Source: Received as budwood from Japan, via Glen Dale & CCPP, 1979.

 

Parentage/origins: Reported to be a graft chimera of a satsuma mandarin and Citrus natsudaidai

 

Rootstocks of accession: Carrizo citrange, C-35 citrange

 

Season of ripeness at Riverside: October to November

 

Notes and observations:

There are two cultivars of naturally occurring chimeras [in Japan], Kobayashi Mikan and Kinkoji Unshiu, and their characteristics have been maintained for over 70 years in Japan. Both are considered to be periclinal chimeras that develop spontaneously at the graft union. Isozyme analysis has confirmed that 'Kobayashi Mikan' consists of L-1 derived from 'Satsuma' mandarin and L-2/L-3 from 'Natsudaidai' (C. natsudaidai" (Yamashita, 1983 quoted in Sugawara et al, 2002). See also Yamashita (1979, 1983) and Samura and Nakahara (1928).

 

This is reported to be a graft hybrid. This accession received thermotherapy during processing as a foreign import.

EMN, 9/1988: This is probably (according to WPB) a graft hybrid of C. natsudaidai + Satsuma.

EMN, 1/20/1989: Most resembles a medium-small, oblate, medium orange color, moderately rough rinded mandarin. Orange flesh, moderately seedy, tart but could be considered edible in a pinch.

Availability: No longer commercially available in California. This accession no longer has an approved budsource. Please refer to the CCPP for information on another approved budsource or to start a reintroduction inquiry.
