Researchers use gene editing to develop bacterial-blight-resistant rice

danforth center logo

The Healthy Crops team, with support from the Bill & Melinda Gates Foundation, have used gene tools to develop new varieties of disease-resistant rice that U.S. and Colombian regulators have determined are equivalent to what could be accomplished with conventional breeding. Bacterial blight can reduce rice yields by up to 70%, with the heaviest losses typically experienced by smallholder rice ... Read More »

Nutrien Ag Solutions rice variety shows high yield potential, good grain quality

seed production

• By Vicky Boyd, Editor • Since acquiring Bayer’s rice breeding program in 2015, Nutrien Ag Solutions has mostly flown under the radar developing new rice cultivars for the U.S. market. That will change in 2021 with the launch of DGL-263X, a high-yielding, high-quality, long-grain inbred variety in final development and the first commercial rice cultivar under the DynaGro brand, ...

puerto rico research facility

Despite coronavirus restrictions, rice breeding programs continue albeit with a few changes. • By Vicky Boyd, Editor • In mid-March, University of Arkansas rice breeder Xueyan Sha decided only a few days before his scheduled trip to the university’s Puerto Rican winter nursery to cancel it because of the coronavirus outbreak. Although the move meant he wouldn’t be able to ... Read More »

University of Arkansas licenses 2 long-grain varieties to Erwin-Keith

RU1701084

The University of Arkansas System Division of Agriculture has licensed two commercially released rice varieties to an Arkansas seed company that will market them to growers in time for the 2021 growing season. The long-grain rice varieties, RU1701081 and RU1701084, will be available from Erwin-Keith Inc./Progeny Ag, based in Wynne. “RU1701081 has traditional long-grain cooking quality, low chalk and can ...

CRISPR gene editing could improve rice, other crops, say UC Davis researchers

rice seeds

Scientists at University of California, Davis, have used CRISPR technology to genetically engineer rice with high levels of beta-carotene, the precursor of vitamin A. The technique provides a promising strategy for genetically improving rice and other crops. The study was published today in the journal Nature Communications. Rice is a staple food crop for more than half the world’s population. ... Read More »

Researchers go back to the future in search of rice traits

collecting samples

• By Bruce Schultz • The LSU AgCenter H. Rouse Caffey Rice Research Station is collaborating with a Cornell University-based project aimed at studying the ancestors of what became the modern rice plant. Researchers hope the work will uncover useful traits from the wild lines of rice that have been lost through domestication. Three wild strains of rice from China, ... Read More »

University of Arkansas leads research group seeking heat-tolerant rice

breeding heat-tolerant rice

The University of Arkansas is leading a research group working to identify the natural genetic variations in rice that allows the plant to produce high-quality grain in an environment of rising temperatures. The consortium of four universities recently received $4.65 million from the National Science Foundation to support their work. The team is studying the genetics of more than 400 ... Read More »

UF-led study may pay off with more heat-tolerant rice

Horticulture Professor Balasubramanian Rathinasabapathi , university of florida

Rice, the most widely consumed food crop in the world, takes a beating in hot weather. To combat the high temperatures, a global group of scientists, led by a University of Florida researcher, has found the genetic basis to breed a more heat-tolerant rice cultivar. “The productivity of rice, one of the three major cereal grains feeding the world, is ...

New University of Arkansas greenhouse will aid nighttime temperature studies

new university of arkansas greenhouse

A research greenhouse formally opened Aug. 2 further aids University of Arkansas efforts to stem yield loss after milling due to high nighttime temperatures. Jay Coker, chairman of the Rice Research and Promotion Board, says the need for an advanced facility to help develop resilient rice varieties became apparent after Arkansas rice producers lost yield after milling due to high ...
