Purpose of work: continuation of the study of perspective lines in breeding nurseries. Methods of researches: hybridization, selection, field and laboratory researches, production test, statistical analysis. Basic results of researches: сonducted researches in the direction of improvement of principles of selection of pair for hybridization for the selection of ultra-early and early sorts of soyа. In breeding for increased productivity should make more use of the following varieties: Legenda, Vision, Сorado, Elena, Angelica, Maheva, № 894, Annushka, Ustya, № 441. With the use of these varieties and breeding numbers of the most highly productive forms. In 2013, in the State Register of Plant Varieties suitable for distribution in Ukraine made ultra ripening varieties of Siverka. In the competitive strain testing was the most precocious breeding room № 15-11, which was the length of the growing season 85 days, which provided seed yield of 2.5 t / ha. He will be transferred to the state quality testing called Arnica. A sort of soy is Arnica it is shown out the method of individual selection from hybrid populaces of L.242/L.427. It is belonged to the Manchurian subspecies, approbation group of glauca. The height of plants 75-80 see. The height of attachment of lower bobs 10-12 see. Mass of 1000 seeds is 155-160 g. In seed contained 40-42 % to protein and 20-21 % to fat. An ultra-early sort in the conditions of the Kiev area ripens for 83-85 days. Proof to the defeat the most widespread illnesses, and also to the low temperatures in the period of flowering and fruit formation. A sort is recommended for growing in the forest-steppe and polissya districts of Ukraine in the basic, crop and yellowed sowing. Due to precocity can be used as a predecessor for winter crops. In provided the harvest of seed of 2,3-2,5 t/g competitive state testing Institute at the norms of sowing at the broad lines and string methods of sowing 700-750 thousands of alike seeds on a hectare both at the optimum terms of sowing (beginning of May) and more late, subject to condition application of effective herbicides and observance of other recommended agro technical receptions. This strain testing the best in performance were: number 200-07, which for the duration of the growing season 95 days, the level of seed yield of 2.9 t / ha higher than standard Ug-30 0.7 t / ha. The previous most harvestful strain testing was number 1016, which for the duration of the growing season 93 days, the level of seed yield of 2.5 t / ha higher than the standard Ug-30 at 0.5 t / ha. In control and breeding nurseries selected breeding material parameters corresponding to the task. Product Description popup.authors Романюк Лідія Сергіївна popup.nrat_date 2020-04-02 Close
