Abstract: The study was carried out using a F2 population from a cross between resistant inbred line and susceptible inbred line. Bulked segregant analysis (BSA) was applied to identify RAPD markers linked to the resistance to CMV in squash. 520 random primers and 310 double primers with arbitrary sequences were chosen for RAPD amplification. It was found that the polymorphism between the R-bulk and S-bulk could be detected by 6% and 5% of the primers as well as two RAPD markers S4391400 and S19+S345600 were linked to the resistance gene of K01 with the overcross value of 7.5% and 11.8%, genetic distance of 7.1 and 11.7 cM.

Key words: Squash, CMV, RAPD, Molecular marker
