The research aimed to compare the phenological, morphological and biochemical characterestics of plain and curly-leafed parsley hybrids. The hybrids were similar in germination percentage and leave number as well as in the content of NO3. Significant differences were observed in leaf area of plain and curly-leafed hybrid (21.23 vs. 10.87 cm2), stem length (11.68 vs. 5.42 cm), fresh (56.8 vs. 31.95 g) and dry weight (4 and 1.92 g, respectively). Comparing to plain-leafed, the curly-leafed hybrid had a twice thicker stem, higher chlorophyll, carotene and vitamin C contents (37,45, and 14.61%, respectively).
