Demydiuk M. Genetic conditionality of grain productivity and quality characteristics and their importance for pea breeding.

Object of study - especiation, formation and expression of agronomic traits pea. Purpose - determining the characteristics of variability, inheritance elements of performance indicators and quality of grain in view of their genetic characteristics, installation efficiency of selective use of modern varieties and the creation of the basis of lines of pea. Methods - field (visual, hibrydolohichnyy) and laboratory (weight, Biometric, mathematical and statistical). Implementation - collectible exsamples found with high levels of stability and plasticity signs of productivity and quality of grain; examples with high protein content in the seeds and high yield and genetic sources of high protein content; identified varieties and hybrid combinations of high impact general and specific matching capacity; leased lines with high yield and other complex agronomic traits; created and transferred to the state quality testing grade pea Jordan. Area of use - breeding research institutions.
