摘要
冬小麦新品种天选55号为天水市农业科学研究所小麦育种中心以9589-8-1-2-1为母本、95-111为父本进行有性杂交,采用系谱法经多年选育而成。在2011—2013年甘肃省冬小麦陇中片旱地组区域试验中,2 a折合产量4 316.55 kg/hm^2,较对照品种陇中1号增产5.41%。该品种株高93~102 cm、穗长8.8 cm、千粒重49 g、容重812 g/L。籽粒含粗蛋白147.2 g/kg、湿面筋264.6 g/kg,沉降值25.5 m L。经接种鉴定,苗期对混合菌表现中抗,成株期对水4、贵22-14、贵22-9、条中33号、条中32号和混合菌均免疫,主要适宜于天水、陇南、平凉地区及定西东南部海拔1 800 m以下地区旱地种植。
Tianxuan 55 is a newly bred winter wheat cultivar by parental combination of 9589-8-1-2-1/95-111. The average yield Tianxuan 55 is 4 316.55 kg/hm^2,which is 5.41% higher than that of the check in winter wheat regional test conducted in the Longzhong district in the period 2011 — 2013. In addition,the plant heigth is 93~102 cm,ear length is 8.8 cm,thousand grain weight is 49 g,bulk weight is 812 g/L,seed crude protein is 147.2 g/kg,wet gluten is 264.6 g/kg and settlement of value is 25.5 m L. By inoculating indentification,the result shows that Tianxuan 55 has moderate resistance to at the seeding stage and immune completely to Shui4,Gui 22-9,Gui 22-14,CY 33,CY 32 and mixture race at the adult stage. It is suitable to plant at an altitude of 1 800 meters of Tianshui,Longnan region,Pingliang,Dingxi southeast region.
