摘　　要：依据１９８９年（４×４）和１９９０年（６×６）两套双列杂交试验资料用Ｈａｙｍａｎ方法对高粱籽粒总蛋白及其４种组分含量进行了遗传效应分析。结果表明，总蛋白、清蛋白、谷蛋白和醇溶谷蛋白含量两年试验结果均符合加性—显性模型，球蛋白含量在１９８９年符合加性—显性模型。加性效应和显性效应对各性状均有重要影响，但也存在一定差别：总蛋白和清蛋白含量为加性效应＞显性效应，为部分显性；球蛋白含量加性效应与显性效应相当，属完全显性；谷蛋白和醇溶谷蛋白含量两年结果不一致，谷蛋白含量在１９８９年，醇溶谷蛋白含量在１９９０年为加性效应＞显性效应，呈部分显性，但二者分别在１９９０年和１９８９年又为显性效应＞加性效应，呈超显性。除醇溶谷蛋白含量显性方向指向增效外，其余４个性状的显性方向均指向减效。清蛋白和球蛋白含量正负基因频率分布在两年均呈对称性，而总蛋白、谷蛋白和醇溶谷蛋白含量的正负基因频率分布在１９８９年和１９９０年分别表现为对称和不对称性。各性状的显性控制基因组数均为１组，狭义遗传力均较低。Genetic effects of crude protein (CP),albumin (AL),globulin (GLO),glutelin (GLU),prolamin (PRO) contents in Chinese Sorobum were analysed by using Hayman model based on the data from 1989(4×4)and 1990(6×6) diallel crossings.The results indicated that, the adequacy of additivedominant was shown to CP, AL,GLU and PRO contents both in 1989 and in 1990,and to GLO content only in 1989.There were partial dominance with CO and AL contents,complete dominance with GLO content,overdominance with GLU (1990) and PRO(1989)contents and partial dominance with GLU(1989) and PRO(1990).The dominant direction direction for CP,AL,GLO and GLU contents was on the decrease,but that for PRO content was on the increase.The distribution of positive and nigative gene frequency behaved a symmetry for AL and GLO contents both in 1989 and in 1990, and for CP,GLU and PRO contents IN 1989,with the exception of CP,GLU and PRO contents which behaved an unsymmetry in 1990.the number of dominant gene group was 1 for all traits.The narrow heritabili ties were also relatively low for all of the 5 traits.
