| Résumé : |
In the two seasons of data collection during this initial study, there were no significant yield differences either between prereleased varieties alone or between prereleased varieties and the local control. A further comparison between research and farmer yield results shows a higher yield gap for the prereleased varieties than for the local control. This indicates that, unlike the prereleased varieties, the local control might do almost as well under the worst and the best management conditions.
On a yield basis, there is a strong case for farmers to continue using Segaolane but, taking color and taste of porridge as indicators, farmers prefer Macia, suggesting that this variety may be used as a food-crop substitute for Segaolane. SDS 2583, a malting variety with red grain and bitter porridge, is the least preferred by farmers as a food crop.
The limited duration of this study means that its results can be regarded as only indicative and , therefore, that more data collection and analysis are needed.
