Aim. Main aim of this research was identification of genetic distances between different genotypes of napa cabbage (B. rapa ssp. pekinensis) and diversity identification in var. glabra and var. laxa forms. Methods. Molecular genetic analysis of napa cabbage genotypes was conducted out using method of β-tubulin intron length polymorphism (TBP). Results. Molecular profiles of different napa cabbage (B. rapa ssp. pekinensis) genotypes were identified. Number of amplified β-tubulin intron fragments was significantly varying – from 12 to 24 for each genotype. Basing on obtained results a dendrogram was built, which shows genetic distances among studied accessions. Conclusions. In present study 7 genotypes of B. rapa ssp. pekinensis were analyzed, received from IPK (Gatersleben) and Crop Research Institute (Prague) gene banks. Basing on obtained results it was established that systematic diversification of two forms var. glabra and var. laxa is not being confirmed by molecular genetic methods, such as TBP, and in this case, genetic difference between populations and cultivars was more significant.
