The dynamic challenges of peanut (Arachis hypogaea L.) farming demand a quick response from breeders to develop new cultivars, process that can be aided by the application molecular markers. With goal pyramid nematode resistance and trait for high oleic:linoleic acid (high O:L) ratio in seeds, nematode-resistant cultivar Tifguard was used as recurrent female parent O:L cultivars Georgia-02C Florida-07 were donor parents trait. 'Tifguard High O/L' generated through three rounds accelerated...
‘Florida‐07’ (Reg. No. CV‐104, PI 652938) peanut ( Arachis hypogaea L. subsp. var. ) cultivar was developed by the University of Florida, Florida Agricultural Experiment Station, North Research and Education Center near Marianna, FL. It approved for release in 2006. Florida‐07 has larger‐than‐average runner market–type seeds pods. The growth habit is prostrate, typical runner‐type cultivars. Under irrigation it matures about 140 d after planting, which places category medium‐late relative...
One objective of peanut breeders is to develop cultivars with elevated oleic acid content (>740 g kg −1 ). Testing single seeds for possible using gas chromatography (GC), but it time‐consuming and requires cutting a portion the seed which could reduce germination. Using single, intact seeds, we developed near‐infrared reflectance spectroscopy (NIR) calibration equation relating measured GC predicted by NIR. The slope regression line on NIR was 1.01 ( P > t < .0001) intercept not...
Tomato spotted wilt virus (TSWV) has the potential to cause severe yield losses in peanut (Arachis hypogaea L.), an important annual legume grown around world. The most effective approach manage disease caused by TSWV is grow resistant varieties. One of key challenges breeding for resistance develop accurate, reproducible and efficient assessment method. Accurate field-based incidence severity technically challenging time-consuming. To address this challenge, a field-based, high-throughput...
Predicting soil water status remotely is appealing due to its low cost and large-scale application. During drought, plants can disconnect from the soil, causing disequilibrium between plant potentials at pre-dawn. The impact of this on drought response recovery not well understood, potentially complicating predictions spectral reflectance. This study aimed quantify drought-induced disequilibrium, evaluate responses recovery, determine potential for predicting Two species were tested: sweet...
This article examines the sources of calcium, application rate and timings these sources, their effect on peanut growth. The purpose this is to share knowledge about calcium fertilization in peanuts among crop advisors, Extension agents, farmers.

‘TUFRunner ‘511’ ’ (Reg. No. CV‐131, PI 674432) peanut ( Arachis hypogaea L. subsp. var. ) cultivar was developed by the University of Florida, Florida Agricultural Experiment Station, North Research and Education Center (NFREC) near Marianna, FL. It tested under experimental designation UF11301 approved for release in 2013. TUFRunner is a large‐seeded, runner market‐type with prostrate growth habit medium green leaves vines. The testa seed are tan color, slightly larger than ‘Georgia‐06G’...
Spotted wilt caused by tomato spotted virus (TSWV) is one of the major peanut (Arachis hypogaea L.) diseases in southeastern United States. Occurrence, severity, and symptoms disease are highly variable from season to season, making it difficult efficiently evaluate breeding populations for resistance. Molecular markers linked resistance could overcome this problem allow selection resistant lines regardless environmental conditions. Florida-EPTM '113' a cultivar with significantly lower...
Late and early leaf spot, respectively caused by Nothopassalora personata Passalora arachidicola, are damaging diseases of peanut (Arachis hypogaea) capable defoliating canopies reducing yield. Although one these may be more predominant in a given area, both important on global scale. To assist informed management decisions quantify relationships between end-of-season defoliation yield loss, meta-analyses were conducted over 140 datasets meeting established criteria. Slopes proportion loss...
ABSTRACT The identification of molecular markers for economically significant traits should greatly improve the speed and efficiency all peanut (Arachis hypogaea L.) breeding programs. Development phenotypic evaluation recombinant inbred line (RIL) populations peanut, along with genotyping, will be essential association traits. primary objectives this research were to develop 16 structured RIL that can used by community, begin high-resolution phenotyping these populations. Crosses made using...
'FloRun '107' ' (Reg. No. CV-127, PI 663993) peanut (Arachis hypogaea L. subsp. var. hypogaea) cultivar was developed by the University of Florida, Florida Agricultural Experiment Station, North Research and Education Center near Marianna, FL. Tested under experimental designation UF08301, FloRun approved for release in 2010. is a runner market-type with prostrate growth habit medium dark green leaves vines. Seed tan color smaller than 'C-99R' 'Florida-07'. Florida-07 are derived from same...
Field experiments were conducted at Marianna, FL in 2006 and Tifton, GA 2007 to compare new peanut (Arachis hypogaea) cultivars the moderately resistant cv.

Cercosporidium personatum (Berk. & Curt.) Deighton causes late leaf spot (LLS) in peanut ( Arachis hypogaea L.), which leads to necrotic lesions, early senescence and yield losses. Detailed physiological analyses can contribute an improved understanding of peanut‐disease interactions cultivar improvement. A study was conducted evaluating two cultivars with more (York) less (Carver) quantitative resistance C. grown under fungicide‐sprayed nonsprayed conditions the field at Citra, FL over...
Tomato spotted wilt, caused by wilt tospovirus (TSWV) is a major problem in peanut (Arachis hypogaea L.) producing areas of the southeastern U.S. The integrated program used to manage relies heavily on cultivars with field resistance TSWV, and finding new sources greater levels TSWV highly desirable.

Abstract Peanut composition is influenced by several groups of factors: environmental, genetic, and their interaction. This study evaluated the relative contributions these factors using data from USDA-ARS quality testing program samples multi-state Uniform Performance Tests (UPPT). Data were subjected to restricted maximum likelihood estimation variance components reflecting main effects year, production region, location within genotype (cultivar or breeding line), kernel grade (“seed...
Field experiments were conducted at Gainesville and Marianna, FL in 2004 2005 which severity of spotted wilt, caused by Tomato wilt virus, pod yield compared six peanut (Arachis hypogaea) cultivars.
