摘要
天选67号是天水市农业科学研究所以CP20-38-4-3-2为母本,天选54号作父本进行有性杂交,采用系谱法经连续12 a定向选择而成。在2016—2018年甘肃省陇南片川区组冬小麦区域试验中,2 a平均折合产量7095.00 kg/hm^2,较对照品种兰天33号增产7.1%。该品种株高84.2 cm,平均穗长9.3 cm,千粒重44.26 g,容重819 g/L。籽粒蛋白质含量123 g/kg(干基),湿面筋含量254 g/kg(14%水分基),沉淀值49 mL(14%水分基),赖氨酸3.7 g/kg(干基),总灰分18 g/kg(干基)。经接种鉴定,该品种苗期对混合菌表现免疫,成株期对中4-1、贵22-14、条中34号、条中33号、条中32号、贵农其他及混合菌均表现免疫。适宜在天水市和陇南市川区种植。
Tianxuan 67 is a winter wheat cultivar,bred the parental combination of CP20-38-4-3-2 with Tianxuan 54 for sexual hybridization in Tianshui Agricultural Science Research Institute,using genealogy method and directional selection for 12 consecutive years.In 2016—2018,the average yield of Tianxuan 67 was 7095.00 kg/hm^2 and 7.1%higher than that of the control Lantian 33 in Winter Wheat Regional Test in Longnan District.The plant height is 84.2 cm,ear length is 9.3 cm,1000-grain weight is 44.26 g,bulk weight is 819 g/L.The seed crude protein is 123 g/kg,wet gluten is 254 g/kg,sedimentation value is 49 mL,lysine is 3.7 g/kg and total ash is 18 g/kg.The results of inoculated identification of showed that Tianxuan 67 was medium infection to mixture race at the seeding stage,immune to Zhong 4-1,Gui 22-14,CY34,CY33,CY32,other strains of Guinong,and mixture race at the adult stage.It is suitable for growing in the valley areas in Tianshui and Longnan.
