Arkansas’ Rice Breeding Webinar Video Now Available

Video Title: University of Arkansas System Division of Agriculture Rice Breeding Program

Date and Time Video Recorded: November 30, 2017, 10:00 a.m. Central Standard Time (CST)

Description: Arkansas’ Senior Rice Plant Breeder Dr. Karen Moldenhauer discussed her Rice Plant Breeding Program as well as the University of Arkansas System, Division of Agriculture’s Rice Breeding Program.

The rice breeding program in Arkansas has similar objectives to those of other U.S. crops. These include increasing production through higher yielding cultivars, conferring resistance to/tolerance of biotic and abiotic stresses via genetic resources, and improving seed quality characteristics.

Cultivar development is a team approach that involves breeders, geneticists, pathologists, entomologists, agronomists, economists, soil scientists, food scientists, weed scientists, physiologist statisticians, and extension specialists with inputs from producers, consumers, and the rice industry.

Plant breeding, broadly defined, is the art and science of improving the genetic pattern of plants in relation to their economic use.  As in so many areas of science today, there is an art to the techniques and the interpretation of data. Data comes from visual selection, agronomic measurements, and molecular information.

Plant breeders are always looking to the future because it takes at least 8 to 10 years to develop a new cultivar and get it to producers. In the words of Henry Beachell, “We need to anticipate future needs and strive for goals not easily pictured by others—farsightedness and tolerance of uncertainty are useful attributes; long-term commitment and patience are required.”

In the University of Arkansas System Division of Agriculture rice breeding program, hybrid rice is one of our future goals. We also consider improving disease resistance, earliness, and quality characteristics as intermediate goals.

Since majority of U.S. rice cultivars belong to the tropical japonica subspecies, our long-term goal is to increase the genetic diversity of these cultivars through the introduction of new germplasm from all available sources, including indica subspecies and other species, to develop a new generation of high-yielding cultivars that show resistance to/tolerance of biotic and abiotic stresses.
