Investigating Rice Blast Resistance Gene Distribution among Landrace Rice Varieties in Lower Northern Thailand for Improving Rice Cultivars

Figure 3

Visual inspection of the positive PCR product (466 bp long) amplified from Pi9 gene with individual rice DNA template on agarose gel electrophoresis system. Lane M represents the 100-bp DNA ladder (GeneDireX, Taiwan), and other lanes represent the PCR products in PCT germplasms (a), PLK germplasms (b), and STI germplasms (c), respectively. The numbers labelled in each lane indicate rice varieties related to the list in Table 1.
