【摘要】 利用重组自交系群体对淀粉粘度性状与馒头品质间的关系进行了全面分析。相关分析表明,峰值粘 度、低谷粘度、最终粘度、反弹值、峰值时间均与馒头外观、结构、弹韧性、粘性、总分等5项指标呈显著正相关;回归分 析结果表明,粘度性状与馒头品质间存在较强的线性关系,建立了馒头体积、比容、结构、弹韧性、粘性和总分与淀粉 粘度性状的回归方程;通过通径分析明确了各粘度性状对馒头品质的直接效应和间接效应。更多还原

【Abstract】 The relationship between starch viscosity traits of wheat and steamed bread quality was studied using the population of recombinant inbred lines (RILs) as materials. The results of simple correlation analysis show that peak viscosity, trough viscosity, final viscosity, setback, and peak time are significantly and positively correlative to steamed bread appearance, structure, elasticity, viscosity, and total score. The results of stepwise multiple regression show a linear correlation between viscosity traits and steamed bread quality; and linear regression equations are established between them. Direct and indirect effects between viscosity traits and steamed bread quality are revealed by using path coefficient analysis.更多还原
