AgroPages-Canada: New cereal seed varieties for 2018-Agricultural news

By Leeann Minogue

You only need to take a quick look at this list to see that seed companies are responding to farmers’ needs.

Fusarium continues to be a problem across the Prairies (where there isn’t a drought). On July 13, 2017, farmers across most of Manitoba were facing a red zone on the fusarium head blight (FHB) risk map (showing an extreme risk of fusarium, based on weather conditions).

Many farmers who lived in areas where fusarium wasn’t an issue in 2017 have seen what the disease can do, and are interested in resistant seed. Fusarium-tolerant seed won’t do the whole job on its own, as is stated in the notes for FP Genetics’ new CDC Landmark VB. That seed is rated “intermediate” with respect to its resistance to FHB, but farmers who choose this seed as one part of an integrated pest management plan (including maintaining recommended rotations and spraying when necessary), should have fewer FHB problems.

Spelt varieties

SeedNet: 11Spelt11 – This variety is a high-yielding, earlier-maturing spelt with shorter straw and better lodging resistance.

Decoding VB

The wheat varieties whose names include “VB” are midge-tolerant varieties, sold as a “varietal blend” of two varieties. The main variety will make up 90 per cent of the seed and will contain the midge-tolerant gene Sm1. The other 10 per cent of the seed will be a non-midge-tolerant variety. The blending is done at the breeder stage of pedigreed seed production.

Using blended varieties creates what is called an “interspersed refuge system.” This system is designed to protect the effectiveness of the midge-tolerant gene. Most midge can’t survive the midge-tolerant wheat — the Sm1 gene causes the larvae to stop feeding and starve to death. However, in the midge population, some midge will be immune to the Sm1 gene (these are called virulent wheat midge). If every plant in the field carried the Sm1 gene, soon these virulent midge in the field would be mating with each other, creating a new population that would be immune to the Sm1 technology. Researchers say this could make the midge-tolerant wheat technology ineffective in 10 years.

Keeping some non-virulent midge in the population helps to prevent that change, drawing out the useful life of the gene. This can be done by keeping a refuge of 10 per cent non-Sm1 wheat in the field for them to eat.

Over generations, the proportion of the seed blend in the VB wheat will change. After a year with particularly high midge damage, the refuge variety could make up a much smaller percentage than 10 per cent of the seed.

To keep VB blends in check, when you buy VB wheat, you’ll need to sign a stewardship agreement and agree not to use your farm-saved seed from midge-tolerant varieties for more than one generation past certified seed.

Corn traits and the RIB

Prairie wheat growers planting new midge-tolerant seed are getting used to varietal blends, that include a variety that can act as a refuge for wheat midge that are not tolerant to the Sm1 gene.

Meanwhile, corn growers have been dealing with the concept of including refuge for years. The RIB shown in the variety description notes that the variety includes a “refuge in a bag,” meaning that the bag of corn seed includes a small amount of a second variety with different traits. Throughout the U.S., there are different refuge requirements depending on the variety you’re growing and the conditions in your area.

This list of new corn varieties includes several different corn traits. Here’s a cheat sheet.

Roundup Ready 2: glyphosate tolerant
Agrisure: glyphosate tolerant
SmartStax: glyphosate and Liberty tolerant
VT Double Pro: dual modes of action for protection against corn earworm, European corn borer and fall armyworm.

On the scale

The scale used to rate seed’s resistance to disease has five levels.
