8243. Auld, D.L. and K.A. Mahler. 1987.. Bridger and Cascade winter rapeseed varieties.. ID Agr. Expt. Sta. CIS 801.
These two varieties are the result of breeding in Idaho since 1976. Bridger is an industrial rapeseed variety, while Cascade is an edible oil type. They yielded only 85 and 70 % respectively of those from Dwarf Essex, the common variety. Oil content averaged over 40 %. The best market potential is for Cascade as a whole seed exported to Japan.

8234. Peterson, C.L., D.L. Auld, and R.A. Korus. 1988. Use of vegetable oil as a fuel in time of emergency.. ID Agr. Expt. Sta. Misc. Series No. 111.
Vegetable oil can be used as a substitute for diesel in emergencies. Engine damage and poor performance are possible consequences, though. Descriptions of the potential problems are included. Transesterification makes the vegetable oils more similar in viscosity to diesel, an important step. The brochure details on-farm ester production with rapeseed oil.

8261. Auld, D.L.. no date. Rapeseed/canola genetics - University of Idaho.. Dept. Plant, Soil,Ent. Sci, Univ. Idaho, Moscow, ID 83843.
Oilseed brassicas currently provide about 15% of the world's edible oil. Products from oilseed brassicas include canola oil, specialty edible oils, industrial polymers, biological fungicides, and clean fuels.

8270. Kephart, K.D. and R.W. Schermerhorn. 1988. Rapeseed production districts in Idaho.. ID Agr. Expt. Sta. CIS 819.
To avoid cross-pollination between industrial and edible oil rapeseeds, Idaho has been divided into six districts. These include edible only, industrial only, edible with restriction, all production prohibited. A map is included.

8279. Kephart, K.D., M.E. Rice, J.P. McCaffrey, and G.A. Murray. 1988. Spring rapeseed culture in Idaho.. ID Agr. Expt. Sta. Bulletin 681.
Rapeseed must be added to the rotation carefully, due to pest problems and herbicide carryover from other crops. The following waiting periods are suggested: none for wheat, barley, oats; 1 yr for buckwheat, corn, field peas, potatoes, fababeans, clovers; 2 yr for alfalfa; 3 yr for sugar beets, mustard, sunflowers, field beans, lentils. Production information for spring rapeseed is included. Yields wil range from 800 to 3000 lb/ac,depending on location and irrigation use.

10049. Kephart, K.D., G.A. Murray and D.L. Auld. . Alternate crops for dryland production systems in Northern Idaho.. ID Agr. Expt. Sta. Contribution 88762, Moscow, ID..
Increased interest in low-cost input management practices and changes to conservation-oriented government programs are providing incentive for farmers to diversify rotation schemes. However, a lack of commercially viable alternate crops has restricted the number of options available to northern Idaho farmers. This paper lists the results of 10 years of alternate crop experiments into four groups. 1) Species offering no production potential are grain sorghum, quinoa, and soybeans. 2) Crops with limited production potential are meadowfoam, mustard and spring rapeseed, lupines, faba beans, flax, and crambe. 3) Commercialized crops with limited production potential are buckwheat, safflower, sunflowers, and chickpeas. 4) Commercialized crops with unlimited production potential are winter peas and winter rapeseed. Tables 2 and 3 summarize planting requirements and erosion control potential for many of these crops.
