We used horizontal starch-gel electrophoresis for a genetic analysis of isozymes within one French Cedrus atlantica stand. Eleven to 29 megagametophytes per tree from 186 trees were assayed. Among the 33 enzyme systems tested, 15 correctly resolved and 8 appeared variable in at least one zone of activity: ACP, GOT, IDH, LAP, MDH, MNR, PGI, and SKDH. They were coded by at least 12 polymorphic loci which were described and tested for Mendelian segregation and linkage. Segregation patterns and linkage relationships were variable in the population. We detected homogeneous segregation distortion for loci Idh, Acp-c, and Got-a over the whole set of segregating progeny. We also found segregation distortions in a significant proportion of progeny for loci Got-b, Mdh-c, Pgi-b, and Skdh. The Acp-c and Got-b loci were linked with an overall map distance of 17 cM, but distance varied drastically among progeny. Both segregation distortions and heterogeneity of recombination frequencies indicate the occurrence of a genetic load in this population.
