The genetic diversity of blast rice resistance of the rice commercial and local resource cultivars in Jiangxi Province were studied using resistance gene analogue (RGA) based on resistance gene conserved sequences. The RGA analysis for 23 cultivars was proceeded by the PCR amplification using the primers XLRR for/XLRR rev designed based on the resistance gene Xa21 for Xanthomonas oryzae pv. oryzae. The results showed that rice cultivars were genetically highly diverse.
