冬小麦新品种天选63号选育报告

Report on Breeding of New Winter Wheat Cultivar Tianxuan 63

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9a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,2a平均折合产量6704.25kg/hm^2,较对照品种兰天25号增产14.95%。该品种株高80.30cm,平均穗长9.58cm,千粒重44.30g,容重789.00g/L。籽粒蛋白质含量123.0g/kg(干基),湿面筋含量211.0g/kg(14%水分基),沉淀值36.00mL(14%水分基),赖氨酸3.9g/kg(干基),总灰分18.0g/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/hm^2 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.
