accessed 2020 Marigoule female flowers may have difficulty getting pollinated if the weather is rainy at the end of spring. It therefore requires the presence of pollinizers (1 row out of 3 planted with Precoce Migoule). Under dry climate and with good pollinators, it is moderately productive. Chestnuts mature medium-early in fall. The nuts fall in the

Its fast growth and the quality of its wood make it interesting for reforestation. It is the hybrid that best resists
