Notes and observations

'Tieu' is one of the most important mandarin cultivars in Vietnam. Of 50 seeds received of RSD 1995017, 3 germinated. A nucellar seedling was identified and maintained under protection (RRUT 87). A zygotic seedling was planted in the field for maintenance. This was apparently misidentified at some point as it appears to be a sweet lime (RRUT 432). This was propagated for maintenance under protection is 01/2009 (RR Krueger, 2/28/2010).

A Vietnam-born American citizen was enchanted by this accession. She informed us the "Tieu" means black pepper and that the fruit are very aromatic, including a black pepper aroma. Additional Vietnamese-Americans and Taiwanese-Americans also pronounced it as being excellent and wonderfully aromatic. May be a candidate for clean-up for niche market. Could use some assessments of basic fruit quality parameters (RR Krueger, 2/13/2017).
