Abstract

The physio-chemical properties of starch influence the nutritional value and the functional properties of starch containing foods. In this thesis, a population of 233 breeding lines of rice was analysed for variation in 17 rice starch synthesis genes, encoding seven classes of enzymes such as AGPases, GBSSs, SSs, Bes, DBEs, SPHOL and GPT1. This approach employed next-generation sequencing technology followed by a comprehensive association study of 110 functional SNP. SNP loci were analysed for associations with rice pasting and cooking quality. In total, The GBSSI and SSIIa had major influence on starch properties and the other genes had minor associations.
