History & Origin

Nemaya הוא בעצם זן רובוסטה (Coffea canephora) ולא ערביקה. הוא נוצר מהצלבת C. canephora T3561 ו-T3751 על ידי PROMECAFE-CIRAD-CATIE. תפקידו ייחודי: אינו מיועד לייצור פולים, אלא משמש כ-rootstock, בסיס שעליו מרכיבים זני ערביקה כדי להעניק להם עמידות לנמטודות. הרכבה של ערביקה על שורש Robusta אינה משפיעה על איכות הספל. הוא עמיד ל-Pratylenchus spp., Meloidogyne exigua, M. arenaria ו-M. paranaensis, קבוצת נמטודות נפוצות בקפה.
