Arkansas Soybean Performance Tests 2003, D. G. Dombek, D. K. Ahrent, R. D. Bond, I. L. Eldridge

Arkansas Agricultural Experiment Station Research Series

Soybean cultivar performance tests are conducted each year in Arkansas by the University of Arkansas Division of Agriculture. The tests provide information to companies developing cultivars and/or marketing seed within the State and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for soybean producers.


Soybean Seed Yield And Quality Under An Ultra-Short-Season Production System, Lorena Moreno, Tetsuaki Ishibashi, Pengyin Chen, Patrick Fenn Jan 2004

Soybean Seed Yield And Quality Under An Ultra-Short-Season Production System, Lorena Moreno, Tetsuaki Ishibashi, Pengyin Chen, Patrick Fenn

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Drought is a major yield-limiting factor for soybean [Glycine max.] in the southern U.S.A. The ultra-short-season production system (USSPS), which uses maturity group (MG) 00 through I cultivars planted in April in Arkansas, may minimize severe yield reduction by drought since this system allows growers to harvest soybeans before severe drought occurs. The objective of this study was to evaluate yield potential and seed quality of Northern MG 00 through I soybean cultivars in a mid-South environment. Average yields of MG 00, 0 and I were 2954, 3585, and 3782 kg ha-1, respectively, under irrigated conditions. Average yield under dryland …

Cercospora Leaf Blight Of Soybean: Pathogen Vegetative Compatibility Groups, Population Structure, And Host Resistance, Guohong Cai

LSU Doctoral Dissertations

Nitrogen nonutilizing mutants were used to assess vegetative compatibility of 58 isolates of Cercospora kikuchii, 55 of which were isolated from soybean plants in Louisiana. Only 16 of 56 self-compatible isolates were assigned to six multi-member vegetative compatibility groups (VCGs), 01-06, with two or three isolates in each VCG. The other 40 isolates were not vegetatively compatible with any isolates other than themselves. All six multi-member VCGs contained isolates from different soybean cultivars, and three included isolates from different locations. Only one VCG included isolates both from soybean leaves and from seeds, while two and three multi-member VCGs included isolates …
