AI Technical Summary
The lack of reference sugarcane genome information in existing technologies has increased the difficulty of sugarcane variety selection and breeding, especially the lack of effective molecular markers for controlling sucrose content, making it difficult to quickly and accurately cultivate high-sugar sugarcane varieties.
A SNP marker related to sugarcane sugar content was developed, located at position 47469846bp on sugarcane chromosome 3. Breeding was carried out by detecting sugarcane samples with AA or AG genotype at this position. Direct sequencing, specific probe hybridization, specific primer extension or PCR were used for detection. Detection methods and kits were provided for screening sugarcane plants with high sugar content and improved sugarcane varieties.
It realizes the precise detection and efficient screening of the sucrose content of sugarcane, improves the accuracy and efficiency of sugarcane breeding, can significantly increase the sucrose content of sugarcane, and promotes the selection and breeding of high-sugar sugarcane varieties.
