Inheritance and linkage of allozymes in Pinus armandii FRANCH.

Ten enzyme systems (ADH, FDH, FLE, LAP,MDH, MEN, 6PGD, PGI, PGM, SOD) codin g for 20 loci were investigated in Pinus armandii. MENDELian inheritance wa s confirmed for allozymes at 12 loci by testing the fit of band-pattern seg regation in macrogametophytes from heterozygous trees to the expected 1:1 r atio. Linkage relationships were examined for 41 pairs of allozyme loci. Fo ur pairs of loci appear to be linked: Pgi2-Sod2 with a recombination freque ncy (R) = 0.11; Adh2-Men2, with R = 0.13; Men2-Sod2, with R = 0.18, and Adh 2-Sod2, with R = 0.29.
