摘要
Rice(Oryza sativa L.),one of the important cereal crops,is the major stable food for more than 50% population in the world. Increasing rice grain yield is a crucial challenge,and improving its eating and cooking quality(ECQ) is also an important breeding goal. Starch is the major storage material in rice seeds,which comprises two main types of glucan homopolymer: amylose and amylopectin. The eating and cooking qualities of rice grain are closely related to the ratio of amylose to amylopectin and the architectural features of amylopectin. For improving the ECQ of cultivated species in Northeast of China,the apparent amylose content(AAC) and Rapid Visco Analyser(RVA) profile of 130 rice varieties were measured; nine rice varieties showed highly starch quality were used as donor candidates,and hybridized with the cultivated specie Longjing26 in Northeast of China expecting ultimately to obtain the superior rice variety. Meanwhile,we hope to find some quantitative trait loci(QTLs) related to the starch quality by constructing Recombinant Inbred Line(RIL). Now,some AAC related QTLs have been found by mapping the Recombinant Inbred Line of RCC147 x Longjing26; next,we hope to use those QTLs to improve ECQ of Longjing26
