摘要:

出米率是反映糜子商品性的重要指标。为了探究糜子出米率的影响因素及相关性,并为糜子种植和加工提供科学指导,本研究以23个优质糜子品种为研究对象,在定边、鄂尔多斯、会宁、延安4个试点进行种植试验。糜子收获后统一加工制成黄米,计算(统计)出米率,并对品种、试点和粒色3个因素对糜子出米率的影响及相关性进行分析。结果表明,在参试品种中,粳性组‘固糜21号’出米率最高,为75.25%;糯性组‘固糜25号’出米率最高,为79.25%。在不同试点中,鄂尔多斯试点的糜子出米率最高,为73.13%。在定边,粳性与糯性糜子之间的出米率存在显著差异;在鄂尔多斯和会宁,粳性与糯性糜子之间的出米率存在极显著差异。粒色分析显示,白色糜子的出米率显著高于其他颜色,为77.55%。相关性分析结果表明,糜子的品种和粒色与出米率呈现出显著负相关,试点和出米率呈现出负相关但未达到显著水平。综上所述,不同品种、试点和粒色均对糜子的出米率产生影响,其中品种和粒色与糜子出米率显著负相关。本研究结果可为糜子生产中的品种的选择和区域布局提供一定的理论依据。

Abstract:

The milled millet rate is an important index reflecting the marketability of broomcorn millet. To explore the influencing factors and correlations of the milled millet rate of broomcorn millet, and provide a guiding basis for the planting and processing of broomcorn millet, this study took 23 high-quality broomcorn millet varieties as research objects, which were planted in 4 experiment sites including Dingbian, Ordos, Huining and Yan'an. After harvesting, the broomcorn millet was uniformly processed into glutinous millet, the milled millet rate was calculated, and the effects and correlations of three factors (variety, experiment site and grain color) on the milled millet rate of broomcorn millet were analyzed. The results showed that among the tested japonica broomcorn millet group, ‘Gumi 21’ had the highest milled millet rate of 75.25%; among the glutinous broomcorn millet group, ‘Gumi 25’ had the highest milled millet rate of 79.25%; the Ordos site had the highest milled millet rate of 73.13%. There were significant differences in the milled millet rate between japonica and glutinous broomcorn millet in Dingbian (P<0.05), and extremely significant differences in the milled millet rate between japonica and glutinous broomcorn millet in Ordos and Huining (P<0.01). Grain color analysis showed that the milled millet rate of white broomcorn millet was significantly higher than that of other colors, reaching 77.55%. The variety and grain color of broomcorn millet showed a significant negative correlation with the milled millet rate, while the experiment site showed a negative correlation with the milled millet rate but no significance. Different varieties, pilot sites and grain colors all had effects on the milled millet rate of broomcorn millet, and the variety and grain color had a significant negative correlation with the milled millet rate, which can provide a certain theoretical basis for the selection of broomcorn millet varieties in production.

Key words: broomcorn millet, milled millet rate, variety, correlation
