During 2011-2013 in comparative variety trial 11 new and two standard cotton varieties were tested. The varieties were obtained from two different targeted programs – for yield and for fiber quality with the application of different breeding methods. The results of the two-factor analysis (varieties-years) showed that the differences between the studied characters, except first picking, were significant, which means the varieties differed in them. Year conditions had the highest participation in the general variation of all characters (52.58 to 67.08%). The varieties Pearla-267 and Vicky had the highest seed cotton yield, exceeding the standard variety Chirpan-539 by 10.2 to 10.6%, average of three years. Best combination of length and lint percentage of the fiber was found for the varieties Darmi, Vega and Boyana. The studies are still focused on: creation of source material with diverse germplasm; maintenance and use of the genetic resources; heterosis based on male sterility; application of biotechnologies; drought resistance with reference to the selection of tolerant genotypes; resistance to Verticierum dahlia Kleb and seed production of regional varieties
