- Abstract:
- ... Cultivated peanut, the second most economically important legume crop throughout the United States and the third most important oilseed in the world, is consistently threatened by various diseases and pests. Sclerotinia minor Jagger (S. minor), the causal agent of Sclerotinia blight, is a major threat to peanut production in the Southwestern U.S., Virginia, and North Carolina and can reduce yield ...

- Abstract:
- ... In 2001, entries from the peanut core collection, a subset of the USDA peanut germplasm collection, were planted in non-replicated plots in a field with a history of Sclerotinia blight caused by Sclerotinia minor. Variability existed among entries for reaction to Sclerotinia blight. Of the 744 entries evaluated, 11% had no disease, nearly 30% had <10% disease incidence, and only 21% had 50% diseas ...

- Abstract:
- ... The production of cultivated peanut, an important agronomic crop throughout the United States and the world, is consistently threatened by various diseases and pests. Sclerotinia minor Jagger (S. minor), the causal agent of Sclerotinia blight, is a major threat to peanut production in the Southwestern US, Virginia and North Carolina. Although information on the variability of morphological traits ...

- Abstract:
- ... Sclerotinia blight, caused by Sclerotinia minor Jagger, has become one of the major limiting factors in peanut (Arachis hypogaea L.) production. The objectives of this research were to evaluate the effects of plant spacing on disease incidence and severity of Sclerotinia blight in peanut research plots, to measure the level of apparent resistance at different seeding rates, and to determine which ...

- Abstract:
- ... Efficacy of four types of Sclerotinia minor inocula were compared for disease incidence, lesion development, and differentiating a disease response on susceptible and moderately resistant peanut genotypes. Inocula were evaluated on intact and detached peanut main stem tissue. Three inocula lacked an exogenous nutrient source, which included germinating sclerotia produced on peanut stem, 3-day-old ...

- Abstract:
- ... Agronomic traits may become adversely affected when field crops are transformed with foreign genes which confer resistance to plant pathogens. Field testing of such transformed plant lines is necessary to determine if desirable yield components have been retained through the transformation and regeneration process. Thirty-four peanut lines, thirty-two of which are transgenic containing anti-fungal ...

- Abstract:
- ... Sclerotinia minor Jagger is the causal agent of Sclerotinia blight, a highly destructive disease of peanut (Arachis hypogaea). Based on evidence that oxalic acid is involved in the pathogenicity of many Sclerotinia species, our objectives were to recover transgenic peanut plants expressing an oxalic acid-degrading oxalate oxidase and to evaluate them for increased resistance to S. minor. Transform ...

- Abstract:
- ... Peanut (Arachis hypogaea L.) is susceptible to many diseases. In the southwestern USA and other regions where peanut is grown, diseases caused by fungi are a major threat to profitable production. Transgenic peanut lines possessing fungal resistance genes offer an alternative to traditional resistance and fungicide application in managing fungal diseases. Thirty-two transgenic peanut lines contain ...
