Search for the Brown Planthopper Resistance Gene in Vietnamese Native Rice Varieties

October 10, 2019

Based on the sequence data of 48 native rice varieties conducted by Agricultural Genetics Institute and partners, the researchers have screened and designed Bph26del24 marker to determine Bph26 candidate gene. The Bph26 gene is dominant, was cloned and mapped from indica variety, ADR52 which located on chromosomes 12. Bph26 gene encodes a CC-NB-LRR protein that mediates antibiosis to brown planthopper.The research team identified sixteen native rice varieties that have been carried homozygote candidate gene Bph26.

The results provide a significant genetic sources and molecular marker for breeding programs by using marker assisted selection.
