Comparative Study of Indigenous and Exotic Mango (Mangifera indica) Varieties on Farmer Preference in Ogun State

Mango (Mangifera indica) is the most widely consumed tropical fruit in Nigeria, with production spread across multiple agro-ecological zones, including Ogun State in the South West. While improved exotic mango varieties have been introduced by research institutions to boost yield and quality, farmer adoption remains uneven, often driven by cultural preferences, market demands, and observed agronomic performance rather than formal extension recommendations. This study compares farmer preference for three exotic varieties (Julie, Peter, and Keitt) against two indigenous landraces (Ijoko and Ogbomosho) in Abeokuta, Ogun State, using a participatory variety selection approach. A total of 80 mango farmers from four communities participated in field evaluations and scored varieties based on taste, fruit size, yield, disease resistance, and market price received. Data were analyzed using descriptive statistics and a preference ranking index. Results indicate that Julie ranked highest among exotic varieties due to its flavor and market price, while Ijoko landrace was preferred for disease resistance and early bearing. Farmers expressed interest in grafted Julie plants but cited high planting material cost as a constraint. The study recommends subsidized distribution of grafted exotic variety seedlings and community nursery programs to facilitate improved mango variety adoption in Ogun State.
