摘要: 以14份来源于美国和我国的玉米自交系为亲本,按照完全双列杂交试验设计配制182个杂交组合,连续3 a分析玉米籽粒蛋白质、淀粉、脂肪、赖氨酸含量4个品质性状的配合力及性状与配合力的关系,为玉米籽粒优质性状改良和新品种选育提供材料及理论依据。结果表明,14份玉米自交系及其组配的182个杂交组合的籽粒蛋白质、淀粉、脂肪含量在3 a间总体上均呈极显著正相关。籽粒蛋白质、淀粉、脂肪、赖氨酸含量一般配合力(GCA)方差均明显大于特殊配合力(SCA)。籽粒蛋白质、淀粉、赖氨酸含量的遗传均以加性效应为主;淀粉含量遗传力最高,为71.82%,其次为赖氨酸含量(69.74%),脂肪含量最低(42.83%)。4个品质性状GCA在不同自交系间差异均极显著,其中,籽粒蛋白质含量、淀粉含量和脂肪含量GCA效应值较大,赖氨酸含量GCA效应值较小。LH202、郑A88、PHR55和郑H71为亲本组配的杂交组合的品质性状SCA效应值较大,品质较优。玉米籽粒淀粉含量与蛋白质、脂肪、赖氨酸含量均呈极显著负相关,而蛋白质、脂肪、赖氨酸含量间均呈极显著正相关;杂交组合4个品质性状分别与父母本GCA效应值之和、SCA效应值呈极显著、显著正相关。

Abstract: Fourteen maize inbred lines from China and America were used to cross 182 combinations according to complete diallel cross design.The combining ability of protein,starch,fat and lysine contents in maize grains and the relationship between the above four traits and combining ability were analyzed for three consecutive years,so as to provide materials and theoretical basis for the improvement of quality traits and breeding of high‑quality maize varieties.The results showed that the contents of protein,starch and fat in grains of 14 maize inbred lines and their 182 hybrid combinations were significantly positively correlated among three years.The variances of general combining ability(GCA)of protein,starch,fat and lysine contents were obviously higher than those of special combining ability (SCA).The genetic effects of protein,starch and lysine contents were mainly additive;starch content had the highest heritability(71.82%),followed by lysine content(69.74%),and fat content(42.83%)was the lowest.There were significant differences in GCA of four quality traits among different inbred lines,the effect values of GCA of protein,starch and fat contents were larger,and that of lysine content was lower.The SCA effect values of quality traits of the hybrid combinations with LH202,ZhengA88,PHR55 and ZhengH71 as parents were higher,and the quality was better. The starch content in maize grain was significantly negatively correlated with protein,fat and lysine contents,respectively,while there were significantly positive correlations among protein,fat and lysine contents;the four quality traits of hybrid combinations were extremly significantly and significantly positively correlated with the sum of parental GCA effect values and SCA effect value,respectively.
