“…ADR52 has been noted previously to have strong ontogenic changes in resistance. The BPH25 and BPH26 genes from ADR52 have been previously noted as ineffective in the Philippines and Vietnam [17]; however, according to our results, these genes likely play a role mainly in seedling resistance, with other, unidentified genes expressed in older plants. ARC6650 has been previously noted for its resistance to S. furcifera (Table S1); therefore it is unsurprising that the variety performed poorly against N. lugens at most centers; however, it remained largely undamaged in SSSTs and MSSTs at CAES and APRRI indicating that it does possess brown planthopper resistance albeit with reduced effectiveness because of current widespread virulence.…”

“…Currently some 85 genes for resistance to planthoppers and leafhoppers have been identified from rice and its wild relatives [7,14,17]. These genes continue to form a basis for rice resistance breeding programs in Asia; however, they are subject to planthopper and leafhopper adaptation.…”

“…These genes continue to form a basis for rice resistance breeding programs in Asia; however, they are subject to planthopper and leafhopper adaptation. In recent years, virulent planthopper and leafhopper populations have been noted throughout Asia and these have rendered many major resistance genes ineffective [11,17,35,36]. For example, Horgan et al [11] indicated that the Bph1, bph2, bph5, bph7, bph8, Bph9, Bph10 and Bph18 genes are currently ineffective against planthopper populations in many parts of Asia.…”

“…Combining genes in pyramided lines for deployment in virulence hotspots such as the Punjab and Vietnam requires particular caution. For example, combining any of the genes that are currently ineffective in these regions together into pyramided lines will likely not significantly improve resistance strength or durability [17], and combining an ineffective gene together with a second, apparently effective gene may not bestow any durability advantages to the line compared to monogenic lines with the single effective gene [47]. Breeders might select resistance genes for pyramiding combinations based on the lineages of the gene donors.…”

This study examines aspects of virulence to resistant rice varieties among planthoppers and leafhoppers. Using a series of resistant varieties, brown planthopper, Nilaparvata lugens, virulence was assessed in seedlings and early-tillering plants at seven research centers in South and East Asia. Virulence of the whitebacked planthopper, Sogatella furcifera, in Taiwan and the Philippines was also assessed. Phylogenetic analysis of the varieties using single-nucleotide polymorphisms (SNPs) indicated a clade of highly resistant varieties from South Asia with two further South Asian clades of moderate resistance. Greenhouse bioassays indicated that planthoppers can develop virulence against multiple resistance genes including genes introgressed from wild rice species. Nilaparvata lugens populations from Punjab (India) and the Mekong Delta (Vietnam) were highly virulent to a range of key resistance donors irrespective of variety origin. Sogatella furcifera populations were less virulent to donors than N. lugens; however, several genes for resistance to S. furcifera are now ineffective in East Asia. A clade of International Rice Research Institute (IRRI)-bred varieties and breeding lines, without identified leafhopper-resistance genes, were highly resistant to the green leafhopper, Nephotettix virescens. Routine phenotyping during breeding programs likely maintains high levels of

“…Since the 1980s, no other genes have been widely deployed in modern rice varieties. Nevertheless, it is apparent that planthopper populations have increased in virulence even against genes that have never been widely deployed (i.e., bph8, Bph9, BPH25, BPH26: Myint et al, 2009;Srinivasan et al, 2015). Furthermore, it is clear that planthopper populations from different regions (including different countries and different districts within countries (Verma et al, 1979;Jairin et al, 2007a) differ in their responses to rice varieties with the same resistance genes.…”

This study examines the utility of resistant varieties and their associated resistance genes against brown planthopper, Nilaparvata lugens (Stål), populations from South and South East Asia. A collection of 39 rice accessions that included resistant, tolerant and susceptible varieties and breeding lines were examined for performance against populations of N. lugens from India (4), Bangladesh (1), Myanmar (1), Vietnam (1), Indonesia (1), China (1), Taiwan (1), and the Philippines (2). Planthopper virulence varied between regions; however only 6 varieties were generally less damaged than the susceptible check Taichung Native 1 (TN1) among ≥50% of the test populations. Each of these 6 varieties contained multiple resistance genes. One further variety, also with multiple resistance genes, and a modern cultivar (possibly with the Bph3 gene) were moderately effective against the South Asian populations, whereas a traditional variety with the Bph6 gene was effective against South East Asian populations. Bph1, bph2, bph5, bph7, bph8, Bph9, Bph10 and Bph18 were ineffective against most planthopper populations. Bph20, Bph21, and Bph17 have potential to be used in resistance breeding in both South and South East Asia, whereas BPH25 and BPH26 have potential for use in South Asia. The results indicate that only a few of the currently available resistance genes will be effective in monogenic rice lines; but that pyramiding of two or more genes with strong to weak resistance could improve resistance strength and durability as apparent with the most resistant, traditional varieties. Strategies to avoid planthopper adaptation to resistant rice varieties are discussed.
