冬小麦新品种天选58号选育报告
|
摘要
冬小麦新品种天选58号为天水市农业科学研究所小麦抗锈育种中心以天817为母本,天选40号为父本进行有性杂交,采用系谱法经连续的定向选择而成。在2013—2015年甘肃省陇南片区域试验中,折合产量6 619.50 kg/hm~2,较对照品种兰天25号增产7.20%。该品种株高100.00 cm,穗长平均8.50 cm,千粒重44.00 g,容重790.00 g/L。籽粒粗蛋白含量12.87%,湿面筋含量22.70%,沉降值45.00 mL,赖氨酸含量0.36%,粗灰分1.7%。经接种鉴定,苗期对条锈混合菌表现中抗,成株期对供试菌系及混合菌表现中抗至高抗,总体表现抗病。适宜在天水市、陇南市河谷川道区种植。
Tianxuan 58 is a systematically-bred winter wheat cultivar by sexual hybridization with the parental combination of Tian 817/Tianxuan 40,bred by Tianshui Institute of Agricultural Sciences.The average yield of Tianxuan 58 is 6 619.50 kg/hm~2,which is 7.20% higher than the check Lantian 25 in 2013 — 2015 winter wheat regional test in the Longnan district.In addition,the plant heigth is 100.00 cm,ear length is 8.50 cm,1 000-grain weight is 44.00 g,bulk weight is 790.00 g/L,seed crude protein content is 128.7 g/kg,wet gluten content is 227.0 g/kg,settlement value is 45.00 mL,lysine content is 3.6 g/kg,coarse ash is 17.0 g/kg.By inoculating identification,the results show that Tianxuan 58 is medium resistant to the mixture race of wheat stripe rust at the seeding stage,it is medium resistant to test strains and mixed bacteria at the adult stage.On the whole,it is resistant to wheat stripe rust.It is suitable to be grown in the valley area of Tianshui city and Longnan city.
