Abstract
Ten-locus genotypes of endosperm and corresponding embryo of two provenance seed samples of Cunninghamia lanceolata were studied in an attempt to describe predominant characteristics of the reproductive system as realized in the respective populations. The empirical genotypic structures were compared with three types of reference structures: Hardy-Weinberg; multiplicative; and inbreeding. Strong deviations from the hypothesis of random fusion of gametes are obtained. This phenomenon cannot be explained by assuming sexually asymmetrical fertility selection. Results clearly indicate that inbreeding is the most prominent component of the underlying reproductive conditions in both seed samples. Of the additional phenomena involved, the most probable is viability selection. Some general consequences of these results are discussed.
