New Canola Hybrids Added to Monsanto's Yield Ready® Line-Up

WINNIPEG, MANITOBA--(Marketwire - Dec. 2, 2008) - Monsanto Canada today announced that three new Roundup Ready® hybrids have been granted the Yield Ready® seal of approval. DEKALB brand 72-55 RR, Pioneer brand 45H28 and Proven® brand 9553 offer western Canadian growers some of the very best genetics available on the market. They are the standard of excellence for elite Roundup Ready canola hybrids.

Each year Monsanto tests Roundup Ready hybrids in farmer-run field scale trials. These trials are designed to evaluate new hybrids entering the marketplace and determine if they perform at a high enough level to earn the Yield Ready designation. For a hybrid to earn the Yield Ready designation the hybrid must first be entered into Monsanto Yield Ready hybrid trials. It must then perform above the level of the checks set by Monsanto in the Yield Ready hybrid trials (equal to or greater than the mean average of current Yield Ready hybrids in the 2008 Yield Ready trial sites).

"Monsanto's field-scale trials provide a reliable source of data for farmers, demonstrating hybrid performance in real life conditions," explains Todd Younghans, trait business manager for Monsanto Canada. "They are seeded and harvested by producers and sprayed and monitored by the Monsanto Technology Development group. This allows us to collect reliable and accurate data across all season zones and give growers solid information on which to make their purchasing decisions."

The majority of canola data available for farmers come from small-plot trials but some question whether small-plot trial results give farmers an accurate picture of how canola hybrids will perform on their farm, with their equipment.

Atlin and Boyd (2000) studied the relationship between small-plot and field-scale trial results and found that small-plot trials do not reliably predict field-scale results (r2 equals 0.25).(i) The true value of large plots is that they utilize farmer equipment and agronomics. Farmers utilize the correct chemistry to unlock the true potential of the herbicide system and they are able to test under a much wider range of conditions than typical small-plot trial programs. Examples of small-plot trials are Prairie Canola Variety Trials (PCVT) and Co-op trials.

"We introduced the Yield Ready designation as a way for our growers to identify elite high-yielding Roundup Ready canola hybrid options," explains Younghans. "Grower perceptions at the time we launched Yield Ready were that Roundup Ready hybrids had a significant yield disadvantage to Liberty Link® hybrids. We knew our top yielding hybrids at the time were within one to two per cent of the top Liberty Link hybrids according to grower side-by-side comparisons. At the same time, we also knew that PCVT trials are not the best at predicting actual yield performance in a grower's field."

Younghans points out that small plot trials such as PCVT and Co-op use conventional herbicides and do not allow for true system comparisons. Small plot design also creates artificial competitive effects that can distort results. "We decided to design a testing system which would not only show growers the advantages of the appropriate weed control, but also showcase realistic yields under real world growing conditions."

Over the past two years these Yield Ready hybrids have performed at or above the levels of the Liberty Link checks (5020 and 5440) in field scale trials. Based on 56 field scale trials from 2007 and 2008, these Yield Ready hybrids show a yield advantage of 1.2%(ii) over the Liberty Link checks.

"We're excited about the new additions to the Yield Ready line up for 2009," said Younghans. "The Yield Ready testing criteria require that new products must perform at or above the mean average of the current Yield Ready approved products. The performance hurdle that has been put in place continues to move upwards and this ensures any new Yield Ready approved products are truly the best in the industry. Growers can make better informed decisions and ultimately increase their yield and profit potential."
