| The strawberry (Fragaria × ananassa) cultivars ‘Suvetar’ and ‘Valotar’ have been released from the breeding programme of MTT Agrifood Research Finland. Both new cultivars overwintered as well as the control cultivars ‘Jonsok’ and ‘Polka’. ‘Suvetar’ overwintered even better than ‘Polka’. ‘Suvetar’ was produced from the cross ‘Polka’ × ‘Emily’. It scored better than the control cultivars for sensory assessed skin resistance. Measured fruit firmness of ‘Suvetar’ was not significantly different from that of ‘Polka’, but was better than ‘Jonsok’. ‘Valotar’ originates from a cross between ‘Jewel’ and ‘Senga Sengana’. Its measured fruit firmness was better than that of ‘Jonsok’ and ‘Polka’. Considering sensory assessments, the good firmness seems to be largely... |

| For further optimisation of organic agricultural systems, more focus is required on organically produced seeds and the development of better adapted varieties. Organic plant breeding and seed production need to comply with the concept of naturalness as applied in organic agriculture, which not only includes the nonchemical and agro-ecological approaches, but also the integrity of life approach. As organic environments are less controllable and are more variable, breeding should aim at improved yield stability and product quality by being adapted to organic soil fertility as well as sustainable weed, pest and disease management. Also the ability to produce economicacceptable seed yield avoiding seed-borne diseases should be included. On the short... |

| Background and Aims A number of root and root hair traits have been proposed as important for acquisition of P. However, it remains unknown whether these traits are most important in determining macro- and micronutrient uptake at low soil fertility. This study investigated the variations in root and root hair traits among spring wheat genotypes and examined which root and root hair traits are most important for high uptake of macro- and micronutrients. Methods Six spring wheat genotypes were grown in a soil with low nutrient availability. The root and root hair traits as well as the content of macro- and micronutrients were identified. Results A significant genetic variability in root and root hair traits was found. High root growth vigour and long and... |

| A field trial with carrots was carried out in 1998 at two sites in Hesse (North: loamy soil in Neu-Eichenberg; East: sandy soil in Queck) to compare 6 open pollinating and 6 F1 hybrids under an Organic Farming regime. Characteristics of cultivation, harvest, quality, and longevity were measured. Of the parameters of cultivation and harvest the hybrids showed a more intensive foliage growth, higher marketable yields (plus 29 and 25%), and more homogeneous taproots than the open pollinating cultivars. Picture forming methods clearly separated the samples into the two groups of breeding methods. The open pollinating cultivars were characterized by higher degrees of form intensity and ripeness and a stable vitality. The hybrids of the sandy site had a better... |

| Seed-the source of life. And woman holds the seed with the hope of new life. Instead of producing diverse seed from homestead agriculture, women are engaged traditionally to select seed, drying, preserving, protecting during storage, saving them from any economical crisis of the family. To ensure the seed quality and the perfect storage place & methods, women hold the vast knowledge. They decide the quantity and variety of seed to be saved and the method of preservation. Seed selection by women is a continuous activity. Working in the fields, they observe the plants and decide which seeds to select. They identify plants of good quality on the basis of size, grain formation and their resistance to pests and insects. Here a woman looks at the seed... |

| There are numerous instances in which induced plant resistance responses (IR) have been demonstrated. However, before IR can be made use of in practice it is important to understand as much as possible the ecology and genetics of the inducing agents and their interactions with plants and pathogens. Effects of host genetic background were tested with thirteen tomato varieties and two isolates of Phytophthora infestans. Isolate effects on inducibility were tested with six varieties and six pathogen isolates. Leaf disks of plants that had been treated with BABA (DL-3-aminobutyric acid) or water were inoculated seven days later with 20 µl sporangial solutions of 5*104 sporangia ml-1. All experiments were repeated three times with six replications each.... |

| Genetically diverse Composite Cross Populations (CCPs) may be useful in environmentally variable low-input systems as an alternative to pure varieties. They are formed by assembling seed stocks with diverse evolutionary origins, recombining these stocks by hybridisation, bulking the F1 progeny, and subsequent natural selection of the progeny in suc-cessive natural cropping environments. CCPs derived from either 10 high yielding parents (YCCPs), 12 high quality parents (QCCPs), or all 22 parents (YQCCPs), were grown at four sites (2 organic, 2 conventional) in the UK. The YCCPs out yielded the QCCPs, which had higher protein concentrations and Hagberg falling numbers. Although the CCPs performed within the range of the parents, they often performed better... |

| Organic cotton production currently takes place in 22 countries resulting in 241’697 metric tons of fibre and 1.1% of the global cotton production (Truscott et al. 2010). Up to 80% of world’s organic cotton is produced in India. However, this market is threatened due to the displacement of traditional cotton species and cultivars by genetically modified (GM) hybrids selected for high input farming. Organic cotton farmers are facing increased difficulties in finding suitable cultivars in India (Nemes, 2010). Moreover, there is a big risk of physical and genetic contamination of organic cotton with GM cotton and the loss of locally adapted genetic resources. Therefore fast action is needed to re-establish a GM-free seed chain and breeding programs for... |

| Glomus intraradices, an arbuscular mycorrhizal fungus (AMF), is frequently found in a surprisingly wide range of ecosystems all over the world. It is used as model organism for AMF and its genome is being sequenced. Despite the ecological importance of AMF, little has been known about their population structure, because no adequate molecular markers have been available. In the present study we analyse for the first time the intraspecific genetic structure of an AMF directly from colonized roots in the field. A recently developed PCR-RFLP approach for the mitochondrial rRNA large subunit gene (mtLSU) of these obligate symbionts was used and complemented by sequencing and primers specific for a particularly frequent mtLSU haplotype. We analysed root samples... |

| State of the Art: World-wide there is very little cultivar testing of pipfruit under the conditions of organic farming. No rare there appropriate breeding programs on-going. Thus, knowledge is very scare. Definition of the problem: Pipfruit as apple and pears are difficult to produce organically. A key disease is scab (Venturia sp.); but also susceptibility to leaf spot disease, monilia, sooty blotch disease, aphids, insects, biennial bearing, cracking etc. are major problems to overcome with organically approved methods and products. Additionally, also organic pipfruit have to achieve the high and significantly increased expectations in terms of outer and inner quality. Project aims: To find apple and pear cultivars suited for organic... |

| Eine wichtige Anpassung an den ökologischen Anbau ist eine zügige Frühentwicklung und ein Wurzelsystem, das an organische Düngung angepasst ist. Eine Halbdiallelkreuzung aus insgesamt 20 europäischen Winterweizensorten wurde 2001 hergestellt und insgesamt drei Subpopulationen aus neun Hochertragseltern (CY), eine mit 12 Backqualitätseltern (CQ) und eine aus allen Eltern (CYQ) zusammengestellt. Seit der F5 wird Saatgut unter konventionellen und ökologischen Anbaubedingungen in jeweils zwei parallelen Populationen getrennt nachgebaut. Saat jeder Generation wird bei -20o C aufbewahrt. Für die Versuche wurden Generationen F6, F10, F11, F15 in einem Feld zu F6.1, F10.1, F11.1, F15.1 vermehrt. Frisches Saatgut wurde im Hydrokultursystem zwei Wochen bei 18/12 oC... |

| Für den ökologischen Anbau von Hafer stellt der Haferflugbrand ein wirtschaftliches Risiko dar, da Flugbrand den Ertrag reduziert und die Saatguterzeugung gefährdet. Ein effektiver Lösungsansatz für dieses Problem wäre eine gezielte Resistenzzüchtung, wofür grundlegende Fragestellungen im Rahmen des Projektes zu untersuchen waren. So war eine Resistenzprüfmethode zu etablieren, ein breites Hafersortiment auf Resistenz zu prüfen und verschiedene geografische Herkünfte von Ustilago avenae hinsichtlich ihrer Virulenz zu testen. Am Ende des Projektes sollten die Chancen für eine erfolgreiche Resistenzzüchtung eingeschätzt werden können. Die Inokulationsmethode auf der Basis der vakuumgestützten Infiltration des Saatgutes konnte etabliert und optimiert... |
