Information × Registration Number 0216U000679, 0111U003473 , R & D reports Title To study correlation between duration of the dormant period of vegetation and productivity, as well as frost hardiness and using genotypes with a short dormant period to develop and transfer to the state variety trial alfalfa varieties for the conditions of the Steppe region of Ukraine with productivity of dry matter 7,0-7,5 t/ha, seed yield – 0,25-0,35 t/ha, resistant to the major diseases and tolerant to drought popup.stage_title Head Bushulyan Oleg Volodymyrovych, Registration Date 18-02-2016 Organization Plant breeding and genetics institute-National center of seed and cultivar investigation popup.description2 The object of research - grade individual phenotypes (clones), hybrids and self-pollinated lines of alfalfa.The purpose of research - improvement of existing and development of new methods for the creation of the original source material and the creation on its base of alfalfa varieties with reduced rest period and increased forage and seed production are resistant to the most harmful diseases with high drought tolerance and wintering. Research methods - field, vegetation and laboratory experiments and statistical analysis of the experimental data. Theoretical and practical results. Created and studied a large number of clones, hybrids and self-pollinated lines on the basis of a long dormant period (vegetation). Identified genotypes that combine a short period of rest with high productivity, a significant portion of the harvest that forage in the first and second mowing exceed the standard a 100%.Among the varieties most resistant to root rot appeared Zarnitsa, Mriya odesskaya, Eva, Luba, Rosinka, Laska, Nishnist’, Nasoloda and among the promising material 9 rooms. The whole experience there was a decline in the productivity of infectious background, which averaged 6.5%. The high level of stability of the alfalfa varieties, selection of GIS, and a sharp decline in productivity varieties Roxolana on infectious background, which amounted to 51.2%. The technology of growing alfalfa seed purposes in the arid conditions of the south of Ukraine. It was found that the dry conditions of the Odessa region, the most productive crops with wide aisles 45 and 60 cm with a seeding rate of 0.5-1.0 mln. germinating seeds per hectare.During the reporting period created and transferred to the state variety testing three varieties of alfalfa Nasoloda (2011), Golubka and Lada (2015). Varieties Nasoloda and Golubka characterized by a short period of rest and an extended growing season in the fall, Lada - also determined by exceptional drought.New varieties due to the short period of rest, lengthening growing season in the fall and a high drought tolerance will be high demand for agricultural producers in Ukraine and will occupy more than 25 000 Ha. Due to only an additional fee of dry matter per year, they will make a profit of 1.5-2.0 mln. UAH, and seed crops - 3.0-3.5 mln. UAH income.
