摘　　要：以18个玉米自交系组配成的16个紫玉米杂交组合为试验材料,研究不同组配方式配制的紫玉米籽粒、穗轴、苞叶、雄穗花青素含量及花青素产量。结果表明:(1)不同组配方式的紫玉米籽粒花青素含量、籽粒产量及籽粒花青素产量差异均较大。深紫玉米×深紫玉米,花青素含量最高;深紫非糯玉米×糯玉米,籽粒产量最高;深紫玉米×深紫玉米,籽粒花青素产量最高。(2)深紫玉米×深紫玉米,穗轴花青素含量、花青素产量最高;非紫苞叶×深紫苞叶,紫玉米苞叶花青素含量、花青素产量最高;非紫雄穗×深紫雄穗,紫玉米雄穗花青素含量、花青素产量最高。(3)穗轴花青素含量与籽粒花青素含量呈极显著正相关;雄穗花青素含量与苞叶花青素含量呈极显著正相关。(4)紫玉米花青素总产量(籽粒、穗轴、苞叶、雄穗)为:深紫×深紫>深紫×浅紫>非紫×深紫>浅紫×非紫;籽粒花青素产量对总花青素产量贡献最大。Content and yield of anthocyanin in grain, cob, bract and tassel of purple corn of different combining types were studied using 16 purple corn hybrids grouped by 18 maize inbred lines. The results showed that：l. Differences of content of grain anthocyanin, grain yield and grain anthocyanin yield of purple corn of different combining types were all great. Content of anthocyanin of Deep Purple corn × Deep Purple corn was the highest; grain yield of Deep Purple non-waxy corn × waxy corn was the highest ; yield of grain anthocyanin of Deep Purple corn x Deep Purple corn was the highest. 2. Yield and content of cob anthocyanin of Deep Purple corn x Deep Purple corn were both the highest ; content and yield of bract anthocyanin of Purple non-bract corn ×Deep Purple bract corn were both the highest; content and yield of tassel anthocyanin of Purple non-tassel corn x Deep Purple tassel corn were both the highest. 3. Content of cob and grain anthocyanin were highly significant positive correlation; content of tassel and bract correlation. 4. Anthocyanin total yield of purple corn （grain anthocyanin were also highly significant positive , cob, husk, tassel） was Deep Purple corn x Deep Purple corn 〉 Deep Purple corn x Shallow Purple corn 〉 non-purple corn x Deep Purple corn 〉 Shallow Purple corn x non-purple corn ; yield of grain anthocyanin made the greatest contributions to total yield of anthocyanin.
