Notes and observations
12/7/1989, EMN: Originated from seed 1915. This accession had psorosis which was eliminated by thermotherapy (Thrmo 1176-5) This appears to be an ordinary navel with no special attributes. Why keep it if it hasn't become a national landmark yet?
12/7/1989, EMN: Is among best yielding strains in "navel yields in smog" experiment in the Rubidoux screenhouse.
Not commercially available in California.
