中文摘要:
      为了筛选适于延安地区种植的高产稳产、优质及生产需要的优良糜子品种,试验对引进的25个粳性糜子品种和20个糯性糜子品种进行了连续3 a大田试验示范研究。主要从生育期特性、农艺性状、经济性状3个方面对不同糜子品种进行综合分析。结果表明:45个糜子品种都有较强的抗寒性、抗冻性,所有糯性糜子品种都有中等抗旱性,25个粳性糜子品种除陇糜5号、榆糜3号、陇糜7号、陇糜8号、陇糜9号、陇糜10号、陇糜11号、榆糜2号具有较强抗旱性以外,其余抗旱性都处于中等水平。内糜7号、晋黍7号、晋黍5号的千粒重连续3 a不但稳定而且高于其余糯性糜子品种;晋黍5号产量表现出稳定高产的特性;此外,晋黍1号和内糜8号产量虽有波动但平均产量仍保持在较高水平。粳性糜子品种榆糜3号的生育期为77.00 d,内糜1号的生育期仅为58.33 d,在所有品种中最短,其余粳性糜子品种的生育期都介于这两者之间;榆糜3号产量在粳性糜子品种中仅次于内糜9号,内糜9号的平均千粒重和产量都是所有粳性糜子中最高的,产量达 3 256.7 kg/hm2。总的来说,45个糜子品种均能够在延安地区正常生长;但各品种的性状间存在差异,在生产中可根据不同的种植需求进行有针对性的品种选择。此研究结果可为陕北地区糜子品种的选择提供一定的理论依据。
英文摘要:
      In order to screen broomcorn millet varieties with high and stable yield, high quality and suitable for planting in Yan'an area. In this experiment, 25 japonica varieties and 20 waxy varieties of broomcorn millet were tested and demonstrated in the field for three consecutive years.The different broomcorn millet varieties were mainly analyzed from three aspects of growth period characteristics, agronomic traits, and economic traits.The results showed that 45 broomcorn millet varieties had strong cold resistance and strong frost resistance.All waxy broomcorn varieties had moderate drought resistance.Except for Longmi No. 5, Yumi No. 3, Longmi No. 7, Longmi No. 8, Longmi No. 9, Longmi No. 10, Longmi No.11, and Yumi No. 2, all the japonica millet varieties had strong drought resistance, and the rest of them had medium level in drought resistance.The thousand-grain weight of Neimi No. 7, Jinshu No. 7, and Jinshu No. 5 was not only stable for 3 consecutive years, but also higher than other waxy broomcorn millet varieties.The yield of Jinshu No. 5 was stable and high in yield characteristics.In addition, the yield of Jinmi No.1 and Neimi No.8 fluctuated, but the average yield was still at a relatively high level.The growth period of Yushu No. 3 was 77 days, and the growth period of Neimi No. 1 was only 58.33 days. Neimi No. 1 was the shortest among all japonica broomcorne millet varieties, and the growth period of other japonica broomcorne millet varieties was between these two. The yield of Yumi No. 3 was second to Neimi 9 in the japonica broomcorn millet. The average thousand-grain weight and yield of Neimi No. 9 were the highest among all japonica broomcorn millet, with a yield of 3256.7 kg·hm-2.In general, all 45 broomcorn millet varieties can grow normally in Yan'an area,but there are differences in the traits of each variety. In the production, targeted varieties can be screened out according to different planting needs.The results of this study can provide a certain theoretical basis for the selection of broomcorn millet varieties in northern Shaanxi.
