Abstract:

【OBJECTIVE】To elucidate the genetic diversity and phylogenetic relationships of 37 cauliflower cultivars, provide a theoretical basis for cauliflower breeding, 80 random primers were carried out a preliminary screening with 7 among the cauliflower cultivars as amplification template. 【RESULTS】Among which 48 primers gave polymorphism, 25 primers gave monomorphic and 7 primers without amplified bands within the varieties. 【CONCLUSION】Stable, clear and polymorphic bands could be obtained with primers S11, S15, S16, S17, S18 and S65, the percentage of polymorphic bands ranging from 16.7% to 75.0%, and these primers appear to be useful for genetic diversity studies in cauliflower cultivars.
