The genetic variation and intraspecific relationship between 39 cultivars of Lactrca sativa var. capitata was investigated using RAPD (randomly amplified polymorphic DNA) analysis. The 12 primers out of 50 random primers were amplified for all plants tested. The 55 (78.6%) among 70 bands derived from 12 primers showed polymorphism, and 4.6 bands per primer was pbserved. Numbers of bands per primer was found to be 3 to 11, and aberage number was 5.8. The phenograms for 39 analyzed cultivars by RAPD markers did not match well with those of the result of coefficient value ranging from 0.61 to 0.98. The RAPD markers are not useful to evaluate the intraspecific variations in Lactuca sativa var. capitata cultivars.
