New Success Shows Way for NZ Research
New Zealand must re-focus its scientific programmes around non-GE plant and animal research to gain advances that will
appeal to consumers, farmers and which are environmentally safe.
Overseas scientists are moving away from genetically engineered research and into marker assisted selection (MAS) and
gene pyramiding using conventional crossing of non GE plants with the desired traits.
New Research has just been released on a bean resistant to four different kinds of rust. The beans are conventionally
pollinated crossing two beans with the desired traits then using selection process to find the beans that have been
“gene pyramided”.
The creation of the beans has been all done by natural and selective pollination of plants, avoiding the problems
related to GE techniques. Each time a generation is crossed and its progeny carries the extra genetic desired traits it
is called “gene pyramiding”. Each resulting generation of bean seeds are tested for the presence of the desired gene
using PCR techniques.
Dr Pastor-Corrales, of the Plant Sciences Institute in Beltsville Agricultural Research Center is the scientist who has
worked on this research and writes “None of the beans used in our breeding scheme to produce the great northern
(BelMiNeb-RMR-8, -9, -10, -11, -12, and -13) and pinto (BelDakMi-19, -20, -21, -22, and -23) bean germplasm lines - with
four genes for rust resistance and two genes for resistance to bean common mosaic and bean common mosaic necrosis
poly-viruses - are from genetically modified beans”.
This is the kind of research that New Zealand CRI’s and scientists should be involved in. These beans have been produced
using processes that do not introduce the genetically modified viral or bacterial genes into the DNA of plants and is a
positive use of new diagnostic tools to select for traits.
The process can also be fast; the beans have only taken a few generations to produce the desired traits and are similar
to the seed saving traditions of indigenous peoples over millennia.
We hope that this promising research and outcome will be used to help all farmers and not become restricted by expensive
patents or prohibition on seed-saving that GE seed-producers have tried to force on them.
ERMA must consider such alternative methods of achieving desired resistance in their latest GE brassica (GMF 06001)
assessment.
The continual push for GE is going to become an expensive white elephant that New Zealand will regret because it is
unmarketable, and obscures the great non-GE achievements of our scientists in the agricultural sector.
