Distant Hybridization and Polyploidy in the Currant and Gooseberry Selection

Ամփոփում

The aim of the current research is to obtain domestic intergeneric hybrids, to assess their morphological, anatomical, biological and economic characteristics and to identify their perspective forms for further use based on the Belarusian varieties of black currant and gooseberry.
Intergeneric reciprocal crossbreeding of black currant with gooseberry was aimed at the production of thornless and semi-thornless gooseberry with a high content of vitamins and large-fruited currant resistant to gall mite. To overcome the sterility of amphihaploids, they were transferred to tetraploid level by colchicination.
Hybrids of R. nigrum x Gr. reclinata with different genomic composition have been bred.
