Higher caffeine content and cup beverage bitterness considerably depreciated the commercial value of Coffea canephora Pierre (CAN) compared with C. arabica L (ARA). Wild caffeine-free species like C. pseudozanguebariae Bridson (PSE) offer the opportunity to produce new CAN varieties containing little or no caffeine. F1 plants resulting from a PSE × CAN cross, and BC1 individuals, derived from the first backcross generation (PSE × CAN) × CAN) were produced. In order to assess flowering phenology and yield traits in F1 and BC1 hybrids, six morphological characters including flowering time, pollen viability (PV), fructification rate (FR), seed set (SSET), flower number per node (NFN) and 100-bean weight (W100) were studied under environmental conditions in Côte d’Ivoire. The results showed that F1 plants flowered only in February while, for BC1, 20% and 80% of the plants flowered in January and February, respectively.
