Agronomic characters and commodity and consumer qualities of new varieties and hybrid forms of cherries in the conditions of Dagestan

Studied were the yield, biochemical composition, tasting and consumer quality indicators of 24 hybrid forms and 12 varieties of cherry bred by the Dagestan Breeding Experimental Station of Fruit Crops. The research was carried out using conventional methods of analysis and standard methods of cherry variety studying. Of the group of varieties of early-medium ripening, the best distinguished by a high content of soluble dry substances, sugars and vitamin C were the varieties Zhemchuzhnaya, Granatovaya, Almaznaya, Bigarro Krainskogo, Bereket, and hybrid forms 31/7; 109/1 and 180/1 in which the mass concentration of these substances ranged from 12.4-14.7 %; 10.34-12.85 % and 6.9-9.5 mg%, respectively. Among the varieties of medium ripening, the largest ability to accumulate soluble dry substances, sugars and vitamin C in fruits was shown by the varieties Bujnakskaya chernaya, Lezginka, Maral and hybrids numbered 43/2; 190/4 and 71/3 in which the content of these components of the chemical composition was 12.4-16.6 %; 10.53-12.19 % and 7.2-9.2 mg%, respectively. The best indicators of fetal weight, compared to the control variety of cherries Dagestanka (7.4 g) in the group of varieties of early-medium maturation were shown by: Zhemchuzhnaya (8.0 g); Granatovaya (8.2 g) and Bereket (8.3 g). Among the varieties of medium ripening, a more significant mass of the fruit compared to the control variety Napoleon chernaya (7.2 g) was in the varieties Maral (7.4 g) and Bujnakskaya chernaya (8.3 g). The highest overall tasting rating (4.9-5 points) was received by the fruits of the varieties Granatovaya, Bereket, Zhemchuzhnaya, Lezginka, Bujnakskaya chernaya and Maral. The same varieties had good indicators of average yield (t/ha): Granatovaya – 9.78; Bereket – 8.72; Bujnakskaya chernaya – 7.59 and Maral – 7.54. Taking into account the results of the studies carried out, it can be concluded that the varieties of cherry bred by the Dagestan Breeding Experimental Station of Fruit Crops Granatovaya, Bereket, Buinakskaya chernaya and Maral the fruits of which have the best agronomic characters and high commodity and consumer qualities, can be submitted for state variety testing and used in breeding work.
