LMW-GS Identification at Gli-A1/GluA3 Loci in NILs of Wheat Variety Longmai 19
摘要
Abstract
In order to identify LMW-GS at Glu-A3 locus linked with Gli-A1 locus in common wheat variety Longmai 19（L-19,HMW-GS 2＊,7＋9,2＋12）and a pair of NILs（L-19-613 and L-19-626）at Gli-A1 locus with genetic background of Longmai 19 with HMW-GS 5＋10,the materials that L-19,L-19-626 and L-19-613,F2 progeny of L-19/L-19-626 were assayed by a set STS markers of LMW-GS at Glu-A3 locus.The results showed that Glu-A3e amplified specific band in L-19-626 type materials with gliadin Gli-A1m.in L-19 and L-19-613 type materials without gliadin Gli-A1m,Glu-A3c amplified specific band.These results indicated the Gli-A1m at Gli-A1 locus was linked with LGW-GS Glu-A3e at Glu-A3 locus and the undesignated gliadin at Gli-A1 locus in L-19-613 and L-19 were linked with LGW-GS Glu-A3c at Glu-A3 locus.It was possible that quality difference between NILs L-19-626 and L-19-613 was due to LMW-GS gene difference of Glu-A3e and Glu-A3c at Glu-A3 locus.关键词
