摘要

In view of the lack of wheat genetic resources with high amylose and high resistant starch contents in the present world,the grain starch components and SGP-1 (SGP-A1,SGP-B1 and SGP-D1) protein composition of 43 black-kernel wheat genetic resources such as Jizi 439 were identified by SDS-PAGE electrophoresis detection.The results showed that 11 materials were lack of SGP-A1,and no materials had SGP-B1 and SGP-D1 deletion.Seven materials were identified to have an amylose content more than 30% of the total starch.A total of 12 materials were selected for the determination of resistant starch content,and five materials were found to have a high resistant starch content.The above results lay a foundation for wheat breeding for high resistant starch content.
