Among the planthoppers of rice, the brown planthopper (BPH) is a major threat to rice production and causes significant yield loss annually. Host-plant resistance is an important strategy to reduce the damage caused by BPH and increase rice productivity. Twenty-one major genes for BPH resistance have been identified by using standard evaluation methods developed at the International Rice Research Institute (IRRI) to distinguish resistance or susceptibility of rice genotypes to BPH biotypes/populations. These genes are from diverse genetic resources such as land race cultivars and wild species of Oryza. Of the 21 resistance genes, 18 genes have been localized on specific region of six rice chromosomes using molecular genetic analysis and genomics tools. Some of these resistance genes are clustered together such as Bph1, bph2, Bph9, Bph10, Bph18, and Bph21 on the long arm of chromosome 12; Bph12, Bph15, Bph17 and Bph20 on the short arm of chromosome 4; bph11 and Bph14 on the long arm of chromosome 3 and Bph13(t) and bph19 on the short arm of chromosome 3. Six genes (Bph11, bph11, Bph12, bph12, Bph13 and Bph13) originated from wild Oryza species have either duplicate chromosome locations or wrong nomenclature. The discrepancy should be confirmed by allelism tests. Besides identification of major resistance genes, some quantitative trait loci (QTLs) associated with BPH resistance have also been identified on eight chromosomes. Most of the rice cultivars developed at IRRI possess one or two of the major resistance genes and the variety IR64 has many QTLs and confers strong resistance to BPH. More BPH resistance genes need to be identified from the wealth of gene pool available in the wild species of Oryza. Two BPH resistance genes (Bph14 and Bph18) have been cloned, and a snow drop lectin gene (GNA) has been identified and used in the development of BPH-resistant transgenic plants. Efficient introgression of resistance genes (Bph1, bph2, Bph3, Bph14, Bph15, Bph18, Bph20, and Bph21) into elite rice cultivars by marker-assisted selection together with strategic deployment of these genes can be an important approach to develop stable resistance to BPH and sustain rice production in the tropical and temperate rice growing regions.

“…The Bph3 was assigned to the long arm of chromosome 4 through simple sequence repeat (SSR) and position-specific microsatellite (PSM) analysis (Huang2003), while the bph4 was mapped on the short arm of chromosome 6 through SSR and RFLP analysis (Kawaguchi et al 2001). Khush et al (1985), and Kabir and Khush (1988) identified another three resistance genes, bph5, Bph6 and bph7 from cvs. ARC10550, Swarnalata and T12, respectively.…”

Brown planthopper(BPH) is one of the most serious and destructive insect pests of rice in most rice growing regions of the world. In this study, two major resistance genes against BPH have been identified in an Oryza rufipogon (Griff.) introgression rice line, RBPH54. Inheritance of the BPH resistance in RBPH54 was studied by screening the resistance in parents, F1, F2 and BC1 generations against BPH biotype 2. A population of BC3F2 lines was developed and SSR markers were employed for the gene mapping, and new markers were designed for fine mapping of the resistance genes, while sequence information of BAC/PAC clones was used to construct physical maps of the genes. The results showed that the BPH resistance in RBPH54 was governed by recessive alleles at two loci, tentatively designated as bph20 (t) and bph21(t). The locus bph20(t) was fine mapped to the short arm of chromosome 6 about 2.7 cM to the upper marker RM435 and 2.5 cM to lower marker RM540 and in a 2.5 cM region flanked by two new SSR markers BYL7 and BYL8 which were developed in the present study. The other BPH resistance locus bph21(t) was initially mapped to a region 7.9 cM to upper marker RM222 and 4.0 cM to lower marker RM244 on the short arm of chromosome 10. For physical mapping, the bph20(t)-linked markers were landed on BAC/PAC clones of the reference cv., Nipponbare, released by the International Rice Genome Sequencing Project. The bph20(t) locus was physically defined to an interval of about 75 kb with clone P0514G1. Identification and location of these two genes in the present study have diversified the BPH resistance gene pool, which give benefit to the development of resistant rice cultivars, and the linkage PCR-based SSR markers for the bph20(t) and bph21(t) genes would help realize the application of the genes in rice breeding through marker-assisted selection.

“…The development of a novel BPH resistant cultivar is thought to be the most effective manner to combat this pest. A number of major BPH-resistance genes have been identified from indica rice cultivars (Chen et al 2006, Kabir and Khush 1988, Khush 1979, Khush et al 1985, Nemoto et al 1989, Sun et al 2005. The development of near-isogenic lines (NILs) and pyramided lines (PYLs) carrying one or several resistance genes has been performed (Jairin et al 2009, Sharma et al 2004 and is a most effective manner to facilitate the use of the BPH-resistance genes or of quantitative trait loci (QTLs) for future rice improvement.…”

Development of near-isogenic lines for BPH25(t) and BPH26(t), which confer resistance to the brown planthopper, Nilaparvata lugens (Stål.) in indica rice 'ADR52' Asanori Yara 1) , Cong Nguyen Phi 1,2) , Masaya Matsumura 3) , Atsushi Yoshimura 1) and Hideshi Yasui* 1) The brown planthopper [BPH; Nilaparvata lugens (Stål.)] is one of the most destructive insect pests in Asian rice-growing areas. Two genes conferring resistance to BPH, BPH25(t) and BPH26(t) derived from a BPHresistant indica rice cultivar, Oryza sativa ADR52, have been identified. However, they are linked to genes conferring late heading and hybrid spikelet sterility. To eliminate these unfavorable traits (linkage drag), we generated BC 6 F 1 populations carrying BPH25(t) or BPH26(t) in a BPH-susceptible japonica cultivar, Taichung 65, through marker-assisted selection. We selected three near-isogenic lines (NILs) carrying BPH25(t) without late heading date and one NIL carrying BPH26(t) without spikelet sterility from BC 6 F 2 progeny that showed between 96.3 and 99.8% of the Taichung 65 genetic background through whole-genome survey. In antibiosis testing, the rates of surviving insects and of females with swollen abdomens were lower on the NILs than on Taichung 65, indicating that bph25(t) and Bph26(t) alleles from ADR52 controlled the resistance to BPH. The NILs will serve as useful resources for (1) monitoring BPH virulence and for (2) increasing resistance to BPH.
