Improved Meyer Lemon

Improved Meyer is a clean-stock clonal selection of Meyer Lemon. UCR records CRC 3737 (VI 319) received as budwood from a CCPP stock plant in 1971. California regulation defines Improved Meyer as specified CVI clones determined free of infection under its testing rules.^⁠[1]⁠[2]

Fruit medium in size, oblong to short elliptical, sometimes faintly ribbed; base rounded, sometimes faintly necked and radially furrowed; apex rounded or with low, broad nipple. Rind thin, soft; surface very smooth; tightly adherent; color yellowish-orange to orange. Segments about 10; axis small and solid. Flesh color light orange-yellow; tender, very juicy; lemon-flavored and acid. Moderately seedy. Crop distributed somewhat throughout the year but mainly in winter.^⁠[1]

Tree moderately vigorous, small to medium in size, spreading, nearly thornless, hardy, and productive. Flowers and new shoot [sic] purple-tinted. More or less everflowering but mainly in spring.^⁠[1]

The Meyer lemon compares favorably with the sweet orange for both cold and heat resistance and thus has a much wider range of climatic adaptation than either the common lemon or lime for which it is used as a substitute. The fruit is remarkably affected by climatic factors and differs greatly in appearance in different regions.^⁠[1]
