冬小麦新品种天选63号是天水市农业科学研究所以周麦11为母本，9595-3-1作父本进行有性杂交，采用系谱法经连续9 a的定向选择而成。在2014 — 2016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6 704.25 kg/hm2，较对照品种兰天25号增产14.95%。该品种株高80.30 cm，平均穗长9.58 cm，千粒重44.30 g，容重789.00 g/L。籽粒蛋白质含量123.0 g/kg(干基)，湿面筋含量211.0 g/kg(14%水分基)，沉淀值36.00 mL(14%水分基)，赖氨酸3.9 g/kg(干基)，总灰分18.0 g/kg(干基)。经接种鉴定，该品种苗期对混合菌表现中感，成株期对条中33号、G22-14、条中32号、条中34号和贵农其它菌系表现免疫，对混合菌表现中抗。适宜在天水市和陇南市川区种植。

Tianxuan 63 is a winter wheat cultivar， bred systematically the parental combination of Zhoumai 11 with 9595-3-1. In 2014 — 2016， the average yield of Tianxuan 63 was 6 704.25 kg/hm2 and 14.95% higher than that of the check in Winter Wheat Regional Test in Longnan district. In addition， the plant height is 80.30 cm， ear length is 9.58 cm， 1000-grain weight is 44.30 g， bulk weight is 789.00 g/L， seed crude protein is 123.0 g/kg， wet gluten is 211.0 g/kg， sedimentation value is 36.00 mL， lysine is 3.9 g/kg and Total ash is 18.0 g/kg. The results of inoculated identification of showed that Tianxuan 63 was medium infection to mixture race at the seeding stage， immune to CY33， G22-14， CY32， CY34， other strains of Guinong， and medium resistant to mixture race at the adult stage. It is suitable for growing in the valley areas in Tianshui and Longnan.
