用甘木二条等七个二棱大麦品种（ＨｏｒｄｅｕｍｄｉｓｔｉｃｈｕｍＬ）进行半双列杂交，采用胚乳数量性状世代平均数的遗传模型对１９９０年和１９９２年的亲本和Ｆ１所结的种子的粒形、粒重、皮壳率、蛋白质％等性状进行遗传分析。结果表明：与Ｓ－０９６杂交的组合粒重最高，与甘木二条的杂交组合皮壳率低，与黔浙１号的杂交组合粒重较高、粒形较短圆。遗传方差分量的分析结果表明，粒形、粒重和皮壳率性状主要受基因主效应控制，基因×环境互作效应较弱。蛋白质含量主要受种子直接显性效应和母体显性效应控制，直接加性效应、母体显性效应与环境的互作也较强。控制种子粒长的遗传效应主要是母体加性、显性效应以及种子直接加性效应。粒宽、粒厚、粒重和皮壳率则主要受种子基因的直接显性效应控制，其次是种子直接加性效应。文中还分析了各籽粒品质性状的普通直接遗传率和普通母体遗传率及其相关性
The genetic diversity of seven daphn barley varieties (Hordeum distichum L.) was studied by using the genetic model of the average number of generations of endosperm traits. The grain shape, grain weight, Husk rate, protein% and other traits genetic analysis. The results showed that the grain weight of hybrid combination with S-096 was the highest, the hybrid combination with sweet potato two hybrids was low, and the hybrid combination with Guizhou No.1 and Zhejiang No.1 had higher grain weight and shorter grain size. Analysis of genetic variance components showed that the grain shape, grain weight and crustacean rate traits were mainly controlled by the main effect of the gene, and the gene × environment interaction effect was weak. Protein content was mainly controlled by direct dominant effect of seed and dominant effect of maternal, direct additive effect, and maternal dominant effect interacted with environment. The genetic effects controlling grain length are mainly maternal additive, dominant and seed additive effects. Grain width, grain thickness, grain weight, and hull percentage were mainly controlled by the direct dominant effect of seed genes, followed by direct additive effects of seeds. The article also analyzed the general direct heritability and general maternal heritability of each grain quality trait and its correlation
