| Introduction Mixed cropping, i.e. mixing different crops in the same field, provides agronomic advantages as increased productivity under low inputs conditions (e.g. for organic farming: Bedoussac et al. 2015) and higher yield stability (Raseduzzaman and Jensen 2017). In mixed cropping, choosing the right cultivars is critical for the performance of the mixture, as shown for pea-barley mixtures (Hauggaard-Nielsen and Jensen 2001) and maize-bean mixtures (Hoppe 2016). As performance in pure stand can strongly diverge from performance in mixture, estimating the ability of a cultivar to be mixed with another crop is therefore of utmost importance. For this purpose, concepts of General and Specific Combining Ability in hybrid breeding (Griffing 1956) have... |

| Crop mixtures consisting of cereals and legumes have proven as a well-adapted arrangement due to their complementarity towards important resources, especially nitrogen. Crop mixtures combine high yield performance and yield stability. They can contribute to a diversified cropping landscape and adaptation to climate change. The search for alternatives to protein imports from overseas and investments in post-harvest separation technologies are currently fostering their adoption by farmers in Western-Europe, especially under organic and lowinput farming conditions. However, screening and breeding for mixed cropping has hardly been explored for arable crops. Thus, the objective was to develop novel breeding strategies and tools specifically for mixed cropping... |

| Introduction and methods Crop mixtures of cereals and legumes have received recent attention in the scope of climate change and local protein supply. Cereal-legume mixtures are known to increase yield and yield stability compared with pure crops. Thus dedicated breeding strategies for mixed cropping might become necessary. As a model crop, we compared 32 current European spring pea (Pisum sativum L.) and 8 current spring barley (Hordeum vulgare L.) cultivars for their yield performance in mixed and pure stands, with pea as the focal species. Trials were done as an incomplete factorial design (Fig. 1) at two locations in Switzerland with two replications (Fig. 2). We calculated variance components for the general and specific mixing ability (GMA and... |
