摘要
兰天17号是通过有性杂交系统选育而成的冬小麦新品种,其杂交组合为92R137/兰天6号,母本含Yr26抗条锈基因。2003、2004年在天水川区组区域试验中,折合平均产量7 614.8 kg/hm2,较对照品种兰天6号增产11.07%;该品种在条锈菌接种鉴定中,苗期对混合菌免疫至高抗,成株期对所接小种及混合菌全部免疫,高抗条锈病兼抗白粉病;经甘肃省农业科学院农业测试中心检测,其籽粒含粗蛋白15.34%、赖氨酸0.5%、粗脂肪2.0%、粗淀粉63.22%、灰分1.67%、湿面筋29.10%,沉降值60 ml;主要适宜在甘肃陇南、天水川区种植。
Lantian 17 was a new winter wheat cultivar bred systematically by crossing with the parental combination of 92R137/Lantian 6. Female parent carried Yr26. The average yield of Lantian 17 is 7 614. 8 kg/hm^2 and 11.07% higher than that of the check Lantian 6 in winter wheat regional experiment which was conducted during the period 2003-2004 in the valley area of Tianshui. Lantian 17 has the characteristics of high resistance to stripe rust and resistance to powdery mildew. By inoculating identification, more definte result was showed that this cultivar was immune or highly resistant to stripe rust at the seedling stage and immune completely at the adult stage. The testing results from the Testing Center of Gansu Academy of Agricultural Science also indicated that seed crude protein, lysine, crude oil, crude starch, ash, wet gluten, and SDS-sedimentation value were 15.34% ,0. 5% ,2.0% ,63.22%, 1.67%, 29.0% and 60 ml, respectively. Lantian 17 was suitable for growing in the valley area of Tianshui and Longnan city.
