Chinese mustard is a perspective vegetable species due to its high nutritional value. The aim of this work was an evaluation of Chinese mustard assortment for hydroponic cultivation, comparison of morphological parameters and nutritional value of fresh leaves. The highest mean weight of one plant was shown in cv. Red Giant (179 g). The biggest leaves with the length of 459 mm were formed by cv. Ta Tou Tsai. The highest cultivar was Cai Cai Tai (1,063 mm), with an abundant number of leaves (57 leaves). Cv. Osaka Purple Leaf showed the highest content of vitamin C (738 mg/kg); the highest carotenoids content (899 mg/kg) was found in cv. Swollen Stem. The mean content of chlorophyll <i>a</i> was 2,804 mg/kg; for chlorophyll <i>b</i> it was 1,103 mg/kg. In addition, the results of the content of dry matter, K, Ca, Mg, Na and nitrates are presented in this work. The evaluations showed a significant effect of cultivar on morphological and most of nutritional parameters. Chinese mustard is also suitable for soilless cultivation.
