The results of the effectiveness evaluation of the breeding process on the combination of traits complex in the hybrid posterity of gooseberries from 17 combinations of crosses are given in the article. The research is conducted at the breeding plots of Berry crops department of the Republican Unitary Enterprise "Institute of Fruit growing". The hybrid fund of 1990-91 crossing, including 665 plants from 17 combinations of intervarietal crossing is estimated. As a source of parental forms the Yarowoy, Afrikanets, Masheka gooseberry etc was taken. The nature of inheritance of two, three or more economically useful traits is studied. By results of research of 665 hybrids the 7 plants are selected, that plants combine the traits of high resistance to sphaeroteca and high productivity with big berries of sweet taste; one plant with the combination of all these traits and high height of bush is selected. To create of gooseberry varieties suitable for mechanized harvesting, 19 plants with the highest traits of resistance, productivity and bush's height are selected. Inclusion in the hybridization of two types of derivatives, as Ribes hirtellum and Ribes reclinatum, promotes to receiving of hybrids with 6 studied traits. The varieties and hybrids of gooseberry, derived from two kinds - R. succirubrum and R. reclinatum, Combinations of crossing with the combination of the genetic basis of the three species -R. robusta, R. succirubrum, R. reclinatum and R. robusta, R. hirtellum, R. reclinatum promote to high yield of hybrids suitable for mechanized harvesting. Thus, not all combinations of crossing, selected as prospective combinations in the analysis process of inheritance of individual traits, provided the high production of hybrids with the complex of traits and vice versa. The hibrid's gooseberry families of Belaruskiy Sacharny × Krasnoslavyanskiy, Belaruskiy Krasny × Joselin, 10-45 D × 15-13-10-52u and 10-52D × Yarovoy have the high breeding value.
