The article presents the material on the study of biochemical parameters of carrots of domestic and foreign selection. Carrots were grown in the ground in the peasant farm of A. P. Korneev (Kanikurgan, Blagoveshchensk district, Amur region). According to the sugar content, Primorskaya 22 and Shantane Korolevskaya varieties were in the lead. The total acidity in terms of malic acid varied from 0.053 % (Baltimor F1 hybrid) to 0.199 % (Shantane Korolevskaya variety). The content of ascorbic acid in carrot roots varied from 4.39 mg/100 g (Typhoon variety) to 8.80 mg/100 g (Shantane Korolevskaya variety). The ash content of table carrot root crops averaged 0.55±0.18 %, the dry matter content was 13.11±1.37 %. The highest level of accumulation of carotenoids in root crops was noted for carrot varieties Typhoon and Surazhevskaya 1. Carrot varieties obtained by breeders of the Primorsky Vegetable Experimental Station (branch of the Federal Research Center for Vegetable Growing), are characterized by signs that allow getting a stable harvest, have better biochemical indicators in comparison with foreign hybrids. This determines their competitiveness; therefore, plant growers of the Amur region successfully use carrot seeds of domestic originators.
