ARS Releases Nematode, Virus Resistant Peanut Variety

May 16, 2008

The US Department of Agriculture, Agriculture Research Service (ARS) has released a new peanut variety that may help farmers in their fight against two major peanut problems. The new hybrid, Tifguard, is the first peanut variety to show resistance to both the peanut root knot nematode and tomato spotted wilt virus (TSWV). These diseases severely limit peanut yield in the US, where annual production reaches well above one million tons.

Not only did Tifguard exhibit higher resistance to TSWV in field trials, it also produced higher yields than standard check cultivars when grown in areas with little or no nematode pressure. Tifguard seeds will be available to farmers by the 2009 planting season.
