| In organic potato production yields are often reduced by potato late blight (Phytophthora infestans). Two aspects are important in late blight management: a sufficiently high (field) resistance to late blight, and early tuber formation. With early tuber formation the period of tuber growth is extended at the beginning, and with a high resistance level at the end. In 2006 and 2007 experiments were carried out in which the effects of the physiological age of seed tubers on field resistance to late blight and on tuber yield of potatoes (Solanum tuberosum L.) were tested for early and moderately late varieties. The results indicate that with the use of physiologically older seed tubers (by pre-sprouting) the field resistance to late blight is generally lower... |

| The European project LIVESEED (www.liveseed.eu) is based on the concept that cultivars adapted to organic systems are key for realizing the full potential of organic agriculture in Europe. LIVESEED will help to establish a level playing field in the organic seed market across Europe, improve the competitiveness of the organic seed and breeding sector, and encourage greater use of organic seeds by farmers. LIVESEED will improve guidelines for cultivar testing and strategies for ensuring seed health. It will develop innovative breeding approaches suited to organic farming. Finally, it will investigate socio-economic aspects relating to the use and production of organic seed and their interaction with relevant (EU) regulations. The LIVESEED project (2017 –... |

| The organic farming system differs fundamentally from conventionally agriculture in the management of soil fertility,weeds,diseases and pests.Organic farmers depend greatly on conventionally bred and produced varieties,but require varieties better adapted to organic farming systems for further optimisation of organic agriculture.This includes a greater need for ‘reliable ’ varieties contributing to higher yield stability. In this thesis the concept of ‘naturalness ’ as applied in organic agriculture is elaborated and used as a guide to develop concepts and strategies for organic plant breeding and propagation.It refers to ecological and ethical principles,including the non-chemical and agro-ecological approach,and also taking the integrity of life into... |

| Dit rapport is van de Peenrassendemo 2009. Het is een vergelijking van de B-peenrassen voor de biologische teelt. In het project ‘Wie zaait zal oogsten’ is duidelijk geworden, dat een aantal belangrijke hoofdrassen van zaadbedrijven komen die niet biologische willen vermeerderen (o.a. Syngenta). Dit vormt een knelpunt voor voortgang van ontwikkeling richting annex. De resultaten van deze rassendemo zijn tijdens een demomiddag besproken met de telers en de zaadfirma’s met het doel om te kijken of er op korte termijn een geschikt assortiment is te realiseren, of waar er nog specifieke eisen aan deze rassen ontbreken. Met de uitkomsten kunnen zaadbedrijven gerichter werken om een adequaat en sluitend assortiment met biologisch vermeerderde peenrassen te... |
