transgenic pollution from wheat
The review below indicates that contrary to corporate and government
propaganda the spread and pollution of surrounding crops by transgenic
wheat is a likely scenario. In a sane world transgenic wheat would
neither be field tested nor released until the limits of transgene
pollution were established. However, if the agencies like the Canadian
food inspection agency are conspiring with corporations to pollute the
entire wheat crop to facilitate rapid employment of the transgenic
varieties their action is not so much insane as it is evil.

REVIEW & INTERPRETATION
Intraspecific Gene Flow in Bread Wheat as Affected by Reproductive
Biology and Pollination Ecology of Wheat Flowers
J. G. Waines* and S. G. Hegde
Gene flow is transfer of genetic information between populations of the
same or different species. Gene flow in bread wheat (Triticum aestivum
L.) occurs via pollen or seed dispersal. Under normal conditions, gene
flow between wheat cultivars is negligible due to selfing of flowers.
Factors such as reproductive biology and environmental conditions at
vegetative and reproductive stages bring variation in the extent of gene
flow. Cultivars with open florets during pollination may have increased
gene flow. High or low humidity or temperature during anthesis may
decrease gene flow. Although pollen movement has been observed 1000 m
from the source, substantial outcrossing beyond 30 m was not observed.
Rigorous and systematic gene flow studies in wheat are absent from the
scientific literature. Gene flow data could establish an appropriate
isolation distance between cultivars and genetically modified (GM)
plants or hybrids.
