Study of genetic variability of representatives of Ribes L. grown in Belarus

Resumo

The study of genetic variability of Ribes L. representatives grown in Belarus using seven loci of microsatellite sequences showed that modern Belarusian varieties of black currant are characterized by high genetic variability and have a close genetic relationship with foreign selection varieties. The number of alleles in the studied loci varied from 5 to 11. The average number of unique genotypes among 65 samples was 43.1. The discrimination power of the markers varied from 0.67 to 0.95 and the mean value was 0.84. All markers have rather high diagnostic value and make it possible to identify black currant and gooseberry varieties at the molecular level and, therefore, can be recommended for DNA-identification of these cultures.
