Data_siring success and seed production_experiment 2

Data on siring success of a focal pollen donor and seed production in Collinsia heterophylla following two-donor crosses involving a focal pollen donor and a standard competing pollen donor on a set of recipient plants. Pollen from the focal pollen donor was applied at floral developmental stage 1 and pollen from the standard competitor was applied at floral developmental stage 2, i.e. one day later. Siring success estimated as proportion seeds sired by the donors using microsatellite markers in up to 20 seeds from four replicate crosses using the same focal and standard pollen donors, and the same recipient. Seed production estimated as number of seeds per capsule as a mean of the four replicate crosses.
