Babitch V. Economical value traits of sunflower parental lines hybrids of PBGI breeding and its control in the seed production.

The new and also improved parental lines and hybrids of sunflower of the first generation, culturing in seed-growing Ukraine under license contracts. Aim: optimization of ways of manufacture of seeds of hybrid sunflower which cause maintenances of a high level of his{its} hybridity and typicalness of lines. Novelty: Have developed and have introduced a technique of an assessment of a level of typicalness behind a parameter „ attachment a sterility of female forms of hybrids of sunflower ” and proved efficacy of use of a method electrophoresis the analysis helianthine in comparison with a method of the earth control over assessments. Results: It is introduced into a seed growing of Selection -genetic institute a new seed grain of selection SGI the substantiation of parameters compound in hybrid seeds of other forms of sunflower which authentically do not influence productivity and the tax of oil from unit of the area is lead{carried out}. Application stage: the technique of an assessment of female formsin greenhouses of a photothrone is offered. Application area: research institutions UAAN.
