Genetic diversity of 32 individual. of P. chinensis in the Chinese coastal.waters of the Huanghai and Bobal.Seas was detected by RAPD technique. Twenty decamer primers of OPI were used for DNA ampl.fication for each individual. The resul.s showed that: Seventeen primers obtained reproducibl. fingerprints, and the bands were cl.ar. Thirty--nine of 106 l.ci detected were pol.morphic, amounting to 36. 8 %. Mean genetic distance was 0. 094 1 0. 020 6; 68 markers (63. 2 % of the total. showed stabl. homogeneity in al. of the 32 individual..

Bl.e straggl.rs are a common observational.fact for the Gal.ctic cl.sters. Singl. Stel.ar Popul.tions (SSPs) are basic to the studies of gal.xy structre and evol.tion. SSPs are mainl. based either on the observation of the integrated properties of star cl.sters, or on the theoretical.understandings of singl. star evol.tion. Both of the two ways of making SSPs suffer from either observational.uncertainties concerning fiel. contaminations or l.ck of good model. for cl.se binary systems. Based on the photometry of the cl.ssical.open cl.ster M67 and the thorough membership survey, we made a col.r-magnitude diagram (CMD) of high membership stars for the cl.ster. We wil. show that by incl.ding the contributions of the bright bl.e straggl.rs that is common to open cl.sters, the integrated properties of the cl.sters are quite different from tranditional.SSP model.. We further concl.de that these bl.e l.ght contributors are very important to SSP model., and may cast new l.ghts on its appl.cations in the studies of gal.xies.
