ESTIMATION OF COMMON BEAN COLLECTION MATERIAL FOR MAIN ECONOMIC CHARACTERISTICS

Abstract

The paper provides the data on the estimation of variety samples of common bean (Phaseolus vulgaris L.) different in ecologic geographic origin from the collection of All-Russian Research Institute of Crop Production after N. I. Vavilov and National Bank of Ukraine. The samples were estimated on the experimental field of Siberian Research Institute of Crop Production and Breeding under Preobye forest-steppe conditions. The set of collection variety samples of common bean was studied for the expression of the main elements of productivity, such as plant height, lower bean’s higher fixation on the stem, the number of internodes, developed beans, and beans per plant, bean length, beans weight per plant, a single bean weight, yielding capacity as well as flower and bean coloring, cross-section shape and bean surface character, presence of fibers in the raphe and parchment layer in the beans. The coefficient of variation was calculated for all the elements of productivity to identify the samples with low variability and high efficiency for selection. Excellent quality green beaned samples were revealed which can be included in breeding programs as genetic sources of the main economic characteristics to create high productive varieties suitable for cultivation under Siberian conditions.
