Preliminary Results Regarding the Fruit Quality and Yield of Some Blueberry Genotypes

Abstract

Vaccinium corymbosum is one of the berry species with economic and food interest to Romanian growers and consumers. The development of blueberrty crop is a result of breeding activity, which has generated many cultivars of quality fruit and high productivity. The characters that are of economic interest in the cultivation of blueberries depend on the area of cultivation where the new cultivars are obtained. The study was conducted in summer 2020 in an experimental plot established in 2015 with seven blueberry genotypes, at Research Institute for Fruit Growing, Pitesti, Romania in the Small Fruit Laboratory, having an experience in the field of more than 40 years. The objective at this study is to compare some of fruit characteristics from genotypes 'Azur', 'Delicia', 'Duke', 'Northblue', 'Simultan', '4/6' and '6/38': plant yield, average fruit weight, fruit length, fruit diameter, the soluble solids, fruit acidity or pH, fruit firmness. During this study 'Delicia' cv. proved to have the highest production per plant (4.20 kg plant), the highest values of fruit diameter (19.70 mm), and the highest value of fruit total titratable acidity (01.25 %).
