Au cours du second trimestre, l'activité a été quasiment stable (-0,6 % à données comparables), après plusieurs trimestres de progression extrêmement soutenue. Le ralentissement constaté concerne principalement le continent européen et notamment l'Europe du Sud (Italie et Espagne), affectée par des conditions climatiques défavorables pour certaines productions maraîchères. Il traduit également certaines anticipations et décalages d'activité ainsi que la baisse pilotée de l'activité de fourniture agricole de la Business Unit Vilmorin-MKS au Japon. Sur l'ensemble du semestre, la croissance reste élevée et concerne la plupart des zones géographiques - en particulier l'Amérique du Nord et l'Amérique Latine - et des espèces stratégiques, avec de belles progressions en piment/poivron, carotte, courgette et concombre. 4e semencier mondial, Vilmorin & Cie crée des semences potagères et de grandes cultures à haute valeur ajoutée, contribuant à répondre aux enjeux alimentaires.  Soutenue par son actionnaire de référence Limagrain, groupe coopératif agricole international, la croissance de Vilmorin & Cie s'appuie sur un investissement soutenu en recherche et une stratégie d'internationalisation affirmée, pour renforcer durablement ses positions concurrentielles sur des marchés mondiaux porteurs.

SALES FOR THE 1ST SEMESTER ENDING ON DECEMBER 31, 2016 UP 10.2% WITH CURRENT DATA STRONG IMPROVEMENT OF RESULTS FOR THE 1ST SEMESTER 2016-2017 On average, sales for the first semester globally represent around one third of the annual sales for Vilmorin & Cie. Because of this highly seasonal pattern, the consolidated financial statements for the first semester traditionally show very negative income. The consolidated financial statements for the first semester 2016-2017, closed on December 31, 2016, were approved at the Vilmorin & Cie Board meeting of February 14, 2017. The Statutory Auditors have carried out a limited audit of the financial information for the first semester; in their conclusions they have not indicated any reservations or particular remarks. Consolidated financial information is established in compliance with the IFRS referential (International Financial Reporting Standards) as endorsed by the European Union on December 31, 2016. The accounting methods and principles adopted in the consolidated financial statements for the first semester on December 31, 2016 are identical to those used in the consolidated financial statements for the fiscal year closing on June 30, 2016. Thus, no change in accounting methods or estimates with any impact on Vilmorin & Cie's consolidated financial statements was applied by Vilmorin & Cie over the course of the semester. Evolution of the data for the semester is analyzed using current data and on a like-for-like basis. Comparable data is restated with constant scope and currency impact; accordingly, the result for the first semester 2015-2016 takes into account in particular the impact of changes in currency translation, by applying the average rate on December 31, 2016 to the income statement on December 31, 2015. The activity of the company Genica Research (United States. Vegetable Seeds), acquired in February 2016, has not been restated for scope for fiscal year 2016-2017, since the company's American activities were integrated into the HM.CLAUSE Vegetable Seeds Business Unit while its European activities into that of Vilmorin-MKS. SaleS for thE FIRSt SEMESTER: VERY DYNAMIC GROWTH MARKED BY A PERFORMANCE OF EXCELLENT QUALITY for THE FIELD SEEdS ACTIVITY Vilmorin & Cie's consolidated sales for the first semester of 2016-2017, closed on December 31, 2016, came to 503 million euros, a rise of 10.2% with current data and 10.8% on a like-for-like basis. VEGETABLE SEEDS DIVISION: A FIRST SEMESTER WITH SIGNIFICANT GROWTH IN SPITE OF A SLOWDOWN IN BUSINESS OVER THE 2ND QUARTER Sales for the Vegetable seeds division for the first semester came to 286.9 million euros, an increase of 5.7% with current data compared with the first semester for 2015-2016. Restated on a like-for-like basis, the division achieved an increase of 5.2 %. During the course of the second quarter, business was practically stable (-0.6% on a like-for-like basis), after several quarters of extremely strong progression. This slowdown mainly concerns Europe, and particularly southern Europe (Italy and Spain), affected by unfavorable climate conditions for certain vegetable productions. It also conveys the anticipation and offset of certain business operations and the programmed drop in the agricultural supplies activity of the Business Unit Vilmorin-MKS in Japan. This performance therefore does not cast any doubt on Vilmorin & Cie's growth impetus for this activity or its global sales growth objective for fiscal year 2016-2017. Over the full semester, growth remains high and concerns most geographical zones - particularly North America and Latin America - and strategic crops, with fine progression of hot and sweet pepper, carrot, summer squash and cucumber. FIELD SEEDS DIVISION: SUSTAINED GROWTH IN BUSINESS, DRIVEN BY STRONG DYNAMIC BUSINESS IN SOUTH AMERICA Sales for the Field seeds division for the first semester came to 201.6 million euros, an increase of 18.2% compared with the first semester for 2015-2016; this increase was 21% on a like-for-like basis. In Europe, on a rapeseed market characterized by the continuing adoption of hybrid seeds, the commercial campaign for this crop achieved an excellent level of growth, both in terms of volume and value, resulting in market share gains. Vilmorin & Cie thus confirmed its position as a top-ranking European player. The first part of the straw cereal seed campaign (wheat, barley) recorded a marked drop in sales, in a market context where the use of commercial seeds has fallen, particularly in France. In a market environment still heavily influenced by the low level of prices for agricultural production, orders for corn are lower, in line with the falling trends for cultivated acreage for this crop, particularly in Western Europe. However, orders to date for sunflower seeds are promising, particularly in Eastern Europe. In South America, the first corn campaign in Brazil (safra) was considerably higher than the previous year, with an increase both in volume and in value, in line with market trends, while the second corn campaign (safrinha) has also made a very good start, partly through anticipation of the sales campaign. In the other new development zones (Asia and Africa), the level of business achieved overall during the first semester corresponds to expectations. The Field Seeds division thus recorded sales for the second quarter up 29.5% on a like-for-like basis. Finally, on the North American market, the beginning of the commercial campaign for corn and soybean seeds is running well, in the context of a drop predicted for corn acreage, benefitting an increase in soybean acreage. RESULTS FOR THE FIRST SEMESTER: A STRONG IMPROVEMENT Directly linked TO THE INCREASE IN BUSINESS AND TIGHTER management of OPERATING CHARGES After taking into account the cost of destruction and depreciation of inventory, margin on the cost of sales came to 246 million euros, representing 48.9% of total sales, down 1.1 percentage point compared to the first semester for the previous fiscal year; it was mainly affected by the business mix. Net operating charges came to 264.5 million euros, an increase of 4.2 million euros compared with the first semester for fiscal year 2015-2016, including an additional investment of 6.4 million euros in research and development. Consequently, the operating income for the first semester shows a loss of 18.5 million euros on December 31, 2016, a strong reduction (13.4 million euros compared to the first semester for 2015-2016); the operating margin, traditionally negative at the end of the first semester, came to -3.7%, as opposed to -7% on December 31, 2015. The income contribution from associated companies, in particular AgReliant (North America. Field Seeds) and Seed Co (Africa. Field Seeds), stood at -24.9 million euros at the end of the first semester for 2016-2017, virtually the same level as at the end of the first semester for the previous fiscal year. The financial income shows a net charge of 6.8 million euros as opposed to 22.9 million euros on December 31, 2015. In particular, this year foreign exchange gains of 4.1 million euros were recorded, as opposed to foreign exchange losses of 5.4 million euros for the previous fiscal year. Income tax on December 31, 2016 shows a net tax income of 10.5 million euros, a decrease of 5.9 million euros compared to the previous year. As a result of these factors, the net result for the semester shows a loss of 39.7 million euros, including a group share loss of 38.8 million euros, a reduction of 22.9 million euros compared with the first semester for fiscal year 2015-2016. At the end of December 2016, the balance sheet structure is naturally influenced to a large extent by the seasonal nature of the annual business cycle. Net of cash and cash equivalents (224.9 million euros), financial indebtedness came to 988.8 million euros, including a non-current share of 884.1 million euros. The group share of equity stood at 1,112.6 million euros and minority interests at 109.1 million euros. In view of the results for the first semester, as presented above, and on the basis of information currently available, Vilmorin & Cie confirms its global sales growth objective for fiscal year 2016-2017 at +5% on a like-for-like basis compared with fiscal year 2015-2016. Vilmorin & Cie has also fixed the objective of achieving a current operating margin rate at the same level as that of fiscal year 2015-2016. Over the second semester, reaching these objectives will nevertheless partly depend on the definitive evolution of cultivated acreage and prices for agricultural production, in a context of pressure on pricing policies for the Field Seeds activity, and also on the confirmation of growth potential for the Vegetable Seeds activity demonstrated over recent fiscal years. You can consult a presentation of sales and results at the end of the first semester as of 9:00 am on the website www.vilmorin.info Thursday February 23, 2017: registration with the AMF of the update of the annual report for 2015-2016 Tuesday April 25, 2017(1): sales at the end of the third quarter 2016-2017 Monday July 31, 2017(1): sales for the fiscal year 2016-2017 Wednesday October 18, 2017(1): results for the fiscal year 2016-2017 (1) disclosure after trading on the Paris stock market.

A common strategy to create high-yielding plants is hybrid breeding - crossing two different inbred lines to obtain characteristics superior to each parent. However, getting the inbred lines in the first place can be a hassle. Inbred lines consist of genetically uniform individuals and are created through numerous generations of self-crossing. In maize, the use of so-called "haploid inducers" provides a short cut to this cumbersome procedure, allowing to produce inbred lines in just one generation. A study by Laurine Gilles and colleagues, published today in The EMBO Journal, sheds light on the genetics behind haploid induction. "Knowing the molecular identity of haploid induction represents an important breakthrough to fully understand the fertilization process in plants, and hopefully will allow to translate this breeding tool to other species," said the study's senior author Dr. Thomas Widiez, an INRA (Institut National de la Recherche Agronomique) researcher at the École Normale Supérieure in Lyon, France. Haploid inducers were first discovered in the 1950s. Pollination of female flower with pollen of a haploid inducer strain will yield offspring that are haploid, meaning that they will only contain one single copy of each gene as opposed to the usual two copies. All their genetic material comes from the mother. Treating these haploid plants with a chemical that causes chromosome doubling will lead to plants with two identical copies of all genes in just one generation. With classical inbreeding, this condition takes seven to ten years to achieve. Haploid offspring in maize are not unusual; they emerge naturally, albeit at a very low rate. Haploid inducers can bring this rate up to about 10% of the progeny being haploid - enough to make it a useful tool for breeders. More than 50 years after the discovery of haploid inducers, Widiez and his team, in collaboration with Limagrain, have now identified the gene that mainly causes the phenomenon and termed it Not Like Dad to highlight the fact that its dysfunction induces embryos without genetic contribution from the father. The gene product is necessary for successful fertilization so that its failure promotes the formation of haploid embryos. Two other research groups have in parallel identified the same gene and come to similar conclusions. Haploid inducers are nowadays powerful breeding tools, but as yet the technology is restricted to maize, while in-vitro haploid induction in certain crops is labor-intense. Understanding the genes and molecular mechanism behind the process will help translate this technology to other crops. The identification of Not Like Dad is an important step to this end. While Not Like Dad is the most important contributor to haploid induction in inducer lines, there are at least seven more genes that play a role in increasing the rate of haploid offspring. Revealing their molecular identity, as well as understanding their mode of action, will be important to fully understand the process.
