Mapping of QTL for cooking quality traits of rice.

Type: article
Abstract: A recombinant inbred population consisting of 190 lines,derived from the cross of a javanica(D50) and an indica(HB277) rice was used to investigate the genetic factors affecting cooking quality of rice.A total of 102 simple sequence repeat(SSR) markers were used to construct a genetic linkage map spanning 1226.4 cM on total 12 chromosomes,with an average interval of 12.02 cM.By Windows QTL Cartographer 2.5,a total of six quantitative trait loci(QTLs) were identified for the three traits,two for amylose content(AC),one for alkali spreading value(ASV),three for gel consistency(GC).Three QTLs(qAC6,qGC6 and qASV6) could stably express and had significant additive effects in Hangzhou and Hainan.qAC6 and qGC6governing AC and GC respectively were flanked by RM508 and RM587 on the short arm of chromosome 6,and qASV6 governing ASV was flanked by RM111 and RM3438 on the same chromosome.
