寒地水稻RVA谱特征及与直链淀粉含量相关研究
Study on RVA Profile Characteristics of Rice in Cold Region and Correlated with Amylase Content
摘要
Abstract
166 rice germplasm resources of rice in cold region were used as the experimental materials ,RVA profile charac‐teristics and amylose content were determined ,and variation analysis ,correlation analysis and cluster analysis were car‐ried in order to provide theoretical basis for parent selection of rice quality breeding in cold region .The results showed that the variation coefficient of setback was the biggest ,followed by consistence ;there was no significant correlation be‐tween amylose content and breakdown ,and there were significantly positive correlation between other RVA profile char‐acteristics .The experimental materials were divided into 5 groups according to the cluster analysis ,the average of hot paste viscosity ,cold paste viscosity and consistence of group 1 were the largest ;setback and consistence of group 2 were the biggest ;peak viscosity and breakdown of group 3 were the biggest ;breakdown of group 4 was the lowest ,setback was the biggest ;the RVA profile characteristic of group 5 were the smallest ,excepted breakdown .关键词
