| Strong drought tolerance is an important objective in breeding new wheat varieties. We compared the drought tolerance of land races and modern varieties of various spring wheat forms. 13C discrimination (CID) indicated how significantly the tested wheat varieties were inclined to drought tolerance. CID is a trait related to stomatal closure and consequently an important component of the tolerance to drought. Samples were grown in České Budĕjovice (CZ), from 2009 to 2012. Twenty-three varieties, comprising einkorn, emmer, spelt, land races and control variety of bread wheat were grown and tested. Results have shown some varieties achieved low CID values (which meant they were more inclined to the drought tolerance). There were emmer and spelt varieties... |

| For the operationalization of the structured, stepwise selection procedure for non-target testing organisms integrated into the new EFSA guidelines for environmental risk assessment of GM plants practicaltools – i.e. ranking matrices – were developed. These tools – some of them are new and some are refinedfrom older ones – were tested using the GM case crop of TC 1507 maize. The selection procedure consists of six steps. The strategy builds on identifying the important ecological functions for the particularcropping system and compiling a species lists according to their ecological functions and presence inthe specific receiving environments. Subsequently, the species numbers are reduced in a systematic,stepwise fashion to a relevant and practical number... |

| This explorative study is an inventory: A first assessment of the problems of accessing organic seed and the contamination of organic cotton seed with genetic modification (GM) in the field. Outcomes of the inventory lead to hypotheses to be tested in further regional workshops. This inventory is an initial step in developing a master plan for safeguarding the availability of organic cotton seed. Approximately 81% of respondents overall, including 90% of organic farmers who responded, are of the opinion that organic cotton seed is difficult to access. In countries where GM cotton is predominant (the USA, India, China and Burkina Faso) close to 90% of respondents feel it is “difficult” to “impossible” to access organic cotton seed. Accessing organic cotton... |

| The report was prepared by the members of the IFOAM-Organics International Working Group on Replacing Cell Fusion Cultivars: Kirsten Arp, Diane Bowen (Chair), Bernd Horneburg, Andre Leu, Rodel Maghirang, John Navazio, Gebhard Rossmanith, Michael Sligh, Yiching Song, and with additional support from Monika Messmer. History of the initiative In 2002 the first IFOAM draft standards were set for organic plant breeding. They stated that only breeding techniques on plant level are compatible for organic principles. This implies that from the process point of view, plant breeding techniques that operate on cell tissue or directly at DNA level violate the integrity of life. Respecting the concept of integrity of life also means that organic agriculture aims to... |
