Adaptability Evaluation of Different Grain Sorghum Varieties in Longdong Region
In order to screen out new sorghum varieties suitable for planting in Longdong region(high altitude,dry),this study introduced 10 grain sorghum varieties to plant in Pingliang,observed and recorded agronomic traits such as flowering,maturity,spike shape,ear type and shell color during the whole growth period,and analyzed plant height,stem diameter,leaf number,yield and disease resistance.The results showed that Jiza193,Liaoza68 and Jinzhong104 were suitable for large-scale cultivation in Longdong region,and the yield was 541.30kg/667 m2,524.26 kg/667 m2 and 508.52 kg/667 m2,respectively.Jinnuoliang10,Fengza88,Liaonuoliang2,Quanliang5,Benuo5,Shenza13 and Jinza118 were not the most ideal varieties for disease resistance,lodging resistance and plant height.
