Drought Resistance Identification and Screening of High-quality Millet Varieties in Henan Province
The drought resistance of 23 high-quality millet varieties in Henan Province was identified,providing a basis for the innovation of millet germplasm and the breeding of drought resistant millet varieties in Henan Province.By conducting water stress and non-water stress tests on foxtail millet throughout its entire growth period in a fully automated drought greenhouse,agronomic traits were analyzed.After harvesting,the foxtail millet was threshed and the yield of the plot was weighed.We calculated the drought resistance coefficient and yield drought resist-ance index for each trait,and comprehensively evaluated the drought resistance of different millet varieties.Results showed that the DI value ranged from 0.612 to 1.305.Among them,one variety had extremely strong drought resistance(HR,drought resistance index 1.305),which was Yugu 47.A total of 11 varieties had strong drought resistance(R,drought resistance index 1.000-1.179),which were Zheng 22C1-3,An 20N-3024,Luogu 8,Jingshan 20T-1129,Luoyou 6158,Luogu 7,An 22-GW8389,T2016,Zheng 21Z3976,Zheng 22C17 and Yugu 18.6 varieties had moderate drought resistance(MR,drought resistance index 0.803-0.884).There are 5 varieties with weak drought resistance(S,drought resistance index 0.612-0.787).
