OVERCOMING IINCOMPATIBILITY IN REMOTE RECIPROCAL CROSSES OF BLACK CURRANTS AND GOOSEBERRIES
The article deals with the data on influence of biologically active substances on overcoming the incompatibility in remote hybridization of black currants and gooseberries. The effective way to overcome the barrier of incompatibility of original parental forms of remote hybridization in the family Grossulari-aceae Dumort is the application of aqueous solutions of gumi and аgrostimulin (0,001 %), gidrogumatе and emistim (0,1 %), humate and ivin (0,01 %) to wash pestle of the parent plant before pollination. The application of indoleacetic acid as a growth substance is ineffective because alongside with an increase in fruit setting the germination of hybrid seeds reduces significantly.
