Badanie zmienności fenotypowej genotypów lnu oleistego (Linum usitatissimum L.) za pomocą statystycznych metod wielowymiarowych Investigation of phenotypic distance of genotypes of oilseed flax (Linum usitatissimum L.) using multivariate statistical methods

The aim of this study was the multivariate characteristics of the variability of ten traits of eighteen flax objects. The multivariate analysis of variance and canonical variate analysis were used. The plant material consisted of 12 breeding lines and 6 registered varieties of flax The experiments were carried out using completely randomized design in three replications during two crop seasons of 2008 and 2009 in an experimental station of Institute of Natural Fibres & Medicinal Plants in Wojciechow. Tested genotypes of flax were evaluated in respect to ten quantitative traits. Multivariate analysis of variance showed significant differences of the investigated genotypes and expression of genotypes in the years of study. The results of canonical variate analysis revealed differences between all the experimental objects in the years of study. Statistically significant correlation of Mahalanobis distance obtained in both years, r = 0.5942, P < 0.001, was found.. Genotypes having the greatest genetic diversity can be used to create a gene pool of flax.
