Abstract only

Maize material developed at the world breeding centers, which is available through the nurseries of Vavilov RI of Plant Industry (Saint- Petersburg), Mtskheta Breeding Station of the Georgian RI of Agriculture and Breeding and Genetics Department of Georgian Agrarian University is widely used in maize breeding. Especially valuable for breeding and genetics purposes are aboriginal populations of Georgian maize, being the genetic source of numerous beneficial traits and properties, namely: high adaptability to local soil and climate conditions, ability to form several ears per plant, drought and cold tolerance, earliness, hardiness, disease and pest resistance. Georgian nursery preserves various and numerous self-pollinated lines of national and foreign origin that are successfully applied as parent forms in development of heterotic hybrids. To enrich the nursery of Georgian self- pollinated lines different types of hybrids (inter- species, linear-species, simple interlinear, triple line, dual interlinear, multi-linear, as well as synthetic- hybrid population) and open-pollinated varieties have been successfully used. Selectively produced synthetics of recurrent (periodic) cycle have been recently used as the initial material in development of self-pollinated lines. Argentinean race Amargo and Mexican race Rapalote-chico are very interesting for enhancement of the genetic potentiality of Georgian maize. They are characterized by disease and pest resistance, formation of long (up to 30 cm) ears and long (up to 1,8 cm) grains. Peruvian races Curco and Curco Gigant (1000 grain weight almost 1 kg) are also remarkable for the big-sized grains. Bolivian and Columbian races are characterized by numerous aleuronic layers, determining high protein content of grains. Early, cold and drought tolerant races of maize were produced. Consequently, greater attention is to be paid to aboriginal forms and races of Georgian maize. Germplasm of Georgian maize creates an excellent opportunities for enrichment of local race breeding nurseries in the countries of American continent.
