Study of genetic diversity of collection material of peas (PISUM SATIVUM L.) in the Rostov region
The complex study of 257 collection samples of peas (PISUM SATIVUM L.) with various ecologic-geographic origins selected the sources with valuable economic and morpho-biologic traits and properties for using them in breeding of highly productive cultivars with good qualitative seeds adapted to the unfavorable environment. The study has been carried out under the conditions of unstable humidity of the southern part of the Rostov region. The studied samples have been differentiated into the morpho types of the plants according to their productivity and its elements. We have fulfilled the analysis of the plants according to their quantitative traits: plant height, a number of nods, a number of beans per plant, a number of seeds per bean, a number of seeds per plant. The sizes of a seed and plant productivity have been estimated. The productivity of seeds from collection samples of peas of various morpho types has been analyzed. The correlation analysis has been conducted; the correlation of studied traits with seed productivity which could be promising in the breeding process has been estimated. The sources with constant high content of protein in seeds have been selected; the correlation between protein content and seed productivity has been determined
