Le grand c\u00e9page l\u00e9manique n&#8217;y est pas pr\u00e9sent en tant que c\u00e9page, mais comme parent du porte-greffe 41B Millardet et de Grasset. Obtention r\u00e9alis\u00e9e en 1882 par Alexis Millardet et Charles de Grasset, ce porte-greffe est un croisement entre le Chasselas et un Vitis Berlianderi, une vigne am\u00e9ricaine r\u00e9sistante au phyllox\u00e9ra. Il se caract\u00e9rise selon le site Plant Grape par &#8220;son adaptation aux sols calcaires et sa r\u00e9sistance \u00e0 la chlorose. Il r\u00e9siste jusqu\u2019\u00e0 60% de calcaire total, 40% de calcaire actif et \u00e0 un IPC de 60. Il absorbe \u00e9galement bien le magn\u00e9sium dans le sol. Le 41 B MGt est par contre sensible aux conditions temporaires d\u2019exc\u00e8s d\u2019humidit\u00e9 au printemps et sa r\u00e9sistance \u00e0 la s\u00e9cheresse est moyenne. Il se montre peu adapt\u00e9 aux sols trop compacts.&#8221;<\/p>\n<p style=\"text-align: justify;\">Fiche d\u00e9taill\u00e9e du <a
