Inheritance and linkage of isozymes in white spruce (<i>Picea glauca</i>)

Abstract

Variation patterns for 26 loci of white spruce (Picea glauca (Moench) Voss) from 16 enzyme systems were studied using haploid megagametophyte tissue. Inheritance models for 17 polymorphic loci were formulated and tested for deviations from Mendelian segregation. Linkage analyses were conducted for 12 of the polymorphic loci in pairwise comparisons. Significant joint segregation was found for three pairs of loci: Pgi-2 with Aat-1, Gdh with Idh, and one of three families tested with Pgi-2 and 6pg-2,3.
