Notes and observations:

EMN, 1986: Small, seedy navel. From multiple seedlings. This accession had exocortis which was removed by shoot tip grafting (STG 144-6). 44944-A was listed on the old accession card as an F.P.I. number; however, I think it is more likely to be a CPB number. Or, it could have been PI 244944 and the "2" got lost in the shuffle; this may be most likely since the 244,900 series of PI numbers were dated January 1958; but no PI card could be found on PI 244944. Or, it could have been seed from CPB 44944 trees which had been growing in Texas since about 1917 when CPB 44944 was introduced.

EMN, 2/12/1988: A typical young budline navel. Good fruit size, large navel structure on many fruits, rind somewhat rough and ridged at the stem end. Usual internal navel orange appearance and flavor. Most fruits seedless but a few with 1 or 2 seeds each. Nothing special about this budline--why keep it?

 

Availability: Not commercially available in California.
