Objective: In the collection nurseries identify the main sources of economically useful traits (quantitative) marker signs. On the basis of the nature of inheritance of traits and setting the coefficients of correlation between them, to create a source material for breeding new varieties of flax highly Kudryash. For all types of nurseries (collection, breeding hybrids F1-F4, breeding nursery, pre-strain testing, competitive strain testing) identify breeding patterns that the yield seed oil content in seeds, collecting oil from 1ha exceeded the standard sort of southern night of 5-15% . Results and novelty. To create a new source matkrialu for further breeding varieties involved in hybridization Kudryash flax, flax and flax breeding samples mezheumka. In hybrid combinations of crosses first and second generations F1-F2 studied the basic nature of inheritance of economically useful traits - yield seed oil content in seeds, resistance to lodging and disease and marker characteristics - color petals and anthers of flowers and color shells seeds. According to studies in various categories nurseries color samples flax that for individual characteristics and for complex traits exceed standard grade South night. In particular, the Collector's nursery varieties and selected 24 samples that exceeded the yield seeds on standard 8-20 g / m2 with standard yield 144 g / m2. Also selected 18 samples in which the oil content in seeds was at 40,9-43,8% and 38.6% in the standard. In breeding nursery for seed yield varieties and selected 45 samples exceeded the yield on a standard 8-12 g / m2 at productivity standard 12,3-13,6 g / m2. With 42 rooms the previous breeding quality testing by the complex of economically useful traits selected 3 samples to ensure the collection of oil 639-717 kg / ha at 498 in the standard. For oil content in seeds and seed yield in competitive strain testing selected samples during breeding №№ 5,8,9 with seed yield vidpovidno1,73; 1.74; 1.76 t / ha, yield grading Southern Night 1.44 t / ha, one or two of which in 2014 will be transferred to the state testing. According to the research of the past years in the State Register of Plant Varieties of Ukraine for 2011 recorded new high-grade linseed bluish-orange, Eureka, Оriginal.
