Twenty Russet Burbank seed lots were collected from
four states and one Canadian Province in 1988 and planted in
replicated trails at Powell Butte and Hermiston, Oregon as
part of a two year study to quantify clonal differences in
the cultivar. Samples of each seed lot were concurrently
increased and...
Durum wheat cultivars for North-Eastern Oregon have to be competitive
in terms of their yield potential with soft white winter wheat cultivars and meet
strict quality requirements of the milling industry. Combining the high yield
potential of fall planted durum wheat cultivars which have an acceptable level of
winter hardiness...
The drastic reduction in cattle prices with constantly rising costs
of production emphasizes the value of superior genetic material. Although the costs of progeny testing have risen with other production costs, the positive identification of superior genetic material can only be determined by progeny testing.
Seventy-six heifers and 312 steers...
Forest species classifications are becoming increasingly automated as advances are made in machine learning. The algorithms used to identify tree species range from simple decision trees to intricate neural networks, and often excel in accurately delineating tree species. However, complex algorithms can have high input costs, including the cost of...
The mission of the Greater La Pine Community Wildfire Protection Plan is to protect against loss of life, property and natural resources as the result of wildland fire. This CWPP outlines priorities, strategies and action plans for fuels reduction treatments in the wildland urban interface. It also addresses special areas...

Seedlings were thinned to spacings of 5, 9, 12, 15, and 18 feet and measured periodically. Twenty-seven years after treatment, quadratic mean diameters increased curvilinearity (p < or = 0.05) as spacing increased, but total height did not differ significantly (p < or = 0.05) with spacing. Corresponding basal areas...
The population genetic structure of ponderosa pine (Pinus ponderosa Dougi.) in the Willamette Valley of Oregon was investigated. Cones were collected from native stands of ponderosa pine from the Willamette Valley, eastern Oregon, southwest Oregon and the Puget Sound Basin of Washington. Seeds were subjected to isozyme analysis of 12...
