Comparison and adaption of open pollinating varieties of carrots to drougthstress and to the location Marchfeld for organic farming
Abstract
Target groups are plant breeders for organic farming, advisors, organic farmers and people interested in food quality. Opponents to hybrid varieties claim that heterosis puts an emphasis on biomass accumulation and yield but the more subtle aspects of ripening and creation of aroma are neglected in hybrid varieties. Project aims: + characterize open pollinating varieties and one F1-variety as reference of carrots in a 3-year field trial. Agronomic, analytical and sensory parameters are collected. + find the variety that copes best with environmental influences in Marchfeld and that has the best tolerance to drougthstress + messure the consquences of reduced irrigation to sensory and analytical parameters + high quality products can be offered of an open pollinating variety for common markets After the first year the best varieties are selected and reproduced in the second year beside the field trial and comparison of the varieties. The third year the reproduced varieties again are tested in a field trial with different irrigation variations. Methodology: Field trial: 1 site, three years One F1 variety (Maestro) as reference and 5 open pollinating varieties (Nantaise 2 Milan, Nantaise 2 Beate, Nantaise 2 Fanal, Nantaise 2 Fynn, Nantes 2 Rotin) Irrigation: 3 different water amounts (standard and 2 reductions) Parameters: plant production parameters (yield and proportion of marketable carrots, germination capacity, leaf and root diseases, root quality, homogeneity, shelf life) Nitrate, Ascorbic acid, potassium, Brix, malic acid, Saccharose, Glucose, Fructose, !- und "-carotene, phosphate, proline accumulation Bend test L*a*b-colour measurement Sensory tests: tastings Economic calculation: amount of coverage
