Genome resource reviewed against the CGD assembly record and existing variety identity. The sequenced citron is Corsican, whereas this Etrog record represents different citron material. Use it for Citrus medica comparisons, not as a genome of this Etrog accession.

The page identifies its subject as Etrog citron and gives an arboretum plant label: donated by CRFG/Haluza, planted in 1983. Its general Etrog description characterizes the fruit as lemon-like and oblong to oval, with very thick fleshy peel and pale-yellow to greenish pulp divided into as many as 20 segments; it says the fruit is not very juicy and has many seeds. The page does not identify the plant as UCR CRC 3891, so these are claims about the page's Etrog account, not accession-specific traits.

Primary cultivar-specific experimental evidence. Table 1 classifies embryo number and male fertility; embryo means were measured under a stereoscopic microscope in twenty seeds per cultivar, except Foster Pink and Marsh whose embryo count was not examined. Table 2 reports selected zygotic progeny from controlled crosses; it is not a percentage of all seeds that are zygotic. Material grown at Sasaguri Orchard, Kyushu University Farm, Fukuoka, Japan. Preserve the difference between parent fertility and male fertility segregating among offspring. DOI:10.2503/jjshs1.82.203.
