Commercial fruit production in Norway is located at around latitude 60° north, demanding a careful choice of adapted cultivars. The most comprehensive collection of apple genetic resources in Norway is being kept in the Norwegian Apple Collection (NAC) at the Njøs Fruit and Berry Centre (NJØS). The collection contains around 350 accessions and was recently genotyped with a single nucleotide polymorphism (SNP) array. Curated SNP data were used for the assessment of structure and diversity, pedigree confirmation, and core collection development. In the following SNP analysis, we identified several duplicates and parent-child relationships. Across the geographic regions represented, the collection was equally diverse. Different methods for analyzing population structure were applied. K-means clustering and a Bayesian modeling approach with prior assumptions of the data revealed five subpopulations associated with geographic breeding centers. The collection has a distinct genetic structure and low relatedness among the accessions; hence, two core collections with 100 accessions in each were created. These new core collections will allow breeders and researchers to use the NAC efficiently. The results from this study suggest that several of the accessions in the Norwegian Apple Collection could be of high importance for breeding purposes.

Genetically modified maize DP41149 x MON 890349 x MON 874119 x DAS-40278-9 was developed by crossing to combine four single events: DP4114, MON 89034, MON 87411 and DAS-40278-9. DP4114 express the Cry1F protein to confer protection against certain lepidopteran pests, the Cry34Ab1 and Cry35Ab1 proteins to confer protection against certain coleopteran pests and PAT protein to confer tolerance to glufosinate-ammonium-containing herbicides. MON 89034 express the Cry1A.105 and Cry2Ab2 proteins to confer protection against certain lepidopteran pests. MON 87411 express the Cry3Bb1 protein to confer protection against certain coleopteran larvae and the DvSnf7 dsRNA confer protection against western corn rootworm, and the CP4 EPSPS protein for tolerance to glyphosate containing herbicides. DAS-40278-9 express the AAD-1 protein to catalyse the degradation of the general class ofherbicides known as aryloxyphenoxypropionates (AOPP) and to confer tolerance to 2,4- dichlorophenoxyacetic acid (2,4-D) herbicides.

Bt11 x MIR162 x MIR604 x MON 89034 x 5307 x GA21 was produced by conventional breeding of the GM maize events Bt11, MIR162, MIR604, MON 89034, 5307 and GA21. Accordingly, Bt11 x MIR162 x MIR604 x MON 89034 x 5307 x GA21 maize produces the transgenic proteins in the individual GM maize events (Cry1Ab, PAT, Vip3Aa20, PMI, mCry3A, MIR604 PMI, Cry1A.105, Cry2Ab2, eCry3.1Ab and mEPSPS). Event Bt11 maize expresses the insecticidal protein Cry1Ab that protects against feeding damage caused by certain lepidopteran pests and the phosphinothricin acetyltransferase (PAT) protein for weed control by providing tolerance to herbicide products containing glufosinate ammonium. Event MIR162 maize expresses the insecticidal protein Vip3Aa20 that protects against feeding damage caused by certain lepidopteran pests and the PMI protein which enables transformed plant cells to utilise mannose as a primary carbon source and therefore used as a selectable marker in the development of the MIR162 maize. Event MIR604 maize expresses the insecticidal protein mCry3A that protects against feeding damage caused by certain coleopteran pests and the MIR604 PMI protein which enables transformed plant cells to utilise mannose as a primary carbon source and therefore used as a selectable marker in the development of the MIR604 maize. Event MON 89034 maize expresses the insecticidal proteins Cry1A.105 and Cry2Ab2 that protect against feeding damage caused by certain lepidopteran pests. Event 5307 maize expresses the insecticidal protein eCry3.1Ab that protects against feeding damage caused by certain coleopteran pests and the PMI protein which enables transformed plant cells to utilise mannose as a primary carbon source and therefore used as a selectable marker in the development of the 5307 maize. Event GA21 expresses the double-mutated 5-enolpyruvylshikimate-3-phosphate synthase enzyme (mEPSPS) for weed control by providing tolerance to herbicide products containing glyphosate.The scientific documentation provided in the application for genetically modified maize Bt11 x MIR162 x MIR604 x MON 89034 x 5307 x GA21 is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in maize Bt11 x MIR162 x MIR604 x MON 89034 x 5307 x GA21 to imply potential specific health or environmental risks in Norway, compared to EU-countries The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of maize Bt11 x MIR162 x MIR604 x MON 89034 x 5307 x GA21 was not performed by the VKM GMO Panel.

Event MON 87429 is a genetically modified maize developed via Agrobacterium tumefaciens transformation. MON 87429 plants contain the transgenes pat, dmo, ft_t and cp4 epsps. Maize MON 87429 encodes the DMO, PAT and FT_T proteins. In addition, maize MON 87429 encodes the CP4 EPSPS protein and utilises an endogenous maize RNAi regulatory element to suppress its expression in pollen. This results in a lack of viable pollen and thus male sterility when MON 87429 plants are exposed to glyphosate-containing herbicides at growth stages ranging from V8 to V13. This is part of a hybridisation system to be used in inbred lines to facilitate the hybrid seeds production. This is not considered an agronomic trait since the application of glyphosate outside the specific growth stages does not lead to male sterile plants but reduces plant yield compared to plants not expressing the same trait. The scientific documentation provided in the application for genetically modified maize MON 87429 is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event MON 87429 to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of event MON87429 was not performed by the VKM GMO Panel
Abstract
Stacked event MON 89034 × 1507 × MIR162 × NK603 × DAS‐40278‐9 (EFSA‐GMO‐NL‐2018‐151) is a genetically modified maize developed via conventional breeding. MON 89034× 1507 × MIR162 × NK603 × DAS‐40278‐9 plants contain the transgenes cry1A.105, cry2Ab2, cry1F, Vip3Aa20, cp4 epsps, pat, aad-1 and the phosphomannose isomerase (PMI) used as a selectable marker in the production of MIR162. MON89034 x 1507 x MIR162 x NK603 x DAS-40278-9 maize provides distinct sources for insect resistance combined with three distinct modes of herbicide tolerance: 2,4-D, glufosinate, and glyphosate. The scientific documentation provided in the application for genetically modified maize is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event maize to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of event MON 89034 × 1507 × MIR162 × NK603 × DAS‐40278‐9 was not performed by the VKM GMO Panel.

Event MON 95379 is a genetically modified maize developed by a two-step process. In the first step, immature embryos of maize inbred line LH244 were co-cultured with a disarmed Agrobacterium tumefaciens (also known as Rhizobium radiobacter) strain ABI containing the vector PV-ZMIR522223. In the second step, selected R2 lines were crossed with maize inbred LH244 line expressing Crerecombinase, which had been transformed with vector PVZMOO513642. In the resulting plants, the CP4 EPSPS-cassette (used for selection of transformed plants) was excised by the Cre recombinase, and the Cre gene was subsequently segregated away, through conventional breeding, to obtain maize MON 95379. Maize MON 95379 expresses Cry1B.868, a chimeric protein containing domains from Cry1A, Cry1B and Cry1C naturally expressed in Bacillus thuringiensis, and Cry1Da_7, an optimised version of Cry1Da carrying four amino acids substitutions to increase its activity. The two Cry proteins expressed in maize MON 95379 provide protection against targeted pests within the order of butterflies and moths (Lepidoptera) including fall armyworm (Spodoptera frugiperda), sugarcane borer (Diatraea saccharalis) and corn earworm (Helicoverpa zea). The scientific documentation provided in the application for genetically modified maize MON 95379 is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event MON 95379 to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of event MON 95379 was not performed by the VKM GMO Panel.

Event MIR162 is a genetically modified maize developed via Agrobacterium tumefaciens mediated transformation of maize embryos. MIR162 plants contain the transgenes vip3Aa20, a modified version of the native vip3Aa1 from Bacillus thuringiensis, and the pmi gene from Escherichia coli. Vip3Aa20 encodes the insecticidal Vip3Aa20-protein, conferring MIR162 with resistance to several species of lepidopteran (order of butterflies and moths) insect pests. Pmi encodes the enzyme phosphomannose isomerase (PMI) which catalyses the isomerization of mannose-6-phosphate to fructose-6-phosphate. PMI was used as a selectable marker during development of MIR162. The scientific documentation provided in the renewal application (EFSA-GMO-RX-025) for maize MIR162 is adequate for risk assessment, and in accordance with EFSA guidance on risk assessment of genetically modified plants for use in food or feed. The VKM GMO panel does not consider the introduced modifications in event MIR162 to imply potential specific health or environmental risks in Norway, compared to EU-countries. The EFSA opinion is adequate also for Norwegian considerations. Therefore, a full risk assessment of maize event MIR162 was not performed by the VKM GMO Panel.
