Protected Varieties Managed by the NVDMC


Tango California Tango

NVDMC holds the exclusive commercial license for the Tango in Florida. The Tango was developed at the University of California Riverside and has been planted extensively in California. The Tango is a low-seeded mandarin that has excellent internal and external color. It has good flavor. The seedy predecessor to the Tango has been grown for approx 10 years in Florida. Tango matures in the southern counties and flatwoods in late November and early December elsewhere. The harvest season has not been determined – but it is expected to be mid-January. What makes the Tango unique is that it produces a crop very early, and young trees bear high quality marketable fruit – as opposed to the lower quality fruit that is typically associated with young trees. It is expected that the Tango will have a wide production range. NVDMC has collected seed-count data and this is available from the NVDMC office. Variations in fruit quality have been observed in the field. Structured trials have not been conducted to determine the cause of the variability.

Valquarius Sweet Orange

Valquarius Sweet Orange
The Valquarius 'SF14W-62' (patent pending) is a new and distinct mid-seasonValencia  sweet orange developed by the Plant Improvement Team at the University of Florida's Citrus Research and Education Center (UF-CREC) in Lake Alfred. The Valquarius 'SF14W-62' was offered for exclusive license by Florida Foundation Seed Producers Inc. (FFSP). By way of FFSP's ITN (Invitation to Negotiate) process, New Varieties Development & Management Corp. (NVDMC) was selected as the exclusive domestic licensee.


Interested growers should contact NVDMC to request a grower agreement. Once signed, growers are eligible to place orders with a licensed citrus nursery of their choice. A one-time Tree fee royalty is paid through the nursery when the trees are delivered. 70% of royalties are channeled directly into the research program.

The Valquarius 'SF14W-62' is targeted primary for the processing industry, as it has a significantly earlier fruit maturation (4-6 weeks) than standard Valencia. The Valquarius will provide earlier blending opportunities with Hamlin or Mid-Sweet to improve flavor and color.


Valquarius 'SF14W-62' trees are upright, vigorous and have shown a tendency to alternate bearing. The trees are thornier than standard Valencia, but as the thorns are mainly on scaffold branches, and the Valquarius tends to bear more terminal fruit, the impact of the thorns is minimized. A new generation of budwood was made available in 2014 that has significantly diminished thorn count. Yield and quality data is limited. However, first generation Valquarius trees appear to be at least as productive as standard Valencia.

U.S. Early Pride Early Pride

The Early Pride Tangerine is a Fallglo mutation. The Early Pride resembles the Fallglo tangerine in all ways, except it is very low seeded. Many of the Early Pride Tangerines are completely seedless, but those that have seeds, are four or less. This fruit matures quite early in the season and would be one of the first crops harvested for many packers. The fruit trends towards the large size range.


The USDA Early Pride is available to Florida Growers and nurseries. Contact NVDMC for grower, packer or nursery agreements. Studies are being conducted to determine whether U.S. Early Pride requires an interspersed pollen source for fruit set. Conclusive data is not yet available.


The US Early Pride is soon to be trialed in Texas, Arizona.

Pollinizer and Seed Information - Sept. 2014

US Early Pride fruit and seed count data.

Fruit were conducted on 84 USEP trees using 0.125 m frames. One half of the trees were interset with 'Orlando' as the pollinizer, one half had no 'Orlando'.

The average number of fruit per frame for interset trees was 8 (+/- 1.6), the average number per frame for non-interset trees 9 (+/- 1.4), the difference between the two groups was not significantly different.

EPSeed counts averaged 4.2 (+/- 0.3) (range 3 to 6) for fruit from trees that were interset and 1.8 (+/- 0.4) (range 0 to 3) for fruit from non-interset trees. Here the between the two groups was statistically significant.


So it looks like intersetting did not improve yield, but did increase the number of seeds. Seed number was increased by pollinizer. But even in the pollinized fruit seed counts were much lower than would be seen in standard Fallglo.
