‘Bowman’ ( Oryza sativa L.) (Reg. No. CV‐137, PI 663863) is a semidwarf, long‐grain rice cultivar developed at the Mississippi Agricultural and Forestry Experiment Station, Delta Research and Extension Center, Stoneville, MS and officially released in March 2007. Bowman has good straw strength, which results in minimal lodging. The yield potential has proven to be high and stable. Bowman exhibited good milling and had unique cooking and processing quality because of its extra‐high amylose coupled with the Dixiebelle‐type rapid viscosity analysis profile. Bowman was tested in a total of 40 location‐year environments from 2003 to 2006. When averaged over trials, the grain yield for Bowman was 9.7 t ha −1 , while its milling yields (the ratio of whole kernel to total milled rice as g kg −1 :g kg −1 ) was 554:685. Bowman had an average apparent amylose of 24.9% and an alkali spreading value of 4. Cook type for Bowman is extra‐high amylose with a rapid viscosity analysis type of Dixiebelle. Bowman is similar to many commonly grown cultivars in the southern USA in that it is susceptible to blast disease [caused by Pyricularia grisea ( Cooke) Sacc. ] and sheath blight disease (caused by Rhizoctonia solani J.G. Kühn). Bowman should be well adapted to the growing conditions found in the southern USA.
