Conservation of Reliable Vegetable Varieties

Any existing variety that can produce yet a new plant that is true to type (the offspring is equivalent to its parent) from its seed, is an “open-pollinated” variety.  This means that the further cultivation of the crop is possible after harvest of the seed, and cultivation in the following year. If, however, the seeds used for multiplication were collected indiscriminately – in particular in the case of cross-pollinators (allogamous) – the characteristic properties of the variety could be lost. To maintain cultivars, special care must be taken in the production of their seeds: every breeder therefore selects only from plants that are well-formed, healthy and true to type for the production of “elite seed” (base seed) in maintenance breeding. This elite seed is then sown by seed multipliers for the production of sale seed.

The basis of our work is the long-term maintenance breeding of our varieties under organic and biodynamic conditions of agriculture. In this way, the varieties remain in a continuous, natural flow of germination, growth, fruiting, and decay. This is a favorable prerequisite for the plants to be able to deal with constantly changing living conditions, and to internalize them.  Open-pollinated varieties, which have proved to be particularly successful under competitive production conditions, are distributed by Kultursaat to organic or biodynamic farms that commit themselves to the maintenance breeding of those varieties. In this way, biodiversity can be leveraged, since these varieties for organic environments are made available for small and professional gardeners.
