摘　　要：以本所大麦高代品系材料及当地主推品系(种)苏啤3号为试验材料,进行饲草利用性能的研究。结果表明:盐07212的鲜质量、干质量均居15个品系(种)的首位;同时,饲草产量与籽粒产量及主要农艺性状的相关性分析表明,鲜质量和干质量与籽粒产量、分蘖数、株高、剑叶面积、倒二叶面积、倒三节直径均呈极显著正相关。The present study evaluated the green fodder yield performance of 14 high generation barley varieties bred in Jiangsu Coastal Area Institute of Agricultural Sciences, and Supi 3 was used as the control, which is a major malting barley variety grown in this area.The 15 barley varieties were investigated by measuring their fresh and dry fodder yields as well as major agronomic traits including tiller number, plant height, stem diameter, leaf size, and leaf stem ratio. Moreover, the correlation analysis was conducted to determine the relationship between the agronomic traits and green fodder yield of the tested barley varieties. The results showed that their fresh and dry fodder yields had a significant negative correlation with their grain yield; but possessed significant positive correlations with tiller number, plant height, flag leaf area, the area of the second leaf from the top, the diameter of the third stem section from the top,and stem mass. These results lay foundations for the selection of two-rowed barley varieties for use as green fodder.
