Floral. Sweet. Crispy. Carroty. Discerning eaters know that carrots don’t all taste alike.

The CIOA project is working with a rainbow of carrots to breed new varieties with with fantastic flavor and improved nutritional quality. Our project partners at University of Wisconsin–Madison got to show off some of our carrots at the Farm to Flavor event in Madison, WI, last month. Read an update on the project and the event over at Organic Seed Alliance blog here.

Check out the Spring 2019 edition of Carrot Country magazine online for a deep dive into our research.

"...CIOA's main goal is to develop orange and novel colored carrots with improved disease and nematode resistance, improved weed competitiveness, and better nutrition and flavor. That's quite the genetic package, but progress toward releasing new varieties has been efficient – and relatively quick – thanks to the project's variety trial network that expands across the U.S."

WEST LAFAYETTE, Ind. – Nationally renowned experts from the University of Wisconsin-Madison, Organic Seed Alliance, and Purdue University will present a one-day classroom and field-based workshop on organic vegetable seed production. 

Participants will learn the fundamentals needed to grow organic vegetable seed, including seed biology, harvesting, storage and how to conduct variety trials.

Hosted by Purdue Extension, the training will be held on Aug. 22 from 9 a.m. to 3 p.m. at the Daniel Turf Center, 1340 Cherry Lane, and The Student Farm, 1491 Cherry Lane, West Lafayette.

“Participating in varietal development programs and learning how to produce quality seed will ensure organic farmers have access to varieties that are best adapted to their production system, and yield produce with high nutritional quality and flavor,” said Lori Hoagland, associate professor for Purdue Horticulture and Landscape Architecture.

A tour of the The Student Farm and taste tests of advanced carrot and tomato varieties will be provided. A local chef will identify varieties that shine in the kitchen.

The workshop is sponsored by Purdue Horticulture, Carrot Improvement for Organic Agriculture (CIOA) and Tomato Organic Management and Improvement (TOMI).

Registration is $15 and includes lunch catered by The Juniper Spoon

This past week CIOA's Dr. Phil Simon led a research team to select carrot roots for seed production and breeding at his winter nursery in El Centro, CA (just north of the Mexico border). They selected roots from approximately 1,000 different populations, representing a kaleidoscope of colors and shapes for this season’s breeding efforts.
