Riverside’s Citrus Heritage on Display at Grow Riverside Conference

Panelists from UC Riverside help to inform the discussion

RIVERSIDE, Calif. (www.ucr.edu) — UC Riverside is famous for its citrus breeding program, and for techniques to protect citrus from pests and disease. So it makes sense that several members of the UCR community were asked to speak at a conference in Riverside called “Grow Riverside: Citrus and Beyond” held on Wednesday, March 19 and Thursday, March 20.

Tracy Kahn, principal museum scientist and the curator of UCR’s Citrus Variety Collection, was among several UCR experts who participated in panels at Riverside’s newly renovated convention center. Other UCR people who spoke: Mark Hoddle, a specialist in invasive species; staff member and R’Garden director Fortino Morales; agricultural experiment station director: Peggy Mauk.extension specialist Milt McGiffen and graduate student John Chater; Ron Loveridge, associate professor of political science. UC Riverside was one of the conference sponsors.

Here are a few facts about citrus from Tracy Kahn.

Did you know…

1. Limes are fully mature when the rind turns yellow.  Limes are sold when slightly immature and the rind of the fruit is green to distinguish them from lemons.

2. The navel structure in the fruit of a navel orange that sometimes bulges out is actually a small fruit inside the larger fruit.

3. None of the citrus types that are commercial like lemons, lime, oranges, mandarins, grapefruit and pummelos are native to California, but originated and were domesticated in China.

4. The UCR citrus breeding program has developed over 40 different citrus cultivars since the beginning of the Citrus Experiment Station in 1907.

5. The UCR Citrus Variety Collection which is in Agricultural Operations on the UCR campus is one of the world’s most diverse living collections of Citrus and related species with over 1000 different cultivars and species.
