Notes and observations

WPB: (Was) the chief stock for oranges in Central Provinces, India. Has a sour fruit with a yellow rind, like a lemon. This looks like C. pennivesiculata.

2/16/1988, EMN: This accession had exocortis, removed by shoot tip grafting. WPB was right (see above). This accession appears to be identical with CRC 2434, C. pennivesiculata, aka C. moi.

12/5/2006, DK & TS: A very large tree for a citron. Fruit oblate, with pronounced nipple; rind thin, looks like a grapefruit inside. Flesh juicy, and very sour. Nicole Barkley's study, Assessing genetic diversity and population structure in a citrus germplasm collection utilizing simple sequence repeat markers (SSRs), says 40% other in genes; We suggest there's some pummelo in there.


Not commercially available in California.
