Le Chasselas Gros Coulard est une mutation tétraploïde comme le prouvent la numération des chromosomes et l' examen des caractères secondaires comme la taille des stomates, des pépins et des baies, le nombre de chloroplastes des cellules péristomatiques.Il est probablement possible d'obtenir par semis des types tétraploïdes plus fertiles. Ceux-ci présenteraient un gros intérêt pratique pour la production du raisin de table, du fait de la taille de leurs baies.
