8275是以甘麦8号为母本、福区17为父本杂交,经在定西县唐家堡半干旱生态区多年选育而成的抗旱、中熟、丰产、稳产、优质旱地春小麦新品系。该品系株高100~110cm,茎秆细,长芒、白颖,千粒重40~45g,容重764~773g/L,籽粒硬质,含粗蛋白13.47%、淀粉63.83%、赖氨酸0.44%。生育期100d左右。苗期抗旱指数368.04%,后期抗旱系数84.2%,抗旱性与定西24基本一致。在1993~1995年全省旱地区试中,30点次的平均产量1786.2kg/hm2,较定西24和陇春8139分别增产4.9%和11.7%,居9个参试品种第1位,其产量主效应最大,为0.1915,品种与地点互作的变异系数为0.0004,具有良好的丰产、稳产性。在甘肃中部干旱、半干旱生态区的定西、会宁等县大面积示范种植,一般产量1800~3450kg/hm2,比陇春8139等主栽品种增产10%~15%。该品系适宜在甘肃中部干旱、半干旱生态区的山川旱地、梯田种植 8275 is a new spring wheat line with drought-resistant, middle-maturity, high yield, stable yield and high quality, which is made from the cross of Ganmai 8 as the female parent and Fuqu 17 as the male parent through semi-arid ecological zone in Tangjiabao, Dingxi County . The strain has a plant height of 100-110 cm and a stem diameter of 40-40 g and a grain weight of 764-773 g / L. The grain is hard and contains 13.47% of crude protein, 63.83% of starch, Acid 0.44%. Fertility period of about 100d. Drought index 368.04% at seedling stage, late drought resistance coefficient 84.2%, drought resistance and Dingxi 24 basically the same. In the experiment of drought area in the province from 1993 to 1995, the average yield at 30 o’clock was 1786.2 kg / hm2, up 4.9% and 11.7% respectively compared with Dingxi 24 and Longchun 8139, 1, the main effect of the yield was 0.1915, the coefficient of variation of the interaction of variety and location was 0.0004, which had good yield and stable yield. Large-scale demonstration planting in Dingxi, Huining and other counties in arid and semi-arid eco-zones in central Gansu province resulted in a yield increase of 10% to 15% with a typical yield of 1800 ~ 3450kg / hm2 and other main varieties than Longchun 8139. The line is suitable for cultivation of terraces in arid and semi-arid eco-zones in the central part of Gansu
