Osnovne informacije
The cultivation of GMHT oilseed rape is likely to occur in Ireland in the near future. In response, Teagasc initiated a 3 year project designed to (ja) study the potential and consequence of HT trait transfer into wild Brassica populations, (ii) establish an integrated weed management strategy to ensure the efficacy of glyphosate is maintained for the tillage sector and (III) conduct both temporal and spatial modelling to determine the potential spread of the GM trait into non-GM crops across the landscape.

Razlozi za Blok / Delay
The work was due to start in 2003. Međutim, the licensing process and authorisation required to secure a Class B license for 3 years delayed the project for over 12 mjeseci. To ensure that there were no further delays, we acquired imidazolinone (IMI) HT oilseed rape from a supplier in Australia. IMI HT oilseed rape
confers an equivalent phenotype to glyphosate tolerant oilseed rape; both are herbicide resistant. Još, because IMI oilseed rape was generated through EMS mutagenesis as opposed to GM techniques it is exempt from licensing under EC 2001/18. As a result we were able to conduct large-scale field trials over 3 years in Ireland using HT oilseed rape. As expected its trait introgressed into native flora populations and as expected the management of the crop requires particular attention, in order to ensure the control of volunteers.
The frustrating point about this research was that we were unable to grow GM HT oilseed rape but yet there was no restriction to growing IMI HT oilseed rape, which performs in the same manner and spreads its genes through essentially the same mechanisms. It was a classic example of how current EU regulations license the process and not the product and remain oblivious to the fact that you can generate the same crop phenotype from different methods. Dakle, dok će njihov utjecaj na okoliš biti isti, jedan je strogo zakonski propisan dok je drugi slobodno dostupan za uzgoj.
Neminovan Prednosti
Teagasc je državna istraživačka agencija zadužena za rješavanje pitanja od javnog značaja. GM je jedno od tih pitanja, ali ipak je mogućnost istraživanja i istraživanja ograničena zakonom, koja ne poznaje principe biologije. Rezultati ovog istraživanja mogu se objaviti, a započeto je u 2005. Izostala korist je da tek trebamo proučavati GMHT uljanu repicu u Irskoj.
Troškovi istraživanja
Troškovi istraživanja bili su jednaki onima koji su bili predviđeni u proračunu za GMHT uljanu repicu. Najveća cijena bila je to što smo izgubili godinu dana.
