采用典型相关对啤酒大麦F2代群体的5个产量性状和8个形态性状进行分析,结果表明,穗粒数、千粒重对单株产量的提高有促进作用;单株穗数、叶片数、旗叶面积与单株产量亦密切相关;株高、穗长对穗粒数有正向效应;株高、芒长、主茎节数,叶片数利于提高单株穗数与穗粒重,其它性状作用甚微。综合分析得出:单株穗数多、穗粒数多、千粒重高、半矮秆、叶片数多、旗叶面积大的类型,可作为啤酒大麦F_2代单株选择模式。
Typical correlations were used to analyze the five yield traits and eight morphological traits in F2 generation of barley. The results showed that the number of grains per spike and the 1000-grain weight had an effect on the yield per plant. The number of panicle per plant, number of leaves, The area and the yield per plant were also closely related. The plant height and spike length had a positive effect on the number of spikelets per plant. The plant height, the length of mans, the number of main stems, Little. The results showed that the type of F_2 generation per plant of beer barley could be used as the model of beer barley with more spikes per plant, more grains per spike, higher 1000-grain weight, more semi-dwarf stalks, more leaves and more leaf area.
