A group of autotetraploids of black currant (Ribes nigrum), red currant (Ribes rubrum) and gooseberry (Grossularia reclinata) have been studied. The comparison of the characteristics of autotetraploid forms with diploid cultivars shown that the autotetraploids are characterized by a new set of morphological, anatomical and biological traits inherent to this level of ploidy. Despite the fact that the reaction of each trait to the doubling of the chromosomes number is determined by the specific genotype of each variety, there is a clear parallelism in the variability of the same traits in different species of the family Grossulariaceae Dumort. The obtained data indicate that the doubling of the chromosomes number of diploid varieties leads to increased resistance of the autotetraploid forms to pathogens and also to an increased amount of the vitamin C in the fruits. |
