Представлены первые результаты выращивания десертных сортов винограда Виктория, Италия и Ред глоуб в теплице, накрытой полиэтиленовой пленкой, в условиях Южной Болгарии. Установлено, что фенофазы их развития начинаются раньше и протекают значительно более ускоренно по сравнению с их культивированием на открытом воздухе в полевых условиях. Ввиду вырастания достаточно длинных побегов виноградные кусты можно начать формировать ускоренно еще в первый вегетационный период. Виноград исследуемых сортов во второй и третий годы выращивания в теплице достигает потребительской зрелости приблизительно на месяц раньше по сравнению с виноградом, выращиваемым в полевых условиях, а урожай с одного куста возрастает с 25 кг на второй год до 710 кг на третий. Полученный виноград отличается очень хорошими, хозяйственно важными агробиологическими и технологическими показателями.The article summarizes first findings on cultivation of dessert grapevine cultivar Victoria, Italia and Red Gloube in the greenhouse covered with plastic wrap in the conditions of south Bulgaria. It has been established that phenophases of their development begin earlier, and proceed much more rapidly, as compared to cultivationin in the open air. Development of sufficiently long shoots allows shaping grapevine bushes at an early stage during the first vegetation period. In the second and third years of their cultivation in the greenhouse, the grapes of the studied cultivars reach consumer ripeness approximately one month earlier than the grapes grown in the field. The yield from one bush increases from 25 kg in the second year to 710 kg in the third. The grapes obtained demonstrated strong, economically significant agro-biological and technological characteristics.

An agrobiological and techno-logical study of the Pamid grape variety was carried out during the realization of different variants of loading with winter eyes during pruning. An agrobio-logical and technological study of the Pamid grape variety was carried out during the realiza-tion of different loading variants with winter eyes during pruning. It has been established that the phenophases of development during the vegetation period occur and take place al-most simultaneously in the same time periods, and the grapes ripen during the first ten days of September. With the increase in the number of knots of a vine and with their lengthening, there is a well-defined tendency of reducing the percentage of developed winter eyes, fruit-ing shoots, weight per 1 cluster, less of reduc-ing the fertility rate. The vines grow well under the pruning loads of the four variants and the grapes manage to ripen. The best combination of sugar and titratable acid content for wine production is in the grapes from the variants with a load of 6 and 7 knots of a vine. The number of knots has a proven strong or moder-ate negative effect on the percentage of devel-oped eyes, fruiting shoots, bunches, fertility rate, weight of one cluster and 100 grains, dur-ing both years of the study. The increase in the number of knots is in a moderate, positive cor-relation with the yield of one vine.
