Information × Registration Number 0211U000880, 0106U009948 , R & D reports Title To select and submit for the state trial a variety of soybean with the yield of 28-30 centners per hectare and protein content 41-42, fat - 18-20% popup.stage_title Head Ivanyk Sergiy Vasilyovich, Registration Date 01-03-2011 Organization FEED RESEARCH INSTITUTE popup.description2 Object of research is a mechanism of productivity formation of soybean variety numbers depending on the abiotic factors in conditions of the right-bank Forest-Steppe of Ukraine. Aim of research is to breed new soybean varieties on the basis of selec-tion from the new breeding materials by the parameters of the future variety using a field experiment, hybridological, morphometric, biochemical and statistical methods on the basis of generally accepted and special techniques of plant breeding. Nearly 19000 numbers are studied, soybean hybridization in 221 combinations is carried out and hybrids in 199 combinations are obtained. With the help of saturating crossings hybrids are obtained and combinations characterized by high economic characteristics are selected for further breeding. In all breeding nurseries perspective soybean breeding numbers that correspond parameters of the future variety, the seed yield of which has been 25,3-32,3 centners per ha that is 2,6-7,5 centners per ha more that in the standard and the duration of vege-tative period of 105-117 days that is 1-9 days less than in the standard are selected. Soybean variety Knyazhna (application for plant variety № 08018008) is on state trial since 2009. Scientific theoretical elaborations are used by the Ukrainian scientists-agrarians and practical results are introduced in agro-formations of different ownership forms.
