In 1996-2000 during expeditions were found and described 123 Carum carvi habitats. Mostly common caraway is found in pasture type habitats of Cynosurion cristati confederation communities. Plants of Carum carvi cenopopulations are characterized by wide diversity of phenotypic traits strongly influenced by ecological conditions and anthropogenic activity in natural habitats. The most stable parameters are weight of 1000 fruit and biochemical composition of essential oil. Essential oil synthesis in fruits is positively affected by warm and dry weather at the stage of caraway flowering – fruit ripening, carvone content – by warm and wet weather. The identified morphological types of Carum carvi leaves were as follows: normal, dill and parsley. Early-season caraway forms in comparison to others distinguished for the lowest height, fruit weight and total yield, but had the highest carvone content in fruit essential oil. Pink petals are characteristic for early-season caraway cenopopulations. White petal color, greater pigments amount in leaves, higher fruit productivity, as well as essential oil and carvone output characterize medium late and late forms. Various caraway genotypes with different levels of leaf carotinoids, chlorophyll content and ratio, anthocianins amount in petals, different reaction to cold and lighting stress reveal specific adaptive plasticity of caraway. Caraway intercenopopulation genetic diversity was determined at the molecular level.
