Five Nigerian Citrus Sweet orange local land races namely: Agege I. Umudike. Bende. Etir,an and Meran were screened on two commonly used citrus rootstocks in Nigeria. The rootstocks are Cleopatra mandarin (Citrus reshni Hart. Ex Tan) and Rough Lemon (Citrus jambhiri I. Lush) with the aim of rapid production of good quality Sweet orange budlings for orchard establishment. The five sweet orange local land races served as the subplots and the two commonly used rootsiocks were used as the main plots. The experimeiital design was a split plot in randomized complete block.
Percentage budtake was almost one hundred percent for all the scions and roolstocks used. There were also no significant differences in the percentage budsuccessibreak 28days after budding. On the later growth for the scion length, Agege I. Umudike and Meran varieties performed better in growth vigour, while Bend& recorded the lowest growth attributes. However, only Agege I and Meran cultivars had the 450cm scion length recommended for orchard establishment wentyfour weeks after budding. Rough lemon rootstock was found to impart more vigour on its scion than Clcoprnra mandarin.
Agege I and Meran Sweet orange cultivars produced the best scion growth attributes and rough lemon rootstock imparted the best vigour on scions.
