Abstract
The pattern of gene flow by pollen in a line of 18 trees in a commercial almond orchard was investigated.
The orchard planning followed a 1:1 design with a row of Nonpareil cultivar alternating with rows of pollinizers including Carmel, Fritz, Keane, Peerless and Price; the rows bearing at right angles to the line of 18 trees studied.
Results showed that gene flow by pollen is highly leptokurtic, with the highest flow coming from the nearest neighbor tree.
An exception was the pollen gene flow between Fritz and Keane trees, which was higher than expected for trees not being nearest neighbors.
Pollen returning to a honey bee hive had 80–90% of the loads with only one cultivar, suggesting a high degree of fidelity.
