[目的]选育适合辽西干旱区种植的谷子新品种。[方法]以“金锤谷”和“奇丰谷”的自然变异株为材料,对其进行南繁北育连续5 个世代的定向系统选育,经过品种初试、中试和推广种植示范,选育出耐旱、抗倒、高产、优质谷子新品种。[结果]朝新谷 2 号和 5 号一般单产 6 750.0～ 8 250. 0 kg / hm2,高产可达9 000.0 kg/hm2以上; 2 个品种全生育期需要≥10.0 ℃积温2 000 ～2 800 ℃,需水量260 ～340 mm,日照时间800 ～1 200 h; 大粒粟,米色金黄,米味醇香,适口性极好,外观品质和商品品质极佳; 抗旱、抗倒、耐瘠薄,较抗锈病、白发病和黑穗病等多种病害。2005～ 2007 年 2 个品种在辽宁省累计推广面积达 15. 0 万 hm2,推广覆盖率占该省3 年谷子总面积的42.3%。[结论]朝新谷2 号和5 号的推广应用,为半干旱地区农民充分利用地区气候资源提供了新途径。
[Objective] Breeding new millet varieties suitable for planting in the arid area of western Liaoning. [Method] With the natural variant strains of “Golden Hammer Valley” and “Qi Feng Valley” as material, the breeding of directional system of five generations of South Fanghuai continuous five generations was conducted, Promote planting demonstration, breeding a drought-resistant, anti-down, high-yield, high-quality millet new varieties. [Result] The yield of 62800.0 ~ 8 250. 0 kg / hm2 and the yield of 9000.0 kg / hm2 were the highest in Xinxue 2 and 5 respectively. The accumulative temperature of the two cultivars was ≥10.0 ℃ and the accumulated temperature was 2000 ~ 2000 ℃ , Water requirement 260 ~ 340 mm, sunshine time 800 ~ 1200 h; large grain millet, golden beige, rice flavor mellow, palatability is excellent, appearance quality and excellent product quality; drought, lodging, barren, , White hair and smut and other diseases. From 2005 to 2007, the two cultivars in Liaoning Province had a total area of 150,000 hectares to be popularized, covering 42.3% of the total area of three-year millet in the province. [Conclusion] The popularization and application of Northward Valley 2 and 5 provided a new way for farmers in semi-arid area to make full use of regional climate resources.
