Herbicide Resistant Rice Development For European Continental Project

Resim 1 Açıklama

New GMO-free resistance pathway to control weedy rice

Rice is one of the most widely grown cereal crops in the world, cultivated in more than 120 countries, mainly in Asia and Africa. In the European region, the rice crop is grown in some 13 countries on about 625 000 hectares of land. With global rice demand on the rise, there is pressure to find new ways to protect against weedy rice, which poses a major threat to sustainable rice production worldwide. The evolution of herbicide-resistant weeds requires new methods for weed control. The EU-funded HerbaRice project is developing a non-GMO, herbicide-resistant new base rice for European countries. It can be used to control weed and weedy rice that has gained resistance against conventional rice herbicides in the fields.

Objective

 Global rice production, so far, has been able to meet population demands. Rice production is considerable exposed to the environment and natural detrimental affect especially weed and weedy rice problems. Present herbicides are often suffered to kill weed and weedy rice that allows for more chemical usage and non-sustainable rice production system. Weed and weedy rice are a great problem because of resistancy and cultivation system such as direct seeded area, especially in Europe. In order to control the problem, Clearfield and Provisia technology developed in the United States. But some weed species or weed varieties are getting resistant to Clearfield rice in Europe in the last years. Thus, new alternative tools are needed for weed control.
 The main aim of the project is develop to non-GMO herbicide resistant new base rice for European countries. Herbicide resistant new base rice might be utilized control weed and weedy rice where gained resistance against to conventional rice herbicides in the fields. Project will investigate to develop non-GMO resistancy with Clethodim (Cyclohexanedione-Dim Group) herbicide resistance for rice. For this reason first objective is execute a mutation on rice seeds, second is develop to low and high resistancy on rice plant, the next objective is determination of mutation point on mutagen resistant rice. Last objective is investigated to deterioration of currently utilized herbicide resistancy system on especially the basis of IMI resistant red rice at incoming phase.  
 The new resistancy system might be available to use when Clearfield and Provisia technology break down because of gene flow and misusage. The HerbaRice project will give new insights on weed and weedy rice problem on rice fields, providing new tools for herbicide resistancy producing safer and sustainable food production.

State of Art

 Researches on rice for weed problem are worked hard nowadays. The result of the researches wasa chieved two main types resistancy which GMO and Non-GMO resistancy. GMO resistancy is including  glyphosate (EPSPS inhibitor) and glufosinate (GA inhibitor) resistance rice but this typerice could not be cultivated in EU because of GMO legislative regulations. Non-GMO resistancy is including Clearfield (ALS, acetolactatesynthaseInhibitor) and Provisia (ACCaseinhibitor) technology. Clearfield technology is using more than a decade but some rice fields getting suffer from IMI (imidazolinone) resistant weed and weed yrice. It might be this technology could not be work next ten years because of gene flow and misusage.  And Provisia technology was developed in 2018 and it use only USA where developed place. For this reason,  new alternative herbicide sareneeded for weed and weedy rice control. Mutation point for resistant rice has not patented for Dim (Cyclohexanedione) chemistry yet. The state of art for the project is to develop Non-GMO resistancy with clethodim herbicide resistance for rice.
