Morphological Description and Evaluation of Six Newly- Introduced Grape Cultivars under Egyptian Conditions.

Abstract

Six newly-introduced grape cultivars nemely Arra 30, Arra 29, Arra 13, Arra 24, Arra 27, and Arra 15, were investigated in three successive seasons ( 2014, 2015 & 2016) for description and evaluation under Egyptian conditions.The cultivars were grown in a private vineyard situated at Birqash region -Giza governorate, Egypt. Vines were planted in sandy soil spaced 3X2 meters apart and irrigated by drip irrigation system and supported by Gable system. The study included time of bud burst, young shoots, young leaves, shoot, and time of bloom, flower, mature leaf, beside determining time of ripening, Bunch, berry, Tss, Acidity, Tss / acid ratio, and seed formation.The studied cultivars were characterized by good vegetative growth and good fruit quality.

“…With respect to berry colour, it is clear that Early Sweet and Prime grape cultivars were yellowish green, while Star light grape cultivar was bright red. The findings obtained are in accordance with those of many investigators working on different cultivars (Ismail, 1989, Tourky et al, 1995Fawzy, 1998;Marwad 2002 a and b;Tarbia, 2017 andEl-Morsy et al, 2017).…”

“…The findings obtained are in accordance with those of many investigators working on different cultivars (El-Sharkawy 1995;Fawzy 1998;Marwad, 2002 a and b;Gaser, 2006;Girgis, 2007;Sabry et al, 2009;Tarbia, 2017 andEl-Morsy et al, 2017).…”

“…Previous studies were focused on describing and evaluating grape cultivars (Brooks and Olmo 1972;Watt, 1983;Walker and Boursiquote, 1992;Abd El-Kawi and El-Yam, 1992 a, b and c;Abd El-Fattah and Kastor, 1993 a and b;Morrison, 1994;Tourky et al, 1995;El-Sharkawy 1995;Fawzy 1998;Marwad, 2002 a and b;Gaser, 2006;Girgis 2007;Sabry et al, 2009;Abd El-Rahman, 2016;Tarbia, 2017 andEl-Morsy et al, 2017). Recently, some studies have used SCoT and ISSR markers successfully together successfully in the molecular diversity assessment of grape varieties, such as Abdel-Hameed et al (2020) and Bashandy et al (2020).…”

Evaluation of Yield, Fruit Quality and Molecular Diversity for Three Grape Cultivars under New Valley Conditions

“…In the past decade, it was almost cultivated with Thompson seedless and Romi Ahmar cultivars. Recently, many cultivars have been introduced to Egypt (El-Morsy et al, 2017).…”

Water strategy improves the inflorescence primordia formation of 'Arra 15' grapevine in the Brazilian semiarid region

“…Higher fertility in the middle branches when compared to the basal and apical region, regardless of the applied irrigation rate, may be related to genetic traits of the cultivar itself. In 'Arra 15' vines grown in a desert climate, there was also an increase in bud fertility from the basal buds to the middle buds and a gradual decrease towards the distal buds 12 .…”
