RREC Newsletter

Since 1930, the Center has housed research project leaders in the areas of plant breeding, agronomy, soil science, pathology, entomology, physiology, and economics. Some research programs began as cooperative efforts between the University of Arkansas and the USDA/ARS (e.g. rice breeding, physiology) and some remain cooperative efforts (weed science). Numerous scientists from Fayetteville have participated in Center research, and at times directed it. The following are scientists that have been housed at the Rice Research and Extension Center, Stuttgart.

VARIETAL IMPROVEMENT

Dr. Roy C. Adair (1931 – 1953), USDA Agronomist, started the rice breeding program. He developed 5 rice varieties: 'Zenith' (1936), 'Arkrose' (1942), 'Kamrose' (1943), 'Rexark' (1943) and 'Prelude' (1943). He also developed the oat varieties 'De Soto' (1942) and 'Taggart'.
 
Dr. T.H. Johnston (1953 – 1983), USDA Research Agronomist, replaced Dr. Adair and developed 11 rice varieties over the next 30 years until his retirement. These include: 'Northrose' (1962), 'Nova' (1963), 'Vegold' (1963), 'Nova 66' (1966), 'Starbonnet' (1967), 'Nortai' (1972), 'Bonnet 73' (1972), 'Nova 76' (1976), 'Mars' (1977), 'Bond' (1983), and 'Newbonnet' (1984).
 
Dr. Robert Dilday (1981 – 2000), USDA Research Geneticist, was associated with the center as head of the USDA Rice Germplasm Unit. He was instrumental in the conception and funding of the USDA/ARS Dale Bumpers National Rice Research Center.

Dr. Kent McKenzie (1981 – 1982) served briefly as the first rice breeder employed by the University of Arkansas and supported by rice farmer check-off funding before moving to Louisiana to assume a rice breeding position there.
 
Dr. Karen Ann Kuenzel Moldenhauer (1982 – Present), University of Arkansas Plant Breeder, assumed responsibility for varietal development in 1982. She has released 18 varieties, including 'Tebonnet' (1983), 'Katy' (1989), 'Millie' (1990), 'Alan' (1990), 'Orion' (1991), 'Lagrue' (1993), 'Drew' (1996), 'Wells' (1999), 'Ahrent' (2001), 'Francis' (2002), ‘Banks’ (2004), ‘Spring’ (2005), ‘CL 171AR’ (2006), ‘Taggart’ (2009), ‘Templeton’ (2009), ‘CL 142 AR’ (2009), ‘CL 181 AR’ (2009), and ‘RoyJ’ (2010).
 
Dr. Kenneth Gravois (1990 – 1997), University of Arkansas Plant Breeder, participated in the program and released the varieties 'Adair' (1993) and 'Kaybonnet' (1994).
 
Dr. James W. Gibbons (1999 – 2011), University of Arkansas Plant Breeder, assumed responsibility for developing medium-grain and semi-dwarf varieties.  While on staff at RREC, he released the long-grain variety ‘Cybonnet’ (2004) and the medium grain variety ‘Medark’ (2004).

Dr. Chris Deren (2010 – Present), University of Arkansas Plant Breeder, is engaged in the development of hybrid rice in Arkansas.  Dr. Deren is identifying male sterile lines that can be used to develop hybrids that are adapted to the Southern US.  He released ‘JES’ (2009), an aromatic long-grain variety.

Dr. Xueyan Sha (2012 – Present), University of Arkansas Plant Breeder, is engaged in leadership for the development of medium-grain and semi-dwarf rice varieties.

Dr. Greg Berger (2012 – Present), University of Arkansas Plant Breeder, is responsible for providing leadership in the development of hybrid rice in Arkansas.  Working with Mr. Zongbu Yan, they are engaged in identification and improvement of male sterile lines, selecting appropriate restorer lines, and ultimately development of improved hybrids that have high yield potential and grain quality that ensures marketability.
