AMPELOGRAPHIC EVALUATION OF THE MAIN PHENOLOGICAL, VEGETATIVE AND PRODUCTIVE CHARACTERS OF WHITE SHESH GRAPEVINE CULTIVAR, UNDER TIRANA CLIMATE CONDITIONS

White Shesh is a native (indigenous) cultivar selected and cultivated in centuries from winemakers of Tirana`s Shesh and Ndroq areas, in the middle of Albania, where it gets its name. Study was conducted during three consecutive years, 2019-2021, in a representative sample of 10 vines, in a nine years old vineyard, located in a flat land 76 m above the sea level, in Zallherr, Tirana. Observed results showed that under Tirana climate conditions, bud burst of White Shesh occurred in April 6, full bloom on May 28, berries veraison on August 2, grape maturity on September 27, and natural leaf fall occurred on December 15. Vegetative period extended 244 days and the period from blooming to harvest was 122 days. Three years mean of the sum of active temperatures (>10oC) was 2196oC and the sunlight radiance was 1267 hours. Insertion of the first inflorescence starts at 5-th node and each shoot generates 2 inflorescences. The flower type was hermaphrodite (fully developed of male and female organs). Bunches were medium dense, with a conical shape. Length was long 260 mm and weight was 410 g. Yield per vine was 3.1 kg or 117 quintals ha-1. Berries were round and uniform with a mean weight of 3.2 g. Must yield was medium (63 ml juice 100 g berries-1), total sugar content of must was medium (19%), and total must acid content (tartaric acid) was medium (6.4 g L-1).
