RETRACTED ARTICLE: Genetic inheritance and identification of a resistance gene analogue polymorphic (RGAP) marker linked to Chilli veinal mottle virus resistance in chilli (Capsicum annuum L.)

Abstract

ABSTRACTChilli veinal mottle virus (ChiVMV) is a most destructive virus, which causes severe yield losses in pepper. Host plant resistance is the only option to tackle this problem. Eleven ChiVMV-resistant lines were selected from an initial screening of chilli pepper germplasm and their resistance was reconfirmed by artificial inoculation. To understand the genetic basis of inheritance and to identify a resistance gene analogue polymorphic (RGAP) marker associated with resistance, the ChiVMV-resistant chilli pepper line ‘IHR 2451’ (Parent 1) was crossed with the ChiVMV-susceptible line ‘IHR 3476’ (Parent 2) to develop six generations. Individual plants from all six generations (35 P1, 50 P1, 30 F1, 200 F2, 44 B1, and 41 B2) were artificially inoculated with ChiVMV (Bengaluru isolate) and the pattern of segregation of susceptibility or resistance was investigated using the chi-square (χ2) test. All F1 progeny plants were susceptible to ChiVMV. The pattern of segregation of resistant and susceptible plants...
