- cMV has caused severe damages in fl?Hf""J ,,,, intbction ,:aused major yieid reduction in Indonesia, Inheritance study on resistance to CMV showcd that resistance 1o CMV was co(rtrolled by at least three recessiYe genes. The objective of this study was to idenrifu i)NA rnarkers linked to CMV resistance gene(s) in hot pepper using bulk segregant analysis (BSA) sh'ategy. Molecular markers were cleveloped by RAPD analysis on the F2 generation generated from a cross between C 102,i and, C frutesscetil as rhe mapping population' DNAgenomeswereisolatedfromseventytworandornlysampledpiantsofasegregatedF2popriition and were amplified with six groups of random primers from Operon Technologies of OpA, OpC, OpE, Opt OpFl and OPM each ofwhich consisted of 20 primers. Result of the experiment obtained 20 CMV resistance specific RAPD markers. These RAPD markers are grouped ^nto two linked groups and one of the nrarkers (OpH5ro) r,r.as shown to be associated with one of the three CMV resistar. ce gerres with the log-lil.:elihood (LOD) vatue of:.6+. The OPH5,* marker linked to a CMV resistance gene with a distance of 8.1 cM, and may be used to assist hot pepper breeding programs lbr CMV resistance.
