The hybrid fund of 574 plants of gooseberry from 20 combinations of convergent crossings of American and European cultivars and hybrids is studied. Five hybrid groups of various species have been analysed according to the trait 'bush height'. Combinations of crossings together with the genetic basis of the three species Gr. robusta, Gr. succirubra, Gr. reclinata and Gr. succirubra, Gr. hirtella, Gr. reclinata are characterized by the highest output of hybrids suitable for mechanical harvesting. The basic types of the inheritance of the trait 'bush height' are negative domination and depression of tall-growth trait what witnesses about recessivity of this trait.
