NDSU Release Two Soybean Varieties

FARGO - Feb 6/04 - SNS -- The North Dakota State University (NDSU) Agricultural Experiment Station released two soybean varieties -- a transgenic soybean variety named RG405RR and a non-transgenic soybean named LaMoure.

"In order to avoid confusion, all NDSU developed transgenic soybean varieties will have a number/letter system while non-transgenic varieties will continue to use names," said Al Schneiter, NDSU Department of Plant Sciences chair, when explaining the different naming schemes used for the varieties.

In RG405RR, RG denotes Roughrider Genetics, 4 indicates the year of release, 0.5 designates relative maturity and RR signifies Roundup resistance.

RG405RR has exhibited good yield potential, according to Ted Helms, NDSU soybean breeder. It is susceptible to iron chlorosis and should not be grown in high pH soils. The protein and oil percent in RG405RR are similar to Barnes and Sargent. The new soybean variety has resistance to Phytophthora races 1 through 3.

The non-transgenic soybean, LaMoure, is a 0.7 maturity variety, according to Ted Helms, leader of the NDSU soybean breeding project. LaMoure is three days earlier than Sargent and five days later than Barnes. Averaged across 24 North Dakota sites, LaMoure yielded 3.6 bushels per acre more than Barnes and 1.5 bushels more than Sargent.

It has greater resistance to lodging and better tolerance to iron chlorosis than either Barnes or Sargent. Percent protein and percent oil in LaMoure is similar to Barnes and Sargent. LaMoure has resistance to Phytopthora races 1 through 3.
