Abstract
The property of starch in wheat(Triticum aestivum L.) grain endosperm is a very important determinant for wheat quality,and it is essential to understand genetic effect of isoforms of starch branching enzyme(SBE) on starch biosynthesis for wheat quality improvement.The starch contents were assessed with 90 wheat cultivars,including 83 domestic hexaploid wheat from different province of China and 7 exotic ones.The genotypes of SBE were also investigated using native polyacrylamide gel electrophoresis(Native-PAGE).The result indicated that there were two loci,SBEⅠ and SBEⅡ,of SBE.SBEⅠ menifested diverse polymorphism with the allele loci of A,B,Dⅰ and Dⅱ.SBEⅡ only exhibited one locus,ie,SBEⅡa.Among all 90 wheat cultivars,seven genotypes were observed based on four allele loci of SBEⅠ.In order to explore the relationship between the genotype and amylopectin content,genetic effects of different genotype on amylopectin content and multiple comparison analysis were conducted.It showed that the amylopectin content of genotypes containing A locus(A DⅰDⅱ and ADⅰB) were relatively higher,which there was significant differences at 0.05 level compared to that of DⅰB and DⅰDⅱ,especially to Dⅰ.It was concluded that there was different genetic effects for different genotype of SBE on amylopectin content.
