Variety Testing
• Variety testing conducted on research stations, which are autonomous.
• Funding generated by entry fees– Wheat/oats - $300/entry (receives commodity support)– Corn/grain sorghum - $500/entry– Soybeans - $600/entry– Cotton - $900/entry– Fees are divided among coordinator, cooperators, and
administration
• RCB with 4 to 5 reps• Data posted on the web
– www.lsuagcenter.com/crop– Click on “Variety Trials & Production Practices”– Single locations

Background of OVT 1992 - 2000
- Any variety tested for three years and whose yield falls within 90% of the avg. yield of the top three hybrids by location and maturity group was recommended provided it was acceptable in other agronomic traits.
![Page 6: Louisiana Variety Testing 2010 SCC-33/UCTA St. Pete Beach, FL January 26-29, 2010 Rick Mascagni Northeast Research Station St. Joseph, LA](https://reader033.vdocument.in/reader033/viewer/2022051316/5697bf9d1a28abf838c939cc/html5/thumbnails/6.jpg)
Background of OVT2001- 2007
- Any variety tested for two years and whose yield falls within 90% of the avg. yield of the top three hybrids by location and maturity group was recommended provided it was acceptable in other agronomic traits.

– Highest-yielding varieties for two years
(varieties that fall within one LSD for
two years) were reported

Corn Hybrid Maturity
• In the 1990’s, had early maturity (106-112 days), medium maturity (113-118 days), and late-maturity (119 and greater days) categories in the OVT.
• We were relying on seed companies to categorize hybrid maturity.
• In early 2000, started using harvest moisture for categorizing hybrid maturity.

Corn Maturity - 2001
• Early Maturity 12.9 - 14.4%
• Medium Maturity 14.7 - 18.1%
• Full Season 18.9 - 19.4%
![Page 26: Louisiana Variety Testing 2010 SCC-33/UCTA St. Pete Beach, FL January 26-29, 2010 Rick Mascagni Northeast Research Station St. Joseph, LA](https://reader033.vdocument.in/reader033/viewer/2022051316/5697bf9d1a28abf838c939cc/html5/thumbnails/26.jpg)
Corn Hybrid Maturity - 2009
• Days to maturity ranged from 107 to 120.• Harvest moisture on Sharkey clay at the
NERS ranged from 14.5 to 18.1%.• High-yielding group across locns. – 2009
– 106 – 112 day maturity – 7 hybrids– 113-118 day maturity – 40 hybrids– 119 and greater day maturity – 5 hybrids
• Should we categorize hybrids based on maturity?
