    CHARACTERIZATION OF GENETIC DIVERSITY AND STRUCTURE ANALYSIS WITHIN PEA (Pisum sativum L.) GERMPLASM AT AGRITEC LTD. COLLECTION.

  • Original language description

    The 164 accessions representing Czech and Slovak varieties bred over last 50 years were selected for evaluation of genetic diversity in this study. These were characterized by 42 morphological descriptors in two growth seasons, and DNA of bulk made from10 plants per accession was investigated by several molecular markers, including microsatellite SSR and retrotransposon-based markers. In total, 12 selected SSRs, 25 RBIP markers and 2 IRAP markers produced altogether 56 scorable polymorphic data pointsfor each accession. To enable integration and evaluation of all data in one analysis, Bayesian method using BAPS software was applied. The most informative and the best corresponding to pedigree showed the consecutive calculation first by morphological follow by molecular data. Division into 3 distinct breeding periods has revealed significant decrease in genetic diversity over time.

    Charakterizace genetické struktury kolekce hrachu (Agritec Ltd.)

  • Czech description

    Byla studována genetciká diverzita 164 položek hrachu českého a slovenského původu pomocí 12 SSR, 25 RBIP a 2 IRAP molekulárních markerů, společně s 42 morfologickými deskriptory. Získaná data byla analyzována pomocí výpočtu genetických vzdáleností a následné shlukové analýzy. Morfologická data takto rozdělily studovaný soubor na 5 až 7 shluků, zatímco molekulární pak na 6 až 7. Pro možnost integrace abou systémů byla využita Bayesiánská analýza pomocí BAPS software, jež vyústila v postupné odlišení shluků. Rozdělení souboru dle šlechtiteslkých period pak naznačilo existenci zůžení genetického spektra.
