Yield Progress in Deltapine Conventional Varieties Grown in the Midsouth

D. L. Keim, Larry Burdett and K. R. Jones


 
ABSTRACT

Lint yield comparisons of Deltapine varieties and new lines were made from data summarized from several tests grown across several locations and years. Yield of the varieties and lines were compared on a basis of year of release (or expected release). Yield with early season varieties increased from 0.2% to 0.8% per year with new varieties over a period of 20 years. Yield of full season varieties increased from 0.2% to 1.1% per year over a period of 12 years. Fiber quality was maintained or improved as yield improvements were made.
