Hyssopus officinalis L., f. cyaneus, f. ruber, and f. albus genotypes have been evaluated. In the drought conditions, the indices of the quantitative traits which directly influence productivity have a higher value for the f. ruber and f. cyaneus genotypes. The content of essential oil is different for the above mentioned genotypes, and much higher in f. ruber - 2.531, f. cyaneus - 1.877, and f. albus - 1.434% (s.u.). GC-MS essential oil analysis identified 30-38 compounds for different genotypes. The major compounds are pinocamphone in trans(-) iso and cis forms: for f. cyaneus, cis (-)pinocamfona - 51.77%, trans(-) iso pinocamphone - 6.70%; for f. ruber - 66.94% pinocamphone, 33.31% trans(-)iso pinocamphone, and 33.63% cis(-) pinocamphone; f. albus - 61.1% trans(-)iso- and 2.15% cis(-) pinocamphone, for all the genotypes followed by â-pinen (f. cyaneus, 8.49%, f. albus, 7.38%, f. ruber, 4.15%) and â-felandren, from 3.64% for the f. ruber genotype to 6.79% for the f. albus genotype. The minor compounds of essential oil have different concentrations, some of them being present only in one or two genotypes.
