The biodiversity of production traits as the basis for selection of Chaenomeles Lindl. in Tambov region

Abstract

The purpose of this study was to analyze the biodiversity of morphological and biochemical traits that are important for the breeding process. We used 14 varieties of Chaenomeles Lindl. (Rosaceae) tested at the biological station of the Michurinsk State Agrarian University in the Tambov Region. The data on the decorative qualities of flowers are presented. The presence of various colors of the corolla, simple and semi-double flowers are shown. The analysis of the ranges of variability of such traits as the length and weight of fruits, the content of dry matter, sugars, titratable acids, ascorbic acid and catechins was carried out. The conclusion is made about the presence of biodiversity in the Chaenomeles gene pool, which makes it possible to continue the selection of universal varieties used for decorative purposes and as a high-vitamin fruit crop.
