Short straw is a desired trait in oat germplasm (Avena sativa L.). Marker-assisted selection, a key tool for achieving this objective, is limited by the presence and number of available markers. Here, we have attempted to develop markers sufficiently linked to a gene specifying short straw so that marker-assisted selection could be applied. Bulked-segregant analysis was used to identify anonymo...

The experiments were conducted at Green Acres Agronomy farm near Gainesville, Florida, on an Arredondo loamy sand, a member of the loamy, silicious, hyperthermic family of grossarenic Paleudults. The field study started in 1976 included cropping systems of oat (Avena sativa)/soybean (Glycine max L. Merr.) versus oat/grain sorghum (Sorghum bicolor L.) that were split plots of four tillage treatm...

Molecular mapping of cultivated oats was conducted to update the previous reference map constructed using a recombinant inbred (RI) population derived from Avena byzantina C. Koch cv. Kanota x Avena sativa L. cv. Ogle. In the current work, 607 new markers were scored, many on a larger set of RI lines (133 vs. 71) than previously reported. A robust, updated framework map was developed to resolve...
