Геометрическая характеристика зерна те-траплоидного вида Triticum carthlicum Nevski. В условиях Северной лесостепи Тюменской области

Results of studying 42 hybrids of tetroploid species Triticum carthlicum Nevski are presented. On indicators of physical and chemical properties of grain. Researches are spent for the purpose of definition of the perspective genotypes having a high indicator of a mass fraction andosperm in grain for practical selection. As standards used grades of soft wheat the Skala and Novosibirsk 15, and firm Bezenchuksky141. Measurements of the linear sizes of grains have shown wheat, that on length (6,24 mm), width (2,80) and a thickness (2,64 mm) grains this kind was at level soft, but has conceded to firm wheat. By means of electronic microscope Axiostar plus the thickness of pericarp and perisperm at grains kartalinsky wheat is defined. The thickness of fruit and seed covers in the top part of grain was more on 8,46 μm in comparison with two lateral points of gaugings and has on the average made 39,05 μm. On the basis of the received data at hybrids the volume of grain (V=24,2 мм3), a surface grains (F=59,8 мм2), volume of external covers (Vi=2,5 мм3) and weight of a germ (Мз=2,5 %) is defined. Mass fraction calculation amyloid of part endosperm has shown parts, that at kartalinsky wheat it has made 87,8 % at average productivity 237,5/m2 excess on this indicator over grades of soft wheat the Skala (82,1 %) and Novosibirsk 15 (81,2 %) Is noted. As a result of the spent researches from a collection are allocated hybrids T carthlicum with the high content amyloid parts of endosperm in grain. It К-11890 (88,7 %), К-18604 (88,9 %), К-7882 (87,7 %), К-13822 (87,9 %), К-17703 (88,0 %), К-32484 (87,3 %) and К-36221 (87,7 %).
