为筛选出环县旱作农业区生态适应性强的糜子新品种，2023年对引进的10个糜子品种(系)在环县干旱山区进行品比试验。结果表明，供试品种(系)产量差异明显，折合产量高于对照品种陇糜10号(2 110.5 kg/hm2)的品种有6个，其中以1104-2-2N最高，为2 555.6 kg/hm2，较陇糜10号增产21.1%(P <0.05)；其次是2012FMZ8-1-3，为2 388.9 kg/hm2，较陇糜10号增产13.2%(P < 0.05)；0903-1-1N、1126-7、2013FMZ3-1-3、1119-4-4-2分别较陇糜10号增产10.5%、7.9%、5.3%、2.6%。其余3个品种(系)的折合产量均低于陇糜10号，以晋黍8号最低，为1 944.4 kg/hm2，较陇糜10号减产7.9%，但与陇糜10号差异不显著(P >0.05)。综合参试品种(系)的生态适应性及经济性状和产量表现，1104-2-2N、2012FMZ8-1-3、0903-1-1N、1126-7、2013FMZ3-1-3、1119-4-4-2等6个品种可在生产中应用。

To select proso millet varieties with strong ecological adaptability in the dry farming area of Huan County, a comparative trial was conducted on 10 introduced proso millet varieties(lines) in the arid mountainous area of Huan County in 2023.The results showed significant differences in yield among the tested varieties(lines). 6 varieties had higher yields than the control variety Longmi 10 (2 110.5 kg/ha), with 1104-2-2N having the highest yield at 2 555.6 kg/ha, an increase of 21.1% compared to Longmi 10(P < 0.05). The second highest was 2012FMZ8-1-3 with 2 388.9 kg/ha, an increase of 13.2% compared to Longmi 10(P < 0.05). The yields of 0903-1-1N, 1126-7, 2013FMZ3-1-3, and 1119-4-4-2 increased by 10.5%, 7.9%, 5.3%, and 2.6%, respectively compared to Longmi 10.The remaining 3 varieties(lines) had lower yields than Longmi 10, with Jinshu 8 having the lowest yield at 1 944.4 kg/ha, a decrease of 7.9% compared to Longmi 10, but the difference was not significant(P>0.05). Considering the ecological adaptability, economic traits, and yield performance of the tested varieties(lines), 6 varieties, i.e., 1104-2-2N, 2012FMZ8-1-3, 0903-1-1N, 1126-7, 2013FMZ3-1-3, and 1119-4-4-2, can be applied in production.
