Inheritance and linkage relationships of polymorphic isozymes in Lilium longiflorum were demonstrated. Eleven enzyme systems were stably resolved by starch gel electrophoresis. Five of them exhibited polymorphisms, and eight loci with 20 alleles were determined by segregation patterns of offspring obtained from six artificial crosses with horticultural cultivars and wild strains. Contingency chi-square analyses of independent assortment for 64 pairs of loci indicated two linked pairs, Aat-2/6Pgd-2 (recombination fraction, R=0.34± 0.07) and Fest-2/6Pgd-1 (R=0.29±0.08). Resolved enzyme systems and allozymes could be very efficient for estimating genetic diversity among natural populations in L. longiflorum.
