Tea gray blight caused by Pestalotiopsis longiseta SPEGAZZINI is a severe disease in tea fields in Japan. The resistance of tea plants to the disease was found to be controlled by 2 independent dominant resistance genes Pl1 and Pl2, based on parent-offspring genetic analysis. There were 9 genotypes for resistance to P. longiseta in tea plants. Six genotypes Pl1Pl1Pl2Pl2, Pl1Pl1Pl2pl2, Pl1Pl1pl2pl2, Pl1pl1Pl2Pl2,Pl1pl1Pl2pl2, Pl1pl1pl2pl2 were resistant, 2 genotypes pl1pl1Pl2Pl2, pl1pl1Pl2pl2 were moderately resistant and one genotype pl1pl1pl2pl2 was susceptible. Since the cultivars harboring the Pl1 gene with homozygosity always produced resistant plants to the disease in any cross combinations, they could become very important materials for the breeding of cultivars resistant to the disease.
