Leading in Crop Variety Development
October 20, 2020
Ä¢¹½tv AgCenter is helping to feed Louisiana and the world by developing crop varieties that are highly sought-after, not only here at home, but across the globe.
Sweet potato varieties developed by the Ä¢¹½tv AgCenter dominate the farming industry in Louisiana, as well as Mississippi and Arkansas. But they also rule in Australia, where 90% of all varieties grown are Ä¢¹½tv’s, and in Guatemala, Honduras, and Costa Rica.
Ä¢¹½tv AgCenter varieties of rice and sugarcane reign supreme in Louisiana—on 70% of all fields. In the past 50 years, yields for rice, sugarcane, and sweet potatoes have doubled or tripled statewide, boosted by university innovation, and an independent study found that the Ä¢¹½tv AgCenter’s herbicide-tolerant rice technology alone contributes up to $95 million in annual management cost savings for rice producers. Clearfield rice, first released in 2002, enables farmers to kill the nuisance known as “weedy riceâ€� without harming the crop. Several Clearfield varieties are now grown throughout the world, with researchers constantly fine-tuning and responding to the needs of farmers.
Collaborations between the farming industry and Ä¢¹½tv go back more than a hundred years. “I like to tell people that it’s our job to keep the dots above the [expected yield] line,â€� said Kenneth Gravois, former Ä¢¹½tv AgCenter sugarcane breeder and now a state sugarcane specialist. “But most importantly, we don’t want the dots going way up and down and then way up again. In this way, research is an insurance policy.â€�

“The variety development at Ä¢¹½tv is the cornerstone for the Louisiana sugar industry. The $3 billion impact of that work is money that stays in our local communities and small towns where sugar is a stabilizing factor in a sometimes very volatile economy. It’s also our heritage. I like to remind people that sugar is so important there’s even a football game named in our honor and that’s the Sugar Bowl.â€�
