings is noted in combinations with participation in quality pollinator C. leiocarpa. In combinations “Yubileinii” ? C.? insitorum, “Yubileinii” ? hybrid 3252, “Miyagawa Wase” ? C.?insitorum the greatest quantity early naturity forms is allocated. Large fruits are transfer to posterity fatherly forms C. ? insitorum, С sinensis “Valencia”’.
