| 0 | PI 539824 | 'SWINGLE' | Citrus sp. | Florida, United States | RIV | | | 1961 | DEVELOPED | 1907 | | | | | Cultivar | This accession was apparently received as pre-release or 'unofficial' release of 'Swingle' citrumelo for experimental purposes (the official release is PI 539828/CRC 3771). Note from the source history that there was a slight amount of doubt as to its actual identity (also vouched for by a "?" in UC archival materials). It is therefore redundant and was removed from the protected, pathogen-tested collection 2006-05-11. It is still maintained in the field genebank (Citrus Variety Collection). (RRK, 2006-05-11) Note: This is the budsource of 'Swingle' maintained by the UC Riverside Citrus Clonal Protection Program (CCPP). It is unknown at this time why this budsource is maintained rather than VI 356 = RCRC 3771 = PI 539828. Archival CCPP records indicate that VI 143 was obtained from the USDA US Date and Citrus Station on 10/25/1961 and that the donated material was derived from C-57-98-1. Howevere, information from the USDCS Accession Book indicates that C-57-98-1 was derived from "...seed from Texas Exp Sta Rootstock Test Row 34 Tree 8 - Weslaco Texas (Olson) 1/13/58". The period from 1958 to 1961 would not be enough for the material to outgrow its juvenile characteristics although technically it would be producing budwood. The importation of C-58-354 as budwood would presumably not have this issue and so may more probably be the source of this VI. Note that Olson et al (1961) list CPB 4475 as being planted only in 1961 from seed imported from Florida. So, the exact origins of this budline are lost in the shadows of the years. (RRK, 12/2007) There are currently three (apparently redundant) accessions of 'Swingle' maintained at the Repository: the current accession PI 539824/RCRC 3341, PI 539828/RCRC 3771, and PI 539844/RCRC 3767. For more information on 'Swingle' citrumelo in general, please refer to the record for PI 539828/RCRC 3771, the budline maintained at the Repository. (RRK, 01/2008) | 1434760 | PI 539824 |
