摘要:

为评价不同糯玉米品种食味品质的差异,筛选出具有优异食味品质的糯玉米种质。本研究以不同来源的19个鲜食糯玉米品种为试验材料,测定19个鲜食糯玉米品种的果皮性状、籽粒含水量、可溶性糖含量、淀粉黏度RVA特征值和淀粉含量等17个食味品质性状,利用变异分析、相关性分析和主成分分析,建立糯玉米食味品质综合评价模型,筛选食味品质优异的糯玉米品种。结果显示,19个玉米品种的峰值黏度、终值黏度、消减值和回复值等淀粉黏度RVE特征值指标具有较大变异系数并显著相关,且在主成分1中占有较高载荷,可较好地反映糯玉米食味品质差异;统计19个玉米品种的综合评分值发现,‘YN811’、‘291’和‘京糯832’的主成分综合评分值和食味品尝得分值均较高。综上,峰值黏度、终值黏度、消减值和回复值等淀粉黏度RVE特征值为鉴定糯玉米食味品质的关键评价指标,‘YN811’、‘291’和‘京糯832’是具有较佳食味品质的优质糯玉米品种。

Abstract:

The aims were to evaluate the eating quality difference of different waxy corn varieties, and screen the germplasm of waxy corn with excellent eating quality. In this study, 19 fresh waxy corn varieties from different sources were used as experimental materials, 17 eating quality traits included peel traits, grain water content, soluble sugar content, starch viscosity RVA characteristic values, and starch content were determined in 19 fresh waxy corn varieties. Variation analysis, correlation analysis, and principal component analysis were used to establish a comprehensive evaluation model for eating quality of waxy corn and screen the waxy corn varieties with excellent eating quality. The results showed that starch viscosity RVE characteristic values, such as peak viscosity, final viscosity, setback viscosity, and consistence viscosity among 19 waxy corn varieties had large coefficient of variation, significant correlation with each other, and occupied a high load in principal component 1, which could better reflect the difference of eating quality of waxy corn. The comprehensive score values of 19 waxy corn varieties showed that ‘YN811’ ‘291’ and ‘Jingnuo 832’ had higher principal component comprehensive scores and taste scores. In conclusion, the starch viscosity RVE characteristic values, such as peak viscosity, final viscosity, setback viscosity, and consistence viscosity, are the key evaluation indexes for identifying the eating quality of waxy corn. ‘YN811’ ‘291’ and ‘Jingnuo 832’ are the high-quality waxy corn varieties with better eating quality.
