Pomological and morphological traits of some strawberry cultivars under Bursa ecological conditions

In this study, some neutral day varieties (Albion, Fern, Monterey, Portola, San Andreas) and some short-day varieties (Aliso, Annapolis, Arnavutköy, Bursa Derekızık, Mindoir, Pineberry (Ananas), Senga Sengana, Tudla, Tufts, Yalova-416, 39) to determine the phenotypic characteristics and performances. The first flowering and harvest dates of the cultivars were recorded, and a total of 32 characteristics, including plant, stolon, leaf, flower and fruit characteristics, were examined according to UPOV criteria. The degrees of chlorosis due to fruit load, plant power and Fe deficiency in leaves were determined visually. At the same time, fruit size, fruit weight, flesh firmness, titratable acidity, soluble dry matter, Ph value and sensory taste and odor characteristics of the cultivars were determined. It was recorded that the first flowering date of the cultivars was between 8 March-16 April 2020, and the first harvest dates between 11 and 20 May 2020. On the basis of varieties, it has been determined that fruit weight varies between 4.80 g and 17.81 g, fruit height values between 23.98 and 48.75 mm, width values between 19.93 and 31.83 mm. It was determined that "Monterey", "Portola" varieties have the largest fruits, "Bursa Derekızık", "Arnavutköy", and "Pineberry (Ananas)" varieties have the smallest fruits. The water soluble dry matter (SÇKM) amount of the cultivars varied between 6.4% and 9.9%, titratable acidity value between 0.53% and 0.91%, fruit flesh hardness value varied between 0.18 and 0.69 kg / cm² High flesh firmness was detected in 'Monterey', 'San Andreas', 'Portola', 'Albion' varieties. It has been determined that the fruit load is very good in '39' genotype, but good in 'Albion', 'Aliso', 'Fern', 'Mindoir', 'Portola', and 'San Andreas' varieties. It has been observed that the plant power is good or very good in all varieties except the 'San Andreas' variety. Severe chlorosis was observed in 'Fern' 'Pineberry (Ananas)', 'Tudla', 'Tufts' variety, moderate severity in 'Albion' variety, mild severe chlorosis in 'Monterey', 'Portola' and 'San Andreas' varieties, chlorosis was not observed in other varieties. Considering the characteristics examined, it has been determined that 'Monterey', 'Portola', 'Albion', which are neutral day varieties in terms of yield and quality, and 'Annapolis', 'Mindoir', 'Senga Sengana', which are short day varieties, stand out.
