“…Since none was found to be located on chromosome 3, 11 or 12, at least three GLH‐resistance QTLs in this study should be new GLH‐resistance loci. The relationship between the QTL on chromosome 5 in this study and Glh6 (Tomar and Tomar, 1987) needs to be investigated further. QTLs were not detected in other chromosome regions, like Glh3 on chromosome 10 (Sidhu and Khush, 1979).…”

“…The main finding of this study is identification of four loci for GLH resistance carried by the resistant parent ARC10313. Of the nine GLH‐resistance genes reported previously (Kinoshita, 1995; Tomar and Tomar, 1987; Sebastian et al, 1996), the chromosomal location of only two genes, Glh3 on chromosome 10 (Sidhu and Khush, 1979) and Glh6 on chromosome 5 (Tomar and Tomar, 1987) are known. Since none was found to be located on chromosome 3, 11 or 12, at least three GLH‐resistance QTLs in this study should be new GLH‐resistance loci.…”

“…Nine GLH‐resistance genes have been reported (Kinoshita, 1995; Tomar and Tomar, 1987; Sebastian et al, 1996) but the chromosomal locations of only two genes, Glh3 on chromosome 10 (Sidhu and Khush, 1979) and Glh6 on chromosome 5 (Tomar and Tomar, 1987), are known. Marker‐assisted selection (MAS) based on molecular genotypes, such as RFLP (restriction fragment length polymorphism), SSR (simple sequence repeat), and SNP (single nucleic acid polymorphism) holds promise for confirming the selection and accelerating the rate of development of GLH‐resistant crops (Harushima et al, 1998; Temnykh et al, 2000; Nasu et al, 2002).…”

Nephotettix virescens Distant (green leafhopper: GLH) is one of the major insect pests of rice (Oryza sativa L.) in the temperate rice growing region of Asia. The objective of this study was to determine the chromosome locations of some GLH‐resistance genes and conduct genetic analysis of GLH resistance. From a cross between the japonica cultivar Taichung65, which is susceptible to GLH, and indica cultivar ARC10313, which is resistant to GLH, 125 recombinant inbred F10 lines (RIL) were developed. Quantitative trait loci (QTLs) for antibiosis to GLH were detected on chromosomes 3, 5, 11, and 12. The QTL near XNpb292 on chromosome 12 for GLH mortality was from the japonica cultivar, while the other three QTLs on chromosomes 3, 5, and 11 were from the indica cultivar. The percentages of observed phenotypic variance attributable to the major QTLs on chromosomes 3 and 11 were 25.3% and 56.8%, respectively. These two QTLs were close to two green rice leafhopper (GRH, Nephotettix cincticeps Unler) resistance genes, Grh4 and Grh2, respectively. Using NILs (near isogenic lines) of Grh4 and Grh2, we determined that the interaction of these two GRH resistance genes expressed strong resistance to GLH. Four GLH‐resistance QTLs, including two major QTLs linked to XNpb144 on chromosome 3 and G1465 on 11, respectively, were identified in this study, and these two major QTLs were located close to Grh2 and Grh4 It may be possible to pyramid these genes to improve resistance to both GRH and GLH.
