Abstract

Eight hybrid and native pines were planted in 1950 on three locations of the Stanislaus-Tuolumne Experimental Forest. Height, diameter, and survival data were recorded annually. Physical injuries from snow, insects,and animals were surveyed in 1962. After 12 years, the most promising hybrid at 5,200 and 5,400 feet elevation was Jeffrey x (Jeffrey x Coulter). This backcross hybrid showed little damage from insects, snow, or porcupines.
