  Brainboost - what is arachis oil   (Site not responding. Last check: 2007-10-21)
ARACHIS OIL is purified peanut oil is often used as a moisturiser for the skin.PEANUT OIL and ARACHIS OIL are both therefore derived from peanuts.
Because arachis oil is a purified form of peanut oil and and has less of the peanut protein in it, it is potentially less of a sensitiser.
Refined arachis oil - Also known as groundnut oil and as peanut oil, arachis oil is a clear, pale yellow, odourless oil.

  Arachis - Wikipedia, the free encyclopedia
Arachis is a genus of about 70 species of annual and perennial flowering plants in the pea family Fabaceae, native to South America.
One species, the Peanut Arachis hypogaea, is a major food crop species of global importance; some of the other species are cultivated to a small extent in South America.
Arachis species, including the peanut, are used as food plants by some Lepidoptera species including Flame Shoulder, The Nutmeg and Turnip Moth.

Stalker (1990) attempted numerical taxonomy based on morphological studies of 73 wild Arachis accessions and suggested that morphological characters can contribute much to the study of relationships between taxa and can be used as an initial step in defining systematic relationships in sections of Arachis.
Arachis stenosperma was found to possess both yellow and dark orange flowers in different seasons.
Arachis stenosperma showed the highest pod and seed length among wild species but these were less than those of many other species.

Arachis hypogaea is classified based on the presence or absence of flowers on the main axis into two subspecies, hypogaea and fastigiata.
In Arachis, SSR markers have been recently developed and proved to be useful for accession discrimination and assessment of genetic variation [19,22,23].
Transferability of SSR markers between related species is a consequence of the homology of flanking regions of the microsatellites and the size of the region between the primer pair amenable to amplification by PCR.

 Revista Brasileira de Zootecnia - Evaluation of Arachis pintoi hay using in vivo digestibility trial   (Site not responding. Last check: 2007-10-21)
A leguminosa Arachis pintoi tem apresentado bom desempenho em experimentos de avaliação agronômica em diversos países da América Latina e Austrália (Valls and Pizarro, 1994).
O alto potencial de produção animal por área em pastagens contendo Arachis pintoi é uma realidade em áreas tropicais sem seca e em áreas com períodos de três a quatro meses de seca (Lascano, 1994).
Segundo Lascano (1994), o valor nutritivo do Arachis pintoi é mais alto que a maioria das leguminosas tropicais de importância comercial,podendo ser encontrados para a folha valores de 13 a 22% de proteína bruta (PB), 60 a 67% de digestibilidade in vitro da MS (DIVMS) e 60 a 70% de digestibilidade da energia bruta.

 Resistance to Groundnut Rosette Disease in Wild Arachis Species
Out of 116 accessions of wild Arachis species evaluated, 79 accessions were scored susceptible (80 to 100% disease incidence), 12 were moderately resistant (25 to 50% disease incidence) and 25 were resistant (<10% disease incidence) to groundnut rosette disease.
Hence, exploitation of resistance to GRAV in wild Arachis species is necessary to reinforce resistance in cultivated groundnut and retard further spread of the disease from infected groundnut crops.
It is interesting to note that several of these Arachis species which are resistant to groundnut rosette (to all three components) are also resistant to early leaf spot (Cercospora arachidicola Hori.) and should be useful in breeding for multiple resistance in groundnut.

 Cover Crop - Perennial Peanut (Arachis pintoi)
Arachis accessions suited to low-fertility, high-pH coralline soils would be helpful to smallholders with cattle under coconuts in the Pacific region.
Their experience is that the perennial peanut requires extensive weed control during the first six months, if a pure stand is to be established.
After establishment, they have found that even well established plots have to be checked periodically to remove certain difficult weed species, especially vines and trailing grasses that can come in from the perimeter and can out-compete the peanut cover due to the fact that it is non-twining.

is not well charazterized for its maintenance and possible future exploitation for the improvement of cultivated peanut, Arachis hypogaea L. Our objectives were to use 2175 georeferenced observations of wild peanut (Arachis spp.) to assess the conservation status of the genus and to prioritize biologically and geographically future conservation actions.
Species distribution predictions were made on the basis of 36 climate variables, and these data were synthesized with land-use data to map the potential distribution of each species, and hence the species richness of the whole genus, excluding A. hypogaea.
