近年来,陇东旱塬冬麦区条锈病由偶发区变为常发区,当前一些主栽品种因其抗锈性差而减产,播种面积逐年降低。选育抗条锈、丰产、优质的接班新品种势在必行,为此省科委在“七五”期间组织了“冬小麦抗锈、丰产、优质新品种选育”协作攻关项目,省农科院镇原试验站承担了本课题,经过几年的努力,选育出优良品种陇鉴46。在1990年6月通过省级技术鉴定验收,专家评议认为本项研究达到省内先进水平,尤其是抗锈水平为国内先进,该品种于1991年8月审定定名。
In recent years, the stripe rust in Dongmao area of Longdong dryland has changed from sporadic area to frequently-occurring area. At present, some main cultivars have reduced production due to poor rust resistance and the sown area has been decreasing year by year. Breeding resistance to stripe rust, high yield, high quality new succession is imperative, this province Science and Technology Commission in the “Seventh Five-Year” period organized a “winter wheat rust, high yield, breeding new varieties of high quality” collaborative research projects, provincial agriculture ASTRI Zhenyuan experimental station assumed the task, after several years of efforts, bred a good variety Longxian 46. In June 1990, it passed the provincial technical appraisal and acceptance. According to the experts’ appraisal, the study reached the advanced level in the province, especially the anti-rust level was advanced in China. The variety was approved in August 1991.
