| Comments | A market-type lemon. (EM Nauer, 11/13/1989)<P>'Mesero' is the original selection from which all_x000D_ 'Fino' selections, such as <a_x000D_ href="https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?id=1715774">'Fino_x000D_ 49'</a> and <a_x000D_ href="https://npgsweb.ars-grin.gov/gringlobal/accessiondetail.aspx?id=1705132">'Fino_x000D_ 95'</a> originated. All inferior selections of 'Mesero' have been_x000D_ eliminated from Spanish citrus production and, although 'Mesero' and_x000D_ 'Fino' are interchangeable names, 'Fino' is used to avoid confusion_x000D_ (G Ancillo, IVIA, personal communication, 2017-11-28). It should not_x000D_ be confused with the Italian variety 'Primofiore', which refers to_x000D_ fruit produced by all varieties from the first or spring bloom and_x000D_ which mature at about the same time as the Spanish 'Fino'. 'Fino' is_x000D_ thought to have originated as seedling of 'Común' growing in Vega Alta de Segura, Murcia.<P>'Fino' and 'Verna' are the most widely cultivated_x000D_ lemons in Spain, accounting for 30 % and 60 %, respectively, of the_x000D_ cultivated area, the remainder being accounted for by 'Eureka',_x000D_ 'Lisbon', and 'Villafranca'. However, the production area of 'Fino'_x000D_ is less than previously, probably due to consumption of fresh lemons_x000D_ being the harvest season. 'Fino' flowers for shorter time in the_x000D_ spring than 'Verna'. The harvest season of 'Fino' in Spain is_x000D_ October through February, making it the earliest lemon to be_x000D_ harvested, and being grown mostly in valleys with late frosts. The_x000D_ important post-harvest characteristics of 'Fino' as compared to_x000D_ 'Verna' are earliness, persistence on the tree, and maintenance of_x000D_ quality during handling and transportation. Both 'Fino' and 'Verna'_x000D_ are sequentially harvested for size. 'Fino' is said to be preferred_x000D_ by processors due to the time of harvest and fruit quality_x000D_ characteristics; in particular for the higher juice content and acid_x000D_ level and higher essential oil content in the rind. In summer there_x000D_ is a very limited second bloom that results in fruits of larger size_x000D_ the following summer.<P>_x000D_ 'Fino' trees are medium to large in size,_x000D_ consistently productive, thorny, and more vigorous than 'Verna',_x000D_ with more dense foliage and larger leaves than the latter. 'Fino'_x000D_ trees are resistant to humidity and chlorosis, but are more_x000D_ susceptible to cold than 'Verna', although recovering more quickly ._x000D_ 'Fino', like most lemon varieties, is susceptible to mal secco_x000D_ (Saunt, 2000). Unlike 'Verna', 'Fino' does not overgrow sour orange_x000D_ rootstock.<P>_x000D_ 'Fino' fruit are pale yellow, the shape being_x000D_ spherical to oval with a small, sharp nipple and no peduncular_x000D_ collar. The size of the fruit is medium (smaller than 'Verna'), with_x000D_ an average measurement of 54 mm diameterx 69 mm length and an_x000D_ average aspect ratio of 0.8. The skin is thin (average 3.9 mm) and_x000D_ very adherent to the pulp, representing 32 - 36 % of the total fruit_x000D_ weight. The average number of segments is 9. The pulp is pale_x000D_ yellow, with a high juice (50 % of total fruit weight) and acid_x000D_ (0.072) content. The number of seeds per fruit averages 9.6, higher_x000D_ than 'Verna'. (compiled from Hodgson, 1967; Gonzalez-Silicia, 1968;_x000D_ Soler Aznar, 1999; Amoros Castañer, 1999; Agustí, 2000; Saunt, 2000)_x000D_ <P>_x000D_ Field observations in Florida (Ramadugu_x000D_ <i>et al</i>, 2016; Miles <i>et al</i>,_x000D_ 2017) indicated that 'Mesero' was somewhat tolerant of Huanlongbing_x000D_ (HLB), but not among the most tolerant genotypes, and it was not_x000D_ resistant to HLB.
