UC's Tango mandarin touted in Smithsonian

Nearly seedless Tango (right) and its antecedent W. Murcott.
UC Riverside research that resulted in the new, seedless mandarin variety Tango was featured in a Smithsonian magazine article written by Sarah C. Rich.

The story recounts how plant geneticist Mikeal Roose used irradiation on W. Murcott budwood to induce mutations that improve the fruit.

“Farmers have long selected citrus varieties that are low-seed, that have the same kinds of chromosomal rearrangements stimulated by the same thing—there’s natural radiation around all the time and it can affect the trees at any time.”

The advantage of inducing mutations, Roose explained, rather than waiting for the sun to trigger genetic variation, is that it can be targeted toward manipulating one particular feature—a kind of rapid prototyping for agriculture. The radiation accelerates the output of new genetic compositions. Each is then cultivated, screened and tested with the hope that at least one offspring will be reliably superior to its antecedent.

'Doom the Broom' demo is scheduled Thursday in Paradise
Chico Enterprise-Record

A live fire demonstration will help illustrate the need to clear growth from around structures and to be aware of the growth of Scotch, Spanish and French broom Thursday in the parking lot at 5400 Clark Road, Paradise, Calif. Glenn Nader, UC Cooperative Extension advisor for Sutter-Yuba counties, an expert in livestock and natural resources, will talk about spraying herbicides to control the weeds.

The event will go from 10:30-11:45 a.m., rain or shine. The fire demonstration will be at 11:05 a.m.
