摘要： 为了明确谷子的农艺和品质性状，快速鉴定胚乳的粳糯性，以11份谷子品种为材料，利用SAS 9.3软件和I2-IK染色技术，对其农艺和品质性状变异、相关性与籽粒粳糯性进行分析。结果表明，供试谷子品种单穗重的变异系数最大，为20.73%，节间数最小，为6.05%。糯质类型单穗重与单穗粒重和出米率的相关系数均为0.98，单穗粒重与出米率的相关系数为0.97，均达到极显著正相关；非糯类型单穗重与单穗粒重的相关系数为0.99，穗长和穗下节间长与出米率的相关系数分别为-0.94和-0.82，均达到极显著正或负相关。节数与单穗重和单穗粒重均达到显著正相关。非糯类型具有较低的糊化温度、较高的胶稠度和直连淀粉含量。‘杏黄粘’、‘猫爪粘’、‘白米粘谷’等糯质类型I2-IK染色呈红褐色，‘鸭子嘴’、‘金丰谷’、‘丰田501’、‘200106’、‘赤谷9号’和‘9931-2-1-2’等非糯类型呈蓝色。

Abstract: In order to clarity the agronomic and quality characters of millet, and rapidly identify its waxy or no-waxy endosperm, 11 foxtail millet cultivars were used to study the variation and correlation of agronomic and quality characters using SAS 9.3 software, and detect no-waxy and waxy types by I2-IK stains. The results showed that the variation coefficient of single panicle weight was 20.73%, which was the largest among all the traits; the variation coefficient of the number of node was the smallest, which was 6.05%. For waxy types, single ear weight was significantly and positively correlated with grain weight per ear and milled rice rate, their correlation coefficients were both 0.98. Grain weight per ear was also significantly and positively correlated with milled rice rate, their correlation coefficient was 0.97. For no-waxy types, single ear weight was significantly and positively correlated with grain weight per ear, their correlation coefficient was 0.99, but the ear long and Long peduncle were significantly and negatively correlated with milled rice rate, their correlation coefficients were -0.94 and -0.82, respectively. The number of node had extremely significant and positive correlation with single spike weight and single spike grain weight. No-waxy types had lower gelatinization temperature, larger gel consistency and higher direct starch content than waxy millets. Stained in I2-IK, the waxy millet grains such as ‘Xinhuangnian’, ‘Maozhuanian’, ‘Baiminiangu’ turned to be reddish brown, but for non waxy types such as ‘Jinfenggu’, ‘Fengtian501’, ‘200106’, ‘Chigu9’, and ‘9931-2-1-2’, their grains turned to be blue.
