RVA分析辅助选择食用优质早籼稻的研究
Assisted-selection for Early Indica Rice with Good Eating Quality by RVA Profile
摘要
Abstract
Rapid Visco Analyzer (RVA) was used to investigate different early indica rice varieties. The result showed that, according to obvious differences in setback and breakdown, it could not only distinguish different apparent amylose content of varieties rapidly, but also identify the superior or inferior eating quality of rice varieties with intermediate AAC effectively. The analysis for interfering factors indicated that high-temperature pretreatment, brown rice and water resources might affect the RVA profile more or less, but not affect the evaluation. However, the sample quantity seriously influenced the testing result. Upon this basis, an optimized RVA testing system, more suitable for assisted-selection in breeding practice, was formulated. Using the characteristics of RVA profile as physical/chemical selection indicators, several superior quality rice strains were successfully screened from the progenies derived from the crosses between early indica rice and single cropping indica rice or javanica rice.关键词
