title: [Genetic variation of Citrus calli revealed by the ploidy analyser].
abstract: The cell DNA content of forty-eight Citrus calli of different genotype were measured by using the Ploidy Analyser. The results showed that 93.8% out of forty-eight Citrus calli had double DNA content except that Ruby. Weizhang and Kinnow had little varied cells and did not show second peak. Moreover, Pineapple, Meiwa kumquat, Changsha, Russ navel, Guoqing No. 4 and Carter had DNA varied cells including triploids and aneuploids based on the DPAC software analyse. Among the forty-eight Citrus calli, Pineapple had the highest of the DNA varied cells, which was up to 18.57%, Anliucheng had the lowest, 4.07%. There existed significant difference in the variation among genotypes by Duncan Analyse. At the same subcultured medium and at the same subcultured period, the effect of cultural duration on the variation of calli was not significant.
