The inheritance of four morphological traits in peanut (Arachis hypogaea L.)
… cytogenetics of interspecific progenies between Arachis hypogaea and wild Arachis species have provided invaluable information on the phylogenetic relationships within the genus Arachis and on the amphidiploid nature of peanut. However, the inheritance of morphological traits using interspecific …

Genotypes to Phenotypes: Genomic attributes that impact Genome-wide Associations in peanut (Arachis hypogaea. L).
Peanut and soybean are legumes (Fabaceae) grown for their highly nutritious seeds and their ability to fix nitrogen in the soil. They are both tetraploids, with two sets of ten chromosomes (2n = 2x = 20 chromosomes) – soybean having undergone a whole genome duplication some 20 million years ago, …

Leveraging genomic mapping and QTL analysis to enhance drought tolerance of cultivated peanut (Arachis hypogaea L.)
Peanut (Arachis hypogaea L.) is second major legume crop grown after soybean in the United States, and its productivity is often limited by drought stress. Drought negatively impacts the yield and quality of peanut. Drought stress in peanut causes an annual loss of approximately $520 million in the …

Detection of freeze damage in Virginia peanuts (Arachis hypogaea L.) by conductivity, tetrazolium, dipicrylamine, and visual tests
There has been controversy over the accuracy of grading peanuts for freeze damage by United States Department of Agriculture (USDA) guidelines. Several other tests for estimating freeze damage in peanuts were investigated. The conductivity test, which measures electrolyte leakage from cells, and …

Effects of kinetin on distribution and exudation of free sterols and free fatty acids in Arachis hypogaea L. 'Argentine' under axenic conditions
The effect of kinetin concentrations (10⁻⁶M and 10⁻⁴M) on distribution of free fatty acids and sterols in plant parts and root exudates of 57-day-old peanut plants grown in nutrient solutions under gnotobiotic conditions was studied. Kinetin was applied to the roots in the culture medium five days …

Control of the potato leafhopper, Empoasca fabae (Harris), and the influence of leafhopper populations on peanut yields in Virginia
New and standard pesticides applied to peanuts (Arachis hypogaea L.) in Virginia were evaluated for control of the potato leafhopper. Leafhopper populations on test plots were monitored throughout 1975 and 1976 using a 12-inch sweep net. Grade, yield, and value data were collected from all …

Relationship of environmental factors to development of Sclerotinia minor and Sclerotinia blight of peanut
… growth, infection, and colonization of peanut (Arachis hypogaea L.) tissue was optimum at 20-25 C. Ninety-five to 100% relative humidity (RH) for more than 12 hours was necessary for germination. There was no difference in infection and colonization of main stem versus lateral branch tissue but …

Effectiveness of Current Boron Application Recommendations and Practices on Peanut (Arachis hypogaea) in the Virginia - Carolina Region
Including peanut (Arachis hypogaea L.) in crop rotations is common for eastern Virginia and the Carolinas, as it thrives in the long growing season and sandy soils. Boron (B) is widely deficient, and is more prone to leeching in sandy soils. Applied B has difficulty reaching growing points as B has …
