Early-maturing varieties of open-ground tomato of domestic breeding in the conditions of the Tersko-Sulak subprovincion of Dagestan

Relevance. Dagestan is a zone of prosperous agriculture, distinguished by the abundance heat, sun and irrigation in plain zone. Tomatoes occupy special place among vegetable crops world, including Republic Dagestan. Determinant varieties are now most common production tomatoes, especially open ground. The main areas specialized cultivation tomatoes ground concentrated Kizlyar Derbent districts In these areas, there high average daily temperatures for formation ripening tomato fruits excess, which favorably reflected overall productivity bushes. Whereas foothills Dagestan, insufficient heat resources do not allow growing with long season. foothill part republic large labor-resource potential, growing, as labor-intensive type agribusiness, acts sphere employment significant rural population. demand short season this great. Methods. research was carried out on basis Tersko Sulak subprovincion FGBNU FANC RD district. soil experimental site alluvial-meadow, medium-saline, medium loamy mechanical composition. Agrotechnics generally accepted culture. Results. method study new semi-stamp cultivars FNCO (VNIISSOK) selection: Fakel (counter), Blagodatny, Viking, Voskhod VNIISSOKa, Magnat, Severyanka, Sodruzhestvo, Perst, Patrice. According to maturation dates, samples were divided into three groups: very early – VNIISSOK (97-100 days); Patrice, Perst (102-105 middle-early (111-114 days). bush, we have identified 5 ordinary semi-lamb height no more than 78 cm. Two had 50-53 cm (Patrice, Perst) an fetal weight 72 60 g. Three 70, 71, (Voskhod Sodruzhestvo) 107, 110, 130 output gross output, best indicators following varieties: Blagodatny 86.3; VNIISSOKa 82.7; Sodruzhestvo 77.6 t/ha; Patrice 68.2 t/ha. grades yield marketable products: 92%; 91%; 90%. also relatively dry matter index 5.3-6.4%.
