“…A further shift in the P . infestans population on potato in Thailand was shown by Petchaboon et al (2014), who studied 80 isolates of P . infestans collected in 2000–2002, 27 from potato and 53 from tomato, all of which were A1 mating type.…”

“…A new RFLP genotype with A2 mating type and Ia mtDNA haplotype from Thailand designated TH-1 was characterized by Gotoh et al (2005), who reported that this genotype also occurred in other Asian countries including Nepal and southwestern China. A further shift in the P. infestans population on potato in Thailand was shown by Petchaboon et al (2014), who studied 80 isolates of P. infestans collected in 2000-2002, 27 from potato and 53 from tomato, all of which were A1 mating type. All their isolates from tomato, with one exception, belonged to the US-1 clonal lineage, in agreement with Nishimura et al (1999) and Gotoh et al (2005).…”

“…All their isolates from tomato, with one exception, belonged to the US‐1 clonal lineage, in agreement with Nishimura et al (1999) and Gotoh et al (2005). However, Petchaboon et al (2014) reported that, with two exceptions, their isolates from potato were mtDNA IIa and had RG57 patterns that matched European lineages. Their predominant potato lineage, which they assigned to RF006 (Day et al, 2004), is identical to EU_8_A1, consistent with data from 2009 confirming the presence of EU_8_A1 in samples collected from potato in Thailand (R. de Boer and A.T. Slater, Agriculture Victoria, Australia, 2020, personal communication).…”

The dynamics of Phytophthora infestans populations in the major potato‐growing regions of Asia – A review

et al. 2021

Asia is now the largest potato‐producing region of the world and late blight, caused by Phytophthora infestans, is the most important pathogen limiting production. This review documents, in both the historical and the current context, the population structure of P. infestans in the major areas of potato production in Asia. Information from diverse sources regarding the stated or inferred clonal pathogen lineages present, population changes, and possible migration routes of the pathogen into the countries of this region have been reviewed to aid researchers and those involved in managing late blight in Asia. The single most important factor for population change and resultant epidemics in this region has been found to be migration of pathogen genotypes from Europe and the Americas. Reducing the impact of such migration in the future will necessitate putting in place improved phytosanitary measures. To achieve this, data sharing using global networks such as AsiaBlight and EuroBlight is imperative.

“…regions of tomato and potato production where late blight disease has been studied; regions of tomato and potato production where late blight disease has not been studied. Six years later, in 2000, the populations of P. infestans in tomatoes were characterized by Petchaboon et al [11]. Late blight isolates were collected in Mae-rim during 2000-2002 from the same areas as the Nishimura collection in 1994.…”

Late blight, caused by the oomycete Phytophthora infestans, is one of the most important diseases affecting tomato and potato production worldwide. In Thailand, the disease is widespread in the north and northeast, especially in the Chiang-Mai and Tak provinces. The mating type, metalaxyl sensitivity, mitochondrial DNA (mtDNA) haplotype, RG57 fingerprinting, and microsatellite were used to characterize the P. infestans populations. The study revealed that the P. infestans of tomato isolates in Thailand are of the same lineage as those from 1994 until 2002. The clonal lineages that were found in the potato populations have changed since 1994. The changes in P. infestans isolates in the potato populations have likely been the result of the import of seed potatoes to Thailand. Furthermore, the P. infestans populations in potatoes show resistance to metalaxyl, whereas those from tomato isolates show sensitivity to fungicides. The reasons for the different responses can be attributed to (i) the use of metalaxyl, (ii) the host preferences of P. infestans, and (iii) the migration of new genotypes from infected potato seeds.

“…Recently, a European lineage EU-13 A2 has spread in China and has become the dominant lineage within few years (Li et al, 2013b;Tian et al, 2015b). In Thailand, the population structure analysis showed the dominance of US-1 and the isolates showed sensitivity to metalaxyl (Petchaboon et al, 2014). From Pakistan, both mating types of P. infestans A1 and A2 have been reported.…”

Phytophthora infestans is a destructive pathogen that causes late blight of potato worldwide. Several sexually and asexually reproducing lineages of the pathogen have been identified and new lineages are more virulent as compared to their parental lineages. A new highly aggressive clonal lineage EU13_A2 has spread into potato fields of Europe, Africa and Asia in place of the older lineages. In North America, 24 clonal lineages US1to US24 have been identified. Despite of sexual reproduction, the overall population of P. infestans in potato and tomato fields is dominated by asexual lineages. Breeding has been done to transfer 'R' genes into commercial potato cultivars through classical breeding and by pyramiding of genes. Defender is the only potato cultivar that has foliar and tuber resistance to late blight. Genetically modified potato with RB gene from Solanum bulbocastanum has been developed but it lacks tuber resistance to disease. This review discusses population structure of P. infestans worldwide and breeding efforts to produce late blight resistant potato.
