Leguminous Plant Productivity under the Dry Conditions of Dagestan

A comparative analysis of the variability of traits of seed productivity of leguminous plants was carried out in the dry conditions of zones of Dagestan with common beans as a representative of the oldest culture with high productivity. The correlation of the weight and numerical characteristics of seed productivity, varietal diversity, and high-altitude gradient in their variability is estimated. The random character of the influence of varietal diversity on the variability of weight characteristics of seed productivity and the insignificant effect of the altitude gradient on the variability of the dry mass of fruits and seeds, for which the differences in the mean values of the Student’s t -test were noted, are determined.
