A strong association between the absence of the granule-bound starch synthase (GBSS) protein for the 4A chromosome of wheat and Japanese Udon noodle quality has been previously described. The aim of this study was to identify a molecular marker linked to the GBSS 4A locus which could be used to identify wheat with the desired texture for Udon noodles. PCR primers were designed to target this gene which gave a 440 bp PCR band, corresponding to the presence or absence of the 4A GBSS gene. Of the 268 genotypes screened with these primers, 267 were correctly identified using the PCR primers. The remaining genotype was shown to be heterogeneous for the marker. The PCR marker test developed has advantages over existing methods used to screen for Udon noodle starch quality as it enables high throughput, accurate tests to be carried out on leaves of young seedlings or mature seed and identify breeding lines that are heterogeneous for the 4A allele which will allow for reselections. Application of this PCR test will speed up selection for Udon noodle quality genotypes and reduce breeding costs for production of noodle wheat varieties.
