Abstract
Supplemental mass pollination (SMP) success in a grafted lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) seed orchard in southern British Columbia was studied by employing four chloroplast DNA (cpDNA) markers to determine fertilization success of 10 pollen parents. SMP was conducted operationally with a bulked pollen mix twice during peak receptivity in the seed orchard. Fertilization success of the 10 SMP parents averaged 16% greater than for wind-pollinated controls in a different section of the orchard. SMP also increased the uniformity of the male contribution in treated seeds.
