冬小麦新品种天选59号选育报告
|
摘要
冬小麦新品种天选59号为天水市农业科学研究所小麦抗锈育种中心以自育高代品系912-1-2-2为母本,农家品种三属麦1号为父本进行有性杂交,采用系谱法经连续定向选择而成。在2013—2015年度甘肃省陇南片区域试验中,平均折合产量6 681.75 kg/hm~2,较对照品种兰天25号增产8.10%。该品种株高84 cm左右,穗长平均8.10 cm,千粒重40.80 g,容重736.00 g/L。籽粒粗蛋白含量135.7 g/kg,湿面筋含量239.0 g/kg,沉降值38.00 mL,赖氨酸含量4.0 g/kg,粗灰分17.7 g/kg。经接种鉴定,苗期对混合菌表现中抗,成株期对条中32号、条中34号、贵农其它及混合菌表现中抗,对贵22-14、条中33号表现免疫。主要适应于天水市、陇南地区河谷川道区种植。
Tianxuan 59 is a systematically-bred winter wheat cultivar by sexual hybridization with the parental combination of salf-fertile advanced line 912-1-2-2/Landraces Sanshumai 1,bred by Tianshui Institute of Agricultural Sciences.The average yield of Tianxuan 59 is 6 681.75 kg/hm~2,which is 8.10% higher than the check Lantian 25 in 2013 — 2015 winter wheat regional test in the Longnan district.In addition,the plant height is 84.00 cm,ear length is 8.10 cm,1 000-grain weight is 40.80 g,bulk weight is 736.00 g/L,seed crude protein content is 135.7 g/kg,wet gluten content is 239.0 g/kg,settlement value is 38.00 m L,lysine content is 4.0 g/kg,coarse ash is 17.7 g/kg.By inoculating identification,the results show that Tianxuan 59 is medium resistant to the mixture race of wheat stripe rust at the seeding stage,it is medium resistant to CY 32,CY 34,Guinong and others mixed bacteria,and it is immune to Gui 22-14 and CY 33 at the adult stage.It is suitable to be grown in the valley area of Tianshui city and Longnan city.
