Gorlachova O. Development of the initial material for breeding millet for productivity and grain quality in the Eastern Forest-Steppe of Ukraine.

Subject: breeding of millet. Aim: to develop original material of millet to use it in the breeding programs for the Eastern Forest-Steppe of Ukraine. Methods: field, hybridization, laboratory, math-statistical. Novelty: In the conditions of the Eastern Forest-Steppe of Ukraine there is established the reaction norm in the variety-samples from the world collection of millet; there have been identified the forms possessing high general adaptivity to environmental limiting factors as for major economical traits; there has been found a correlation between grain carotenoids content and these indices; there have been revealed the donors with increased content of carotenoids and there has been determined the nature of inheritance of this trait; there have been established the principles on prognosis of transgressive selection for quantitative traits in millet. Results: there has been identified the adaptive original material with high genetic potential for economic traits and have been developed such millet forms 03-2290, 03-2404, 03-2348, 03-2150, 03-2367 and 03-2494 with the complex of economic traits. Application stage: there have been released some stable lines; they are included in the breeding programme of the laboratory for millet selection of the Plant Production Institute d.a. V.Ya. Yurjiev UAAS, they have been passed to the Institute of Farming, UAAS, and to the National Center for Plant Genetic Resources of Ukraine as the sources of major economic traits of millet. Application area: selection, plant breeding.
