Genoa Lemon

UCR describes Genoa as a California variety of the Eureka type and traces its introduction from Genoa, Italy, to California around 1875 by José Rubio. Hodgson’s index directs “Genova” to “Genoa.” The UCR record notes shellbark and exocortis in tree 12A-2-14 and says exocortis was removed from the accession by shoot-tip grafting selection STG 93-3 in 1985.^⁠[1]⁠[3]

An EEAOC compatibility matrix marks Rich 16/6 (USA) as compatible with Genoa lemon. The cited table gives no sample size or trial method.^⁠[2]

Secondary profiles describe Genoa as densely foliated and spreading more than it rises, with spike-free branches. Tree Crops NZ compares its smaller stature and wider habit with Eureka, notes that fruit outside the canopy is susceptible to wind-rub, and gives July–December fruiting for New Zealand. These are regional and secondary descriptions, not trial measurements.^⁠[5]⁠[6]
