Abstract:
QTL analysis for resistance to cucumber mosaic virus (CMV) was performed in an intraspecific Capsicum annuum population. A total of 180 F3 families were derived from a cross between the susceptible bell-type cultivar Maor and the resistant small-fruited Indian line Perennial and inoculated with CMV in three experiments carried out in the USA and Israel using two virus isolates. Mostly RFLP and AFLP markers were used to construct the genetic map, and interval analysis was used for QTL detection. Four QTL were significantly associated with resistance to CMV. Two digenic interactions involving markers with and without an individual effect on CMV resistance were also detected. The QTL controlling the largest percentage (16-33%) of the observed phenotypic variation (cmv11.1) was detected in all three experiments and was also involved in one of the digenic interactions. This QTL is linked to the L locus that confers resistance to tobacco mosaic virus (TMV), confirming earlier anecdotal observations of an association between resistance to CMV and susceptibility to TMV in Perennial. An advanced backcross breeding line from an unrelated population, 3990, selected for resistance to CMV was analyzed for markers covering the genome, allowing the identification of genomic regions introgressed from Perennial. Four of these introgressions included regions associated with QTL for CMV resistance. Markers in two genomic regions that were identified as linked to QTL for CMV resistance were also linked to QTL for fruit weight, confirming additional breeding observations of an association between resistance to CMV originating from Perennial and small fruit weight.
