Factors affecting development of pseudothecia produced by Venturia effusa in vitro

Nikki D. Charlton, Clive Howard Bock, Debbie L. Boykin, Carolyn A. Young

Abstract Pecan scab, caused by Venturia effusa , is the most destructive disease of pecan in the south‐eastern United States. The fungus was assumed to perpetuate solely through asexually produced conidia. Yet the identification of heterothallic mating type idiomorphs has led to …

Implications of Experimental Design on Predicting Economic Optimum Nitrogen Rates in Rice

R. L. Atwill, Larry Jason Krutz, G. Dave Spencer, Jason A. Bond et autres

Nitrogen (N) response studies in rice (Oryza sativa L.) are conducted to provide grower recommendations with economically optimum N rates (EONRs). This study was conducted to determine if experimental design alters the predicted EONR for rice. The effects of experimental design and …

Evaluation of soybean genotypes for reaction to natural field infection by Cercospora species causing purple seed stain

Shuxian Li, Gabe L. Sciumbato, Debbie L. Boykin, Grover J. Shannon et autres

Purple seed stain (PSS) of soybean (Glycine max (L.) Merr.) is a prevalent seed disease. It results in poor seed quality and reduced seed lot market grade, and thus undermines value of soybean worldwide. The objectives of this research were to evaluate …

Validation of Yield Component Traits Identified by Genome‐Wide Association Mapping in a tropical japonica × tropical japonica Rice Biparental Mapping Population

Georgia C. Eizenga, Melissa H. Jia, Aaron K. Jackson, Debbie L. Boykin et autres

The Rice Diversity Panel 1 (RDP1) was developed for genome-wide association (GWA) studies to explore five rice ( L.) subpopulations (, , , , and ). The RDP1 was evaluated for over 30 traits, including agronomic, panicle architecture, seed, and disease traits …

Approaches to quantitating the results of differentially dyed cottons

Donna V. Peralta, Devron P. Thibodeaux, Christopher D. Delhom, James E. Rodgers et autres

The differential dyeing (DD) method has been a subjective method for visually determining immature cotton fibers. We attempted to quantitate DD results and offer an efficient means of elucidating cotton maturity, without visual discretion. Image analysis of cotton color obtained with a …

Effect of charcoal rot on selected putative drought tolerant soybean genotypes and yield

Alemu Mengistu, Jeffery D. Ray, James R. Smith, Prakash R. Arelli et autres

Charcoal rot (CR), caused by the fungus Macrophomina phaseolina (Tassi) Goid. is a pervasive disease of economic significance on soybeans (Glycine max (L.) Merr.). Similarly, drought is the leading cause of yield loss in soybean worldwide. In this study, CR severity and …

Evaluation of Commercial Soybean Cultivars for Reaction to Phomopsis Seed Decay

Shuxian Li, Gabe L. Sciumbato, John Rupe, Grover J. Shannon et autres

Phomopsis seed decay (PSD), caused by Phomopsis longicolla (syn. Diaporthe longicolla), is an economically important soybean disease causing poor seed quality. Planting resistant cultivars is one of the most effective means to control PSD. In this study, 16 commercially available maturity groups …

Control of Pecan Weevil With Microbial Biopesticides

David I. Shapiro‐Ilan, Ted E. Cottrell, Clive Howard Bock, Mai Kim et autres

The pecan weevil, Curculio caryae (Horn) (Coleoptera: Curculionidae), is a key pest of pecans Carya illinoinensis ([Wangenh.] K. Koch) (Fagales: Juglandaceae). Control recommendations rely on broad spectrum chemical insecticides. Due to regulatory and environmental concerns, effective alternatives for C. caryae control must …

Yield, Fruit Quality Traits, and Leaf Nutrient Concentration of ‘Prolific’ Sapodilla Grafted onto Seedlings of 16 Sapodilla Rootstocks in Puerto Rico

Ricardo Goenaga, Héber Irizarry, David Jenkins, Debbie L. Boykin et autres

Research on sapodilla ( Manilkara zapota ) has been very limited. A field study was conducted to determine the yield potential, fruit quality traits, leaf nutrient composition, and scion/rootstock compatibility of ‘Prolific’ sapodilla grafted onto 16 sapodilla rootstock seedlings. For this purpose, …

Assessment of Five Chilling Tolerance Traits and GWAS Mapping in Rice Using the USDA Mini-Core Collection

Michael Schläppi, Aaron K. Jackson, Georgia C. Eizenga, Aiju Wang et autres

Rice (Oryza sativa L.) is often exposed to cool temperatures during spring planting in temperate climates. A better understanding of genetic pathways regulating chilling tolerance will enable breeders to develop varieties with improved tolerance during germination and young seedling stages. To dissect …
