抗条锈高产优质冬小麦新品种陇鉴108选育报告

Report on New-bred Winter Wheat Cultivar Longjian 108 with Resistance to Stripe Rust, High-yielding and High-quality

冬小麦新品种陇鉴108(原代号B23)为甘肃省农业科学院旱地农业研究所以长武134为母本、临远3158为父本进行有性杂交,经过多年系谱法选育而成。2011—2013年参加甘肃省冬小麦区域试验,2 a 11点(次)平均折合产量为5 059.2 kg/hm^2,较对照品种西峰27号增产12.08%;2013—2014年度参加甘肃省冬小麦生产试验,5个试点平均产量为5 265.0 kg/hm^2,较对照品种西峰27号增产13.5%,增产极显著。陇鉴108属冬性普通小麦,生育期265~278 d,平均株高为92.0 cm,平均穗粒数39粒,平均千粒重为40.6 g,平均容重为801.3 g/L。籽粒含粗蛋白(干基)15.66%、湿面筋33.0%,沉淀指数(14%湿筋)39.0 mL,面团形成时间3.5 min。抗旱性、抗寒性强,对供试条锈菌种免疫,丰产、稳产性好,适应性广。适宜在甘肃省陇东地区与陇中地区种植,同时也可在宁夏的固原市、泾源县及彭阳县等同类型区山旱地种植。

Longjian 108(the original code of B23)is a newly bred winter wheat cultivar by parental combination of Changwu 134 with Linyuan 3158.In 2011-2013,the average yield in 2 a 11 sites(times)is 5 059.2 kg/hm2,increased by 12.8%compared with the control cultivars Xifeng 27 in Gansu provincial winter wheat regional test.In 2013-2014,the average yield of 5 plots is 5 265.0 kg/hm2,increased by 13.5%compared with the control cultivar Xifeng 27 in Gansu provincial winter wheat production test.The growth period of Longjian 108 is 265~278 days,the average plant height is 92 cm,the average grain number is 39 grains,the average 1 000-grain weight is 40.6 g,and the average bulk density is 801.3 g/L.The crude protein content of grain is 15.66%,wet gluten content is 33%.The sediment index(14%wet gluten)is 39.0 mL,dough formation time is 3.5 min.The results indicate that the drought resistance and cold resistance of Longjian 108 is significant.It is immune to the current epidemic of stripe rust,with high and stable yielding ability,as well as wide adaptability.It is suitable to be grown in the eastern and middle regions of Gansu province and the similar ecological dryland areas in Ningxia.
