Notes and observations

RRK, 8/14/2017: "This is a selection of 'Thomson Improved' that was cleaned up at CCPP for Michaelis Nusery in the 1990 VI index but was not assigned a VI identifier at that time. It was released for general distribution in 2009 and VI 795 was assigned 06/2009. The 'Rush' selection of TI apparently originated in the Porterville area but additional information is not available at this time. 'Thomson Improved' selections in general are up to 14 days earlier than 'Washington' navel, but fruit color, quality, and yield, as well as tree vigor, are inferior to 'Washington' navel (Hodgson, 1967, p 483; Saunt, 2000, p 21)"
