Assessment of commodity and consumer qualities of fruits of promising apricot forms

Abstract

The purpose of researches was the assessment of commodity and consumer qualities for fruit of promising apricot forms which have been bred in the Michurin Federal Scientific Center. 8 apricot genotypes breeding in this institution were studied. The regionalized variety U’lyanikhinsky with its high level of commercial consumer qualities of fruit was used as a control. Fruit skin strength was assessed at the stage of consumer maturity using an FT30 penetrometer with a plunger diameter of 8 mm. Weighing was carried out on an AND EJ-6100 laboratory balance. The content of soluble solids was determined with an MT-032ATS field refractometer. Statistical data processing was carried out using computer programs Microsoft Excel 2007, Statistics. The largest fruit size was marked in Cezar variety. Average and maximum weights were 42.3 and 59.1 g, respectively. The least stone-to-fruit weight ratio (6.6 %) was found in Viking variety. The sample varieties Cezar, elite forms №1 and 3-5-7 are considered to be as freestone apricots. Elite form No. was characterized by an excellent taste of fruit. The fruits of the control variety «U’lyanikhinsky» and elite forms №1, 1-1-24 were distinguished by a strong juiciness of the pulp. The extremely rich fruit texture was observed in control variety U’lyanikhinsky and in Cezar variety, elite form № 3-5-7. The fruit of varieties Cezar, Viking and elite form No. 1 had the firmest fruit peel. The aforementioned apricots combined the attractiveness of fruits, their one — dimensional ground color with bright over color. Under the circumstances of the Central chernozem region the varieties Cezar, U’lyanikhinsky, Viking and elite form No. 1 pay attention to their high commodity and consumer qualities of fruit.
