“…Earlier screening for virus resistance, the line 'IHR 2451' as jackpot genotype showed resistance to two major viruses (Naresh et al 2016). Identification of RGAs and their use in identification of markers for disease resistance for marker assisted selection is an ideal approach (Yang et al 2013;An and Yang 2014;Mutlu et al 2008).…”

“…In the present study, one such jackpot genotype viz., IHR 2451 has been identified as a source of resistance to Cucumber mosaic cucumovirus (CMV) and Chilli veinal mottle potyvirus (ChiVMV) (Naresh et al 2016), was also reported to be resistant to TMV (Tobacco Mosaic Virus) and other Leaf curl viruses (Singh and Thakur 1979). So this 'Jackpot' genotype 'IHR 2451' was used to isolate RGAs using PCR based approach.…”

Viruses are serious threat to chilli crop production worldwide. Resistance screening against several viruses resulted in identifying a multiple virus resistant genotype 'IHR 2451'. Degenerate primers based on the conserved regions between P-Loop and GLPL of Resistance genes (R-genes) were used to amplify nucleotide binding sites (NBS)-encoding regions from genotype 'IHR 2451'. Alignment of deduced amino acid sequences and phylogenetic analyses of isolated sequences distinguished into two groups representing toll interleukin-1 receptor (TIR) and non-TIR, and different families within the group confirming the hypotheses that dicots have both the types of NBS-LRR genes. The alignment of deduced amino acid sequences revealed conservation of subdomains P-loop, RNBS-A, kinase2, RNBS-B, and GLPL. The distinctive five RGAs showing specific conserved motifs were subjected to BLASTp and indicated high homology at deduced amino acid level with R genes identified such as Pvr9 gene for potyvirus resistance, putative late blight resistance protein homolog R1B-23 and other disease resistance genes suggesting high correlation with resistance to different pathogens. These pepper RGAs could be regarded as candidate sequences of resistant genes for marker development.

“… Min et al (2014) reported three accessions, “ I7339 ,” “ ICPN-18-8 ,” and “ Daedlbo ,” with resistance to CMV P 1 . More recently, several accessions with resistance to CMV were identified from 50 pepper resources ( Naresh et al, 2016 ). Rahman et al (2016) identified two C. annuum genotypes, CA23 (Noakhali) and CA12 (Comilla-2) possess genes conferring resistance and moderate resistance phenotype to CMV, respectively.…”

“…The application of a mixed inheritance model revealed two additive-dominant major genes with additive-dominant polygenic traits in the CMV-resistance source “BJ0747-1-3-1-1” ( Yao et al, 2013 ). Polygenic recessive resistance has been reported in “IHR 2451” and “IHR 4503” by Naresh et al (2016) . Single-gene control of resistance against CMV has also been reported.…”

Cucumber mosaic virus (CMV) is a prevalent virus affecting the quality and yield of pepper, resulting in yield losses of greater than 80% during severe local epidemics. Cultural practices and the heavy use of agrochemicals are the most common control measures for CMV. Sources of resistance provide a practical reference and a basis for breeding for CMV resistance. Genetic factors underlying CMV resistance have been studied and advanced breeding lines and cultivars with improved resistance have been developed by traditional breeding methods. Additionally, QTLs or genes for CMV resistance have been identified and can be utilized for marker-assisted resistance breeding. This review focuses on status and prospect of CMV against different virus strains, host resistance, and its applied genetics. With the advent of novel technologies, more useful markers and precise approaches can facilitate the progress for improving CMV resistance in Capsicum.

“…RAPD marker converted to SCAR (SCUBC191423) linked to Pvr4 gene helps in MAS (Arnedo-Andres et al, 2002). Chilli veinal mottle virus (ChiVMV) resistance in 'IHR 2451' was monogenic recessive and K5-HD6 a RGAP marker which co-segregated with ChiVMV resistance which helps in the marker assisted selection (Naresh et al, 2016). QTL associated with some important trait is given in Table 1.…”
