Abstract

One of the reasons hindering the wide use of distant hybridization in the selection of currants and gooseberries is non-crossing of the original parental forms. Non-interbreeding can manifest itself from the moment pollen enters the stigma of the pistil, when the growth of pollen tubes is delayed and suppressed, or when certain stages of the development of the embryo and endosperm are disrupted, which causes death or the formation of a defective hybrid seed. The article presents data on the influence of biologically active substances on overcoming incompatibility during remote hybridization of the black currant and the gooseberry. An efficient method of overcoming the barrier of incompatibility of the initial parental forms during remote crossings in the family Grossulariaceae Dumort. is application of water solutions of gumi and agrostimulin (0.001 %), gidrogumat and emistim С (0.1 %), gumat and ivin (0.01%) for
washing of the parental plant pistil before pollination.
