Summary

Practical recommendations
● Keep a seed sample for each year
● Avoid practices that are too selective (i.e. removing small seeds at cleaning stage)
● Record crop performance and climate data in a field book

Liveseed Practice Abstract 52
Target audience: farmers, seed networks, seed producers

EPrint Type:Practice tool
What problem does the tool address?:Organic cereal seed production of heterogeneous populations may appear simpler than uniform varieties,
however, to produce quality seeds of locally adapted cereal population, skills and attention are needed.
What solution does the tool offer?:1. Maintain the original source: It’s good practice to grow a plot of the original population large enough to ensure seed for a field. 1.000 m2 should provide enough seed for 1 ha the following year. Within this nucleus carry out quality controls: remove plants of foreign species and carefully check for diseases. Take every precaution at harvest to avoid contamination with external seed (combine, thresher, etc.).
2. Foster local adaptation: Start off with the highest possible level of intra-population diversity, avoid excessive selective pressure during first crop cycles, keep a backup of last year’s seed in case of severe reduction in yield. As seed is bulking up, move towards your target microenvironment and allow the crop to naturally evolve
3. Select new cultivars: Select the best plants in the field but harvest only the top half of the ear to avoid removing genetics from the original source. Promising pure lines can be kept separate or mixed together to create multi-line mixtures.
