The qualitative and quantitative aspects of adaptation of the species signs in the family Gentianaceae are examined. The qualitative appraisal realize by ranking of phenes (variations) of one sign: widely meeting phene is signed as expressed by Greek capital letter Α, the alternative least meeting phene is signed as zero by small letter α; accordingly, intermediate variations are signed by combinations of the letters Αand α. As parameter for quantitative appraisal of variation’s adaptation was received the quantity of variation’s meeting in the system Α+ Αα+ α. Th e quantity of meeting is definited as correlation of the species number of individuals marking that sign (all phenes of sign). The increasing of ecological amplitude depending on increase of the quantity of meeting is noted: phenotypes with least of quantity of meeting have narrow ecological amplitude and meet mainly at the meadow and forrest-grassland habitats with sufficient humidifying, while the phenotypes with greatest quantity of meeting have the wide ecological amplitude and meet both at humidifying, and at droughty and cold habitats.
