Abstract：In order to screen out the forage barley varieties with high quality,high yield,wide adaptability,strong stress resistance and excellent comprehensive traits,the comparative analysis of comprehensive traits of the new forage barley lines selected by Dali Bai Autonomous Prefecture Academy of Agricultural Sciences and Technology Extension was studied at the experimental base of the Institute of Food Crops during 2023-2024.The results showed that compared with the control V43,the yield of these 11 new lines increased extremely significantly(P＜0.01),and the increase was between 20.21％and 49.52％.Effective spike,grains per spike and thousand-grain weight are the three factors that affect the grain yield of barley.Among the 11 new lines,Feng 2312,Feng 2305,Feng 2211,Feng 2310,Feng 2218,Feng 2307,a total of 6 new lines have excellent comprehensive performance in terms of high yield,adaptability,stress resistance,disease resistance,and agronomic traits.They possess good application prospect.The results showed that effective spike had a great effect on the yield of these 6 new strains,and the high yield could be achieved by increasing the effective spike and combining the proper grains per spike and thousand-grain weight.
