OBSERVATIONS ON A MUTATION OF A VERY EARLY PEAR VARIETY

Article number

Abstract

En 1970 nous avons isolé une mutation de la variété de poirier "Mirandino Rosso" aux charactères morphologiques assez differents de ceux de la variété d’origine (entre-neuds raccourcis, feuilles, fruits et fleurs plus grands). D’autres caractères favorables sont restés inchangés.
La nouvelle forme est pratiquement auto-incompatible et incapable de donner une production suffisante par vois parthénocarpique.
Elle presente un procéssus méiotique anormal, produisant des grains de pollen difformes et à faible capacité germinative, et est tetraploïde.
