Regularities of formation of quantitative morphometry of fаba bean plants in the system of variation-correlation analysis.

Purpose. The in-depth study of the source material for modern directions faba bean breeding further use in creation high-yielding varieties Forest-Steppe Ukraine. Methods. Field, morphometric, statistical, analyzes on basis generally accepted and special methods plant breeding, seed crop production. Results. results modification variability absolute relative quantitative traits plants are presented, interrelation is investigated contribution individual elements productivity structure to total yield determined. Environmentally stable indicators simple indices have been identified, that can be used genotype identification selection established. Given high identification, it advisable height number nodes per plant, where coefficients variation were less than 10 percent. For beans, most environmentally harvesting index, seeds bean, internode length, microdistribution index. According correlation analysis, was found closely correlated with following indicators: aboveground mass, beans weight pod flaps plant. Conclusions. These studies allowed identify ecologically indicators, indices, ecological which original traits, analysis relationships within species a should fodder breeding.
