Over a year has passed since commercialization of Roundup Ready (RR) hard red spring wheat in the U.S. and Canada was put on indefinite hold over concerns about market acceptance in the two countries and in major wheat importing countries. The continued expansion in production of biotech crops indicates that biotech wheat may have a brighter future in the years ahead.
Biotechnology continues to grow in acceptance as a valuable production tool to increase output, تكاليف أقل, reduce pesticide use and enhance consumer value. Last year Brazil established a government regulatory structure for biotech crops. Biotech white corn for human consumption is increasingly accepted by small growers in South Africa. India has approved additional varieties of Bt cotton for more areas of the country. China has completed extensive farmer field trials on Bt rice. Australia has had broad adoption of Bt cotton and is having a wide ranging debate on production of other biotech crops. The Philippines has approved additional varieties of biotech corn. The EU and Japan have approved additional corn varieties for import for feed and food use. Over one billion acres of biotech crops have been planted since commercialization began in 1996.
The issue of biotech wheat is much wider than just herbicide tolerance. Syngenta is working on a biotech fusarium head blight (FHB) resistant wheat. FHB is considered to be the number one problem in yield and quality for small grains. The fungus can be controlled with pesticides, but the spray window is fairly narrow for the best control.
Less talked about is drought tolerant biotech wheat. Drought tolerance is an issue for the richest soils in the U.S. and Argentina and the poorest soils in Africa. Wheat has been characterized as a “desert weed” because of its limited need for water, but it still needs substantial water at critical seed formation and development stages.
Biotech wheat also holds promise for consumer traits. Protein quality, nutrient content, reduced allergens, freshness and shelf-life of products are all consumer issues at various levels of research. Without acceptance of biotech production practices, consumer traits would have to carry the whole weight of gaining regulatory and consumer acceptance of biotech wheat.
Wheat has to compete with other crops for the use of farmland. Some analysts consider RR wheat and FHB resistant wheat as the first major production technology breakthroughs for wheat since semi-dwarf varieties in the early 1970s. The competition for farmland can be seen in the shift in crop acreage over the past 10 years in North Dakota, a major growing area for hard red spring wheat. قبل 1996 government farm program payments were tied to historical planting patterns for crops. على 1996 farm bill allowed farmers to respond more to market prices and production costs.
في 1995 North Dakota farmers planted 11.3 مليون فدان من القمح. قبل 2005 wheat plantings fell to 8.9 مليون فدان. فول الصويا, canola and corn which benefit from biotechnology have increased acreage in North Dakota from 1995 إلى 2005. Soybean acres increased from 0.7 مليون فدان إلى 3.0 مليون دولار, canola from 0.2 مليون فدان إلى 1.0 مليون فدان, and corn for grain from 0.7 مليون فدان إلى 1.5 مليون فدان.
In a June 2005 report William Wilson and others from North Dakota State University estimated that hard red spring wheat yields would increase by 11-14 percent with the use of Roundup Ready Wheat (RRW). They noted this is similar to yield increases with the adoption of biotech corn. Estimates of cost savings range from $8.30 إلى $11.57 per acre for adopters of RRW. Nonadopters are expected to save about $2.28 per acre as other herbicide treatments are expected to have lower prices to meet the new competition.
من أجل 2000 إلى 2004 North Dakota spring wheat yields averaged 36 bushels per acre and market prices averaged $3.22 كل بوشل. An increase of 11 percent in yield would increase yields by 4 bushels per acre and gross income by almost $13 للدونم الواحد. The combined increase in yield and reduction in cost would be over $20 للدونم الواحد. Total gross income per acre averaged $115 من أجل 2000-2004.
الولايات المتحدة. and Canadian wheat growers also face the possibility that China may jump ahead of them in releasing a biotech wheat. Most of the attention in China is now focused on a decision to allow commercial biotech rice production. Once that decision is made, China would likely also allow production of other biotech food crops, بما في ذلك القمح. If China commits to commercialization of biotech wheat, researchers in other countries that are major wheat producers are likely to step up commercialization efforts.
While countries like Japan and the EU are rich enough to have the luxury of rejecting biotech wheat, other price sensitive buyers are much more likely to be accepting if some of the lower costs of production are reflected in lower market prices. The Wilson report cited earlier suggested that the market price difference for biotech wheat may be $0.15-0.25 كل بوشل. Spring wheat is considered a premium wheat because of its higher protein content. The ability to get a premium product for less than a premium price could cause some buyers to accept biotech wheat.
الولايات المتحدة. and Canadian wheat producers cannot idly set by as the biotech revolution continues to march around the world. They will have to address real market issues and find solutions that work for producers and consumers.
