Lumia (citrus)
A recent genomic analysis of several species commonly called 'lemons' or 'limes' revealed that the various individual lumias have different genetic backgrounds. The 'Hybride Fourny' was found to be an F1 hybrid of a citron- pomelo cross, while the 'Jaffa lemon' was a more complex cross between the two species, perhaps an F2 hybrid. The Pomme d'Adam arose from a citron-micrantha cross, while two other lumias, the ‘Borneo’ and ‘Barum’ lemons, were found to be citron-pomelo-micrantha mixes.
Kabbad
The Kabbad refers to a citron-like fruit or citrus hybrid which was first described in 1963 by the Moroccan professor Henri Chapot, in his article named ""Le Cédrat Kabbad et deux autres variétés de cédrat"", who remarked it to be a biological hybrid between the citron and the orange sourcing from Damaskus, Syria.
