摘 要 ：对六棱大麦杂种 F_120个组合及其9个亲本12个性状的杂种优势研究表明:株粒重、单株草重、株粒数和每穗粒重的杂种优势达20～35%;主穗长、株高、单株穗数、每穗粒数、千粒重和主穗粒数的杂种优势约为10～20%;主穗小穗数为5.49%,经济系数为负向优势-1.62%。由于各性状的遗传变异均以基因的加性效应为主,各性状的遗传力较高,故预

Abstract:A incomplete diallel cross of 5×4 was designed for this study.Theheterosis and combining ability of 12 characters of 20 F_1 hybrids in 6—row barley were investigated.The kernel weight per plant,grass weight per plant,number ofkernels per plant and kernel weight per spike were remarkably manifested
