abstract:
Genetic diversity of 13 polish oat varieties was evaluated using cytogenetic and molecular analysis as well as measurement of some yield traits. No significant differences were observed in regard to pollen viability which oscillated from 99.3% for cv. Komes to 96.4% for German. However, significant differences referred to pollen grain size. The German variety had elliptic grain, when pollen grains of the Góral and Komes varieties were almost round. Analysed oat varieties differed also significantly in regard to some quantitative traits. Differences affected height of plants, size and shape of panicle, mean spikelet fertility, and 1000 kernels weight. Genetic similarity of varieties was estimated on the basis of PstIAFLP markers and analysis of pedigree. The first method points to higher genetic similarity. The results give information indicating that, in spite of many differences, the tested varieties are genetically very similar.
