稻米淀粉RVA谱特征值与直链淀粉、蛋白含量的相关性及QTL定位分析
Correlation Analysis and QTL Mapping for Starch RVA Profile Properties and Amylose and Protein Contents in Rice
摘要
Abstract
[Objective]The detection of new quantitative trait loci(QTLs)and the correlation analysis between different rice quality traits are used to dissect the genetic mechanism underlying rice quality and to breed high-quality rice varie-ties.[Method]The backcross inbred lines(BILs)of Sasanishiki× Habataki planted in two environments were used to detect additive QTLs for amylose content,protein content and RVA profiles.[Result]Phenotypic analysis showed the protein content of Habataki was higher than that of Sasanishiki while other rice quality parameters of Sasanishiki were generally higher than those of Habataki except the setback viscosity.A total of 42 additive QTLs were detected,and ten of them could be repeatedly detected in two environments,including qPC8 ,qAC4 ,qAC10 ,qPKV2 ,qPKV7 , qH PV7 ,qCPV1 ,qBDV4 ,qBDV7 and qSBV7 .Of them,qCPV1 ,qBDV4 ,qPKV7 ,qH PV7 and qAC10 had not been reported previously.Moreover,the environmental stability of 10 QTLs,was further confirmed across two differ-ent environments by chromosome segment substitution lines(CSSLs).[Conclusion]Significant correlations were ob-served between RVA profiles and protein or amylose contents,and many QTLs affecting different quality traits were co-localized.关键词
