山西谷子地方品种的品质分析与综合质量评估
Quality analysis and comprehensive quality evaluation of foxtail millet landraces in Shanxi
摘要
Abstract
[Objective]Foxtail millet is an important coarse cereal crop,characterized by its tolerance to poor soils,drought resis-tance,and short growth period.The dehulled grains,commonly known as millet,are rich in protein,fat,carbohydrates,di-etary fiber,and essential trace elements,offering high nutritional value.With increasing public awareness of health and quality,screening high-quality foxtail millet varieties has become crucial.The quality of foxtail millet is determined by evaluation index-es such as appearance,cooking flavor quality,and nutritional quality.However,comprehensive quality analysis and integrated quality assessment of a large number of local varieties remain limited,restricting the screening and breeding of high-quality fox-tail millet.[Methods]A total of 312 foxtail millet landraces from various growing regions in Shanxi Province were selected for quality analysis.Four appearance quality indexes,seven cooking flavor quality indexes,and three nutritional quality indexes were measured.Multivariate statistical analyses including genetic diversity analysis,correlation analysis,and principal compo-nent analysis were conducted to calculate comprehensive scores for the three quality categories and perform an integrated quality assessment.[Results]The genetic diversity index showed that all quality indexes were greater than 1.00,ranked as follows:starch content>trough viscosity>disintegration value>peak viscosity>final viscosity>protein content>recovery value>L*>pasting temperature>yellow pigment content>CCI>pasting time>a* value>b* value,indicating rich genetic variation in qual-ity-related traits among the different landraces.Correlation analysis revealed that higher starch and yellow pigment content in the 312 foxtail millet varieties were associated with yellower grain color(appearance quality),better gelatinization properties(cooking quality),and improved palatability,further demonstrating a close relationship among appearance,cooking,and nutri-tional quality.Principal component analysis reduced the 14 indicators to six principal components,with a cumulative contribu-tion rate of 85.12%,effectively capturing the quality-related information of the landraces."Little Red Valley"(Xiaohonggu)from Qinyuan County,Changzhi City,ranked first in the comprehensive evaluation.[Conclusion]The integrated assessment of 14 quality indexes across 312 foxtail millet varieties indicated that"Little Red Valley"from Qinyuan exhibited the highest quali-ty and could be used as parental material for breeding superior foxtail millet varieties in future studies.关键词
