New Bovine Barleys Edge Toward Record Yields
US - For more than a decade, a barley named "Baronesse" has reigned as the undisputed queen of feed barleys in Idaho. That's an impressive record in a state that's the nation's No. 2 producer of this golden grain.
But Baronesse's superiority is being challenged by barleys from Agricultural Research Service (ARS) scientists in Aberdeen, Idaho, and their University of Idaho colleagues, writes Marcia Wood. Regionally adapted barleys from their ongoing barley breeding program are edging ahead of Baronesse's record yields.
For example, a barley called "Lenetah" yielded more tons per acre of plump, nicely filled kernels in northern Idaho research trials than did Baronesse. Those yields led ARS plant geneticists and barley breeders Don Obert and Darrell Wesenberg (now retired) and university co-investigators to make Lenetah seed available to other researchers and plant breeders for the first time last year.
Lenetah seems best suited for rain-fed fields of northern Idaho and eastern Washington, while "Tetonia," another barley from Aberdeen, does best in irrigated farmlands of southern Idaho. Like Lenetah, Tetonia has moved ahead of Baronesse in terms of yields. Tetonia produced yields 2 to 6 percent higher than those of Baronesse in tests conducted from 2001 to 2006 in Idaho and elsewhere in the West. The research team released Tetonia in 2007.
Lenetah and Tetonia, the newest barleys from the Obert-Wesenberg team, join the series of improved barleys from these plant breeders and others at ARS' Aberdeen-based Small Grains and Potato Germplasm Research Unit.
The biggest "customers" for feed barleys, from both a literal and financial standpoint, are dairy cows and beef cattle. The grain provides proteins, carbs, and other nutrients essential for the health of the big bovines, and is a nutritious alternative to corn.
