Variation in disease severity in the lodgepole pine-western gall rust pathosystem

1990-12-01

Abstract excerpt

The number of western gall rust (Endocronartium harknessii) infections per tree was measured in a lodgepole pine (Pinus contorta) population consisting of 3,215 trees in 20 blocks, established from a single, large seed lot collected and planted near Prince George, B.C. Canada. Average disease incidence in these blocks varied from 0.58 to 6.07 infections per tree. A method is presented that allows the prediction of...
