摘要:

为了培育高产稳产、抗旱节水、多抗广适的突破性小麦品种,以高产品种‘临麦2号’为母本,以高产抗旱品种‘烟农19’为父本,采用系谱法聚合二者优异农艺性状,通过多点多生态鉴定与评价,育成小麦新品种‘济麦262’。该品种产量高,品质优良,抗病抗逆性好,农艺性状优异,水旱兼用。在2010—2011年度济南和蒙阴水浇地品比试验中,平均产量较对照‘济麦22’增产2.87%和9.41%,均居第一位;在2012—2013年度山东省旱地区域试验中,平均产量较对照‘鲁麦21’增产9.74%,是近10年来增产幅度最大的旱地小麦。该品种籽大饱满,籽粒蛋白质含量、湿面筋含量和面粉白度等品质指标优于对照品种‘鲁麦21’;抗干热风,中抗条锈病;株高67.2 cm,后期叶片功能期长,落黄佳,长方形穗,穗粒数37.5粒,千粒重44.7 g,白粒,粉质。‘济麦262’于2016年2通过山东省审定,适宜在无浇灌条件的旱肥地及水资源匮乏地区种植应用。

Abstract:

To cultivate a breakthrough wheat variety with high and stable yield, drought tolerance, water saving and multi-resistance, taking high-yield variety ‘Linmai 2’ as female parent and high-yield, drought-tolerance ‘Yannong 19’ as male parent, we used pedigree method to polymerize both parents’ excellent agronomic characters, and bred a new wheat variety ‘Jimai 262’ by multi-site and multi-ecological field experiments. This variety was characterized as high yield, good quality, good resistance to disease and tolerance to stress, excellent agronomic characters and could be cultivated in both irrigated land and dry land. In irrigated field variety comparison trial 2010-2011 in Jinan and Mengyin, the average yield of ‘Jimai262’ was 2.87% and 9.41% higher than that of control variety ‘Jimai 22’, and ranked first in both sites. In the dry land regional trail 2012-2013 of Shandong Province, the average yield of ‘Jimai262’ was 9.74% higher than that of control variety ‘Lumai21’, achieved the highest yield increase of dry land variety in the past decade. The grain of ‘Jimai 262’ was big and full, the quality traits such as grain protein content, wet gluten content and flour whiteness were better than that of control variety ‘Lumai21’. ‘Jmai262’ was resistant to hot dry wind, moderate resistant to stripe rust, and the plant height was 67.2 cm. At the later stage, the leaf photosynthetic function period was long, the population was yellowing well, the spike was oblong, the grain number per spike was 37.5, the thousand-grain weight was 44.7 g, and the grain was white and silt. ‘Jimai 262’ was released by Shandong Province in February 2016, it is suitable for planting in arid fertile land and water deficient area without irrigation condition.
