Genetic control of isoenzymes in Sitka spruce



Genetic control of isoenzymes in Sitka spruce



Journal of Heredity 84(3): 206-211



Allozyme variants were studied for 14 enzyme systems in seed tissues of Sitka spruce (Picea sitchensis (Bong.) Carr.) from 134 seed-orchard clones. A total of 16 enzyme zones was consistently identified, 14 of which were polymorphic loci. Significant departure from the expected 1:1 segregation ratio was observed in six of 24 allelic combinations. No linkage was observed for 16 doubly heterozygous combinations. However, lack of independent segregation between two sets of loci (PGM-1:PGM-2 and PGM-2:6PG-1) was attributed to their apparent linkage.
