Principal component analysis, based on 6 agronomic and fiber traits was used to evaluate the genotype diversity among 14 lines and 3 cultivars of cotton, tested across 3 years. Among the studied genotypes the lines Nos. 409, 412, because of their longer fibers and bigger bolls, and No. 400, distinguished by a remarkable earliness, higher productivity and higher lint percentage were the most interesting for the cotton breeding. This analysis can provide additional useful information about the trait links and their changeability in different environments.
