Six isozyme systems (ACP, G6PDH, IDH, PGI, PGM and SKDH) codifying for seven polymorphic loci (Acp-2, G6pdh-1, Idh-1, Pgi-2, Pgm-1, Pgm-2 and Skdh-1) were investigated for inheritance and gametic disequilibrium in Cecropia pachystachya Trec. Mendelian inheritance was confirmed for all available loci. Significant segregation deviations from expected ratio 1:1 were detected only in one family from heterozygous tree. Linkage disequilibrium was examined for 21 pairs of allozyme loci. No linkage disequilibrium was detected in the pairs of loci studied. These loci can be used in subsequent mating system, genetic diversity and structure studies of C. pachystachya.
