The manifestation of properties in distant hybrids of Ribes L. and Grossularia Mill. (Ribes uva-crispa L. subsp. reclinata (L.)) with different genomic composition

Abstract

The results of long-term experiments to study the development of traits and biological features at the distant hybrids currants and gooseberries with a different genomic composition. It was established that amfihaploidy differ from the original parental forms with character of growth and color shoots, close fitting bud palet, bud shape, the size of leaves, inflorescence, flowers in the flower racemes. It was determined the possibility of using allotriploidy forms as an intermediate in the preparation of allotetraploid and fertile diploid recombinants with economically valuable traits. It was identified that some forms of amphidiploids have the complex shapes immunity, increased winter hardiness, fruits with large and small seeds.
