中文摘要	国际玉米小麦改良中心(CIMMYT)的小麦种质具有优质、多抗、适应性广等特点。为了解CIMMYT不同选种圃材料在甘肃春麦区的表现,2013-2014年对来自CIMMYT的1 023份不同小麦选种圃种质进行了两点次(兰州和武威黄羊)农艺性状综合评价。结果表明,高降雨量圃材料籽粒小,红粒,植株较对照宁春4号高10 cm左右,生育期100 d以上,易倒伏,千粒重低,穗粒数少,丰产性差,不适宜在试验区直接种植,可用作品种改良的中间材料;半干旱圃材料白粒,抗条锈,平均株高70 cm,生育期90 d左右,适宜于生育期内灌一次水或播种前仅灌冬水的生态区域种植;灌溉圃面包材料变异类型多,白粒,长芒,抗条锈性好,总体上植株偏高(两试点较宁春4号高5~10 cm),产量较宁春4号偏低或持平。结合各类种质的农艺性状及丰产性,初步筛选出92份表现较好的材料。
英文摘要	Spring wheat germplasm from International Maize and Wheat Improvement Center (CIMMYT) possess good quality,multiresistance and wide adaptability. In order to verify the performance of wheat germplasm from CIMMYT selective nursery in spring wheat regions of Gansu,agronomic traits of 1 023 materials from CIMMYT were identified and evaluated at Lanzhou and Wuwei Huangyang in 2013-2014. The results showed that the wheat germplasm from high rainfall nursery,with small and red kernel,higher plant height,long growth period,lower 1 000-grain-weight,less kernels per spike,and lower grain yield,were not suitable to be planted directly in the tested ecological areas,but they can be used as breeding materials for quality improvement. Arid and semi-arid nursery materials from CIMMYT showed white kernel,resistance to stripe rust,70 cm in plant height and about 90 days of growth period,part of which were suitable to be planted in the area with single irrigation or irrigation before sowing. Bread wheat materials from irrigation nursery had many variations,with white kernel,long awn,higher resistance to stripe rust,5-10 cm higher in plant height,and lower or equivalent grain yield,compared with CK Ningchun 4. Totally 92 materials from CIMMYT with good agronomy characters and yield were selected.
