CRC 3904

PI 539200

VI 431



Photos by Toni Siebert and David Karp, CVC, 5/22/2008. Photo rights. Both on Carrizo, 25 year old trees. 


Source: Received as budwood from Japan via Glenn Dale as requested by W.P. Bitters, 1983.


Parentage/origins:  Parents unknown.


Rootstocks of accession: Carrizo citrange, C-35 citrange


Season of ripeness at Riverside: January to May


Notes and observations:

No virus found in original import (routine Thermo 1546-17, 18) CRC 3275, rec'd 1960, also listed as C. hiroshimana. Should compare this accession with that one when fruit available.

1/18/1989, EMN: Only a few first year fruit, may all be late or off-bloom. Similar but smaller size than fruit on CRC 3275- Check again next year.

2/26/1990, EMN: This accession and CRC 3275 are NOT alike. If this one is true C, hiroshimana (and it should be), then CRC 3275 is probably a chance hybrid seedling. Fruit of this accession is medium-large pummelo sized; rind bright yellow with still some areas of medium green at this time, moderately rough & pebbled. Rind thick. Flesh white, sour, many seeds.


Availability: Not commercially available in California.
