摘要：

The genetic control of self-incompatibility (SI) was studied in the spring-flowering annual, Linanthus parviflorus (Polemoniceae). Arrays of full-siblings were cross-pollinated in a fulldiallel design and compatibility relationships were assessed by examining for pollen tube growth in styles. Two to four incompatibility types wire observed in each sibship, some types were interincompatible, and reciprocal differences in incompatibility between types were found. The results demonstrated close agreement with expected patterns of incompatibility among full-siblings for sporophytic control of SI with linear dominance. Taken together, these results provide support for sporophytic SI in L. parviflorus. The crossing data presented here are contrasted with results of a previous study indicating gametophytic control of SI in Phlox drummondii, another polemoniaceous species.
