Ozias-Akins Elected Fellow of The American Association for the Advancement of Science (AAAS)

Peggy Ozias-Akins was recently elected fellow of The American Association for the Advancement of Science (AAAS).

AAAS is an international non-profit organization dedicated to advancing science around the world by serving as an educator, leader, spokesperson and professional association.  In addition to organizing membership activities, AAAS publishes the journal Science, as well as many scientific newsletters, books and reports, and spearheads programs that raise the bar of understanding for science worldwide

Election as a Fellow of AAAS is an honor bestowed upon members by their peers.  Fellows are recognized for meritorious efforts to advance science or its applications.

Fellow nominations may be made by:

  • the Steering Groups of the Association’s 24 sections, or
  • any three Fellows who are current AAAS members, so long as two of the three sponsors are not affiliated with the nominee’s institution, or
  • the Chief Executive Officer.

Nominations undergo review by the Steering Groups of the Association’s sections (the Chair, Chair-Elect, Retiring Chair, Secretary, and four Members-at-Large of each section).

Each Steering Group reviews only those nominations designated for its section.  Names of Fellow nominees who are approved by the Steering Groups are presented to the AAAS Council for election.

Each nominee must receive the approval of a majority of the Steering Group members, with no more than two opposed, in order to be included in the slate of Fellow nominees that is presented to the Council for a final vote.

AAAS Fellows are elected annually by the AAAS Council for meritorious efforts to advance science or its applications. Fellows have made significant contributions in areas such as research, teaching, technology, services to professional societies,  and the communication of science to the public. The following members, presented by Section affiliation, were elected Fellows in fall 2009. AAAS congratulates them and thanks them for their service to science and technology.

Pyramiding nematode resistance and high O/L traits in elite peanut cultivars using marker assisted selection

Y. Chu, P. Ozias-Akins Department of Horticulture, The University of Georgia, Tifton Campus, GA 31793-0748, C. C. Holbrook, USDA-ARS, Tifton, GA 31793

In order to integrate nematode resistance and high oleic acid to linoleic acid ratio (high O/L) traits into elite cultivars, and in particular to derive a high O/L ‘Tifguard’, hybrid F1s from Tifguard x Georgia-02C (C1804) and Tifguard x Florida-07 (C1805) were used as male parents to cross with a number of cultivars. ‘Tifguard’ has a high level of resistance to root-knot nematode while ‘Georgia-02C’ and ‘Florida-07’ are high O/L. Molecular markers for both traits were used to identify heterozygotes among F1 progenies. A total of 150 F1 progenies were produced from the proposed crosses, and 35 F1 hybrids carrying the most ideal trait combinations were selected for further crosses using the same set of cultivars as female parents. A total of 213 potentially hybrid pods was produced. We are on track to meet the objective to produce high oleic Tifguard by June 2010. Markers were also applied to F2 populations of C1804 and C1805 to identify 45 homozygotes for both nematode resistance and high O/L so that further screening can more efficiently focus on disease resistance traits. Four peanut cultivar/germplasm lines with drought tolerance and aflatoxin resistance were crossed with Tifguard and 382 F2 plants homozygous for nematode resistance were identified among 1581 F2 plants. During the breeding project, nematode resistance markers were also used to check the purity of Tifguard from various lots. The use of molecular markers for only two traits has greatly accelerated the conversion of a nematode resistant elite line to high O/L as well as the transfer of nematode resistance to improved germplasm.
