| 摘 要： | 以9份糯玉米自交系为材料，采用NCⅡ遗传交配设计，配制4×5不完全双列杂交组合，基于鲜子粒冻干、磨粉方式，采用近红外检测技术测定6种呈味游离氨基酸含量。结果表明，糯玉米组合呈味氨基酸变幅为0.13～8.05 g/mg，脯氨酸含量最高；WX156、WX159等改良系具有较高的呈味氨基酸一般配合力(GCA)。筛选得到B17×WX159、B13×WX156等高呈味氨基酸含量组合。相关分析表明，可溶性糖、皮渣率及谷氨酸含量与糯玉米口感紧密相关。

| Abstract: | Nine waxy corn inbred lines were used as materials,and 4×5 incomplete diallel cross combinations were formulated in NCII genetic cross design.Based on the fresh seeds freeze-drying and milling method,the content of six flavoring free amino acids was determined by near-infrared detection technology.The results showed that the flavor amino acids in the waxy corn combinations varied from 0.13 to 8.05 g/mg and had the highest proline content;the improved lines such as WX156 and WX159 had high general cooperativity (GCA) of flavor amino acids;the combinations with high flavor amino acid content such as B17×WX159 and B13×WX156 were screened;the correlation analysis showed that soluble sugar,tare rate and glutamate content were closely related to the taste of waxy corn. |
