Commodity and consumer qualities and chemical composition of fruits of promising breeding forms of apple for the Crimea

Abstract

The value of the fruits of the apple tree culture for the human diet is shown. The necessity of selection to improve the chemical composition of its fruits is justified. In the Russian Federation and the Republic of the Crimea as an integral part of it, all-round improvement of the varietal composition of apple trees should be accompanied by extensive use of the best selected or created new cultivars of local selection, including the Nikitsky Botanical Gardens. The objective of the research is to identify sources of economically valuable traits that are of interest for practical application and further selection. The article presents the results of a long-term study of the commodity and consumer qualities of 15 promising breeding forms of apple trees. The highest yield of commercial fruits was observed in four genotypes: 1-32-87, 2-6-13-82, 2-38-78, 3-6. The maximum weight of the fruit (226-224 g) differs in three breeding forms-3-6, 2-38-78, 3-6-47-79, according to the sugar content (12.7-13.1%), two are distinguished - 2-6-13-80 and 12-3-78. In terms of vitamin C content, four breeding forms, including 1-32-87 and 3-6, surpassed the control cultivar. During the organoleptic evaluation, the highest score was obtained by the control and selection forms 1-32-87 and 10-72-78. The selected genotypes are of considerable interest for practical use and selection.
