Hybrid Selection in 2010 • Importance of hybrid selection • Key criteria • Switch to traited transgenic corn • Stacked Trait and Non-Traited Hybrid Performance • Use of On-line results – Sort feature • Seed costs & Traits
The Seven Wonders of the Corn Yield World (Dr. Fred Below, Univ. of Illinois)
Selecting Hybrids for Performance & Profits Key factors to consider • Maturity • Yield potential & stability • Stalk quality & standability • Drydown • Disease & insect resistance

Hybrid Selection in 2010Stacked Corn Hybrids • Where RW and ECB are problems Bt traits provide outstanding protection. • According to university entomologists in the absence of ECB and WCR Bt traits are unnecessary and will not increase income. • Higher yielding irrespective of pest pressure • Frequent comment several years ago – “Traited hybrids doing more for us than protecting yields”
Hybrid Selection in 2010 Stacked Corn Hybrids • Are non-traited corn hybrids a viable economic alternative to traited corns? • Non-traited corn (non-GMO) premiums • Higher traited corn seed & herbicide cost • Need to consider agronomic performance, seed costs, herbicide program, weed, insect pressure. • Short term vs. long term alternative • Limited yield data
How much does it cost for corn seed technologies?Where is the breakeven point? Cost ($/A) matrix of corn seed sold at a premium (i.e. technology fee)

Are Stacked Trait Hybrids Higher Yielding? • Variation in performance between stacked trait and non-traited hybrids is related to how different genetic backgrounds respond to insertion of specific events. • Gene insertion sometimes associated w/ differences in grain moisture, stalk lodging, and grain yield - depends on genetic background and events.
Some New Traits….. • SmartStax ™ – 2010 (Monsanto) “Refuge in a bag” • Optimum™ GAT™ trait - 2010 (Pioneer) • Glyphosate and ALS tolerance • Optimum-Acre Max ™ (Pioneer) • Drought Resistance • Enhanced Nitrogen Use Efficiency • Anthracnose Stalk Rot Resiatance
Yield Potential & StabilityLook for Consistency! • Choose hybrids with consistently high yields across locations and/or years • Don’t base decisions on “cosmetic” hybrid traits (flex or girthy ears, tillering, etc.) • Look for yield stability across environments (different climatic conditions) • Obtain data from multiple test sites – preferably over two years
Planting Different Maturities • Spread maturity selections between early, mid and full season hybrids. • Reduces damage from diseases, insects and environmental stress. • Spreads out harvest time and work load • Increases genetic diversity (also can check “variety name”) ???
