Ecological Adaptability Assessment of Proso Millet Varieties(Lines)in Arid Mountainous Areas
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.
