Abstract

In the work, the biological and agronomic evaluation studies of tomato varieties Lia, Titan, Orange, Eraz, Marine and Cherry Zeytun were carried out. The results of the study of biological and agronomic characteristics of tomato varieties showed that from seed germination to seedling took 5-7 days, from flowers - 65-74 days, seed germination from first harvest or biological maturity - 102-114. days. According to the research results, tomato yield: Lia (St) 701.25c/ha, Titan: 965.5 c/ha, Orange: 900.3 c/ha, Eraz (St): 853c/ha, Marine: 1055.55 c/ha. , Zeytun was 32.5 c/ha. Titan, Orange, Marine varieties stood out for their high yield, which surpassed the testers. The content of dry matter in tomato varieties Lia (St) was 7.3%, Titan: 7.5%, Orange: 7.2%, Eraz (St): 7.3%, Marine: 7.4%, Zeytun: 7.6%. Lia (St) sugar content was 4.8%, Titan: 4.9%, Orange: 4.1%, Eraz (St): 4.5%, Marine: 4.7%, Zeytun: 5.1% , vitamin C content: 35.65, 37.65, 35.75, 33.55, 33.65, 38.55 mg%, acidity - 0.45, 0.46, 0.51, 0.47, 0.48, 0.48%, respectively. Titan, Marine, Zeytun. The results of the cultivation of new varieties of tomatoes Titan, Orange, Marine, Zeytun, according to biological and agronomic assessment, are adaptive in the hot climate conditions of Armenia.
