Mk. Wanous et Jp. Gustafson, A GENETIC-MAP OF RYE CHROMOSOME 1R INTEGRATING RFLP AND CYTOGENETIC LOCI, Theoretical and Applied Genetics, 91(5), 1995, pp. 720-726
A genetic map of rye, Secale cereale L., chromosome 1R covering 247 cM
was constructed utilizing 27 RFLP and four C-band markers, including
terminal C-bands. Genetic mapping of C-bands and the centromere, and i
n situ hybridization of three RFLP clones, allowed for the integration
of the genetic and cytological maps. Eight contact points between the
genetic and cytological maps revealed variation in the recombination
distance to cytological distance ratio ranging between 0.25 and 1.95,
a 7.8-fold difference. Recombination was found to be highest in the sa
tellite region of 1RS and lowest in the most distal region of 1RL.
