Erkenci Armut Çeşit Adayı Bazı F1 Melezlerin Morfolojik ve Ticari Değerler Yönünden Değerlendirilmesi.

In this study, physico-chemical and sensory evaluations of F1 genotypes that were obtained by hybridizations from 'Akça' which is a approvingly consumed early harvest cultivar in our country were made. Furthermore, the susceptibility level of hybrids to fire blight, which is the most devastating disease of pome fruit species was detected. Among the pomological characteristics, fruit width, fruit length, shape index, fruit weight and fruit flesh hardness were varied between 35.84 - 59.19 mm, 42.59 - 71.80 mm, 0.90 - 1.85, 25.53 - 101.40 g, 3.38 - 6.87 kg.cm², respectively. Soluble solid content, pH, titreable acidity, Vitamin C and antioxidant activity values were determined in the range of %10,93 - 16,77, 3,15 - 4,52, % 0.16 - 0.64, 2.00 - 5,33 mg.L-1 ve %23.37 - 81,20. As a result of weighted rating method, formed by the parameters which bring the commercial value of the genotypes to the forefront, four genotypes have the potential to be registered as early pear cultivar.
