To develop a method of complex assessment of soybean breeding material for stability and plasticity on economic and valuable grounds, methodical recommendations are issued. popup.description2 Object of research: selection and seed production of early and mid-ripening soybean varieties. The purpose of the work: improvement of the method of evaluation of the breeding material of soybeans for stability and plasticity according to the manifestation of macro-characteristics and the creation of high-yielding early-maturing and medium-maturing varieties resistant to abiotic factors. Research methods: hybridization, plant selection, field and laboratory, production testing, statistical analysis. The main results of the research: In the selection nurseries of all levels, the initial selection material that corresponds to the parameters of the task has been created. N 672-2, which provided a yield of 3.24 t/ha with a vegetation period of 94 days, and N 325-22 with indicators of 3.01 t/ha and 95 days, respectively, were selected in the group of ultra-early selection numbers. In the group of medium-ripe selection numbers, there are three numbers 429-21, 756-18 and 609-18. Among the selection material, both stable and plastic selection numbers are selected. The Siverka variety is relatively stable b=0.636, the Muza and Suzirya varieties are stable in terms of seed yield, their regression coefficient is close to 1, and the most highly productive breeding numbers that provided the highest yield this year are plastic. These are such as N 672-2 (b=2.59), from the ultra-early group, 122-14 (b=2.350), 429-21 (b=1.514). Parent forms, 4708/16, Commander, 4593-16, 4692-16 have been found to be resistant to cracking. Arnica/Comandor and 323-23/4593-21 ​​hybrid plants that did not crack at all were selected. Product Description popup.authors Tymoshenko Oleksandr O.
