Stated to be a "seedless tangelolo" by donor and to be "sibling of USDA 77-19, fewer seeds than 77-19, flavor not as good as 77-19, larger fruit than 77-19". (RRK, 03/2004) Very weak tree; reintroduced as RRUT 286 but retained as RRUT 286 did not establish and RRUT 226 became more robust. (RRK, 07/2004)
Reintroduced again as RRUT 317. However, RRUT 317 also became weak and RRUT 226 was retained as the most robust introdution. (RRK, 11/2004)
Although the source trees of this accession perished in the Great Greenhouse Meltdown of 2007, thermotherapied propagations (and thus the genotype) exist at NCGRCD. (RRK, 08/2007)
