| Abstract: | The characters of desirable varieties of flax were analysed by using principal component analysis.The results showed that the characteristic roots of plant height (PH),effective bifurcations (EB) effective fruitages (EF) and thousand kennel weight (TKW) were accumulated at more than 90%.PH served as the first principal component,EB and EF the second and TKW the third. |
