Rice breeding for blast resistance is the optimal strategy to effectively manage the disease in rice production worldwide. The Vietnamese landrace “Te Tep” has become a source of breeding material providing target genes for broad-spectrum and sustainable blast resistance. Te Tep is an indica subspecies with a genome carrying many resistance genes and gene clusters to blast fungus. The inclucled genes could be cited as followed: Pi-tp gene on chromosome 1; Pi-54 and Pi-kh on chromosome 11; Pi-2t on chromosome 2; Pita, Pita2, Pi-67 on chromosome 12, near the centromere; and especially the gene cluster encoding the protein NLR-LRR (nucleotide-binding site leucine-rich repeat). All of these have formed a rice genome dealing with many rare genetic material (donors) for rice breeding program of high-yielding varieties with broad-spectrum and sustainable blast resistance.
