1985年和1986年，在加拿大萨斯卡顿，利用3个双棱麦芽麦系（Hordeum vulgare L.）发育的2个群体，对脱皮的遗传力、变异率和遗传进展进行了研究。种群是Harrington/ ellis和Harrington/WM797-83。在这两个人群中，对遗传率的估计相对较低至中等。结合在亲本系中发现的高变异性，可以得出结论，外壳剥落在很大程度上是受环境影响的性状。遗传进步的估计表明，在严格的选择压力（5%）下，可以实现适度的增益。在F3和F4代中发现了大量的变异，表明通过选择有改进的潜力。根据所获得的结果，对船体粘附性的选择最好纳入已建立的育种计划的后代中。
Two populations, developed from the three two-rowed malting barely (Hordeum vulgare L.) lines, were used to estimate the heritability, varibility, and genetic advance of hull peeling in 1985 and 1986 at Saskatoon, Canada. The populations were Harrington/Ellice and Harrington/WM797-83. In both populations, estimates of heritability were relatively low to moderate. Coupled with high variability found within the parental lines, it was concluded that hull peeling is largely an environmentally influenced trait. Estimates of genetic advance indicated that moderate gains could be achieved with stringent selection pressure (5%) against hull peeling. A great deal of variability was found within the F3 and F4 generations indicating potential for improvement through selection. Based on results obtained, selection for hull adherence would best be incorporated into the later generations of an already established breeding program.
