III. Approve minutes of the meeting held in Sacramento, CA in 2003

Tom Warkentin moved that the minutes be accepted as revised. Jim Myers seconded the motion. The motion passed.

IV. Status of Collections
Clare Coyne summarized the status of the collection and handed out a written summary (see attached). Highlights included submission of root morphology data generated by Kevin McPhee. Clare shared that she had been in contact with Noel Ellis and Mike Ambrose at the John Innes Center regarding difficulties surrounding the exchange and distribution of seed from JIC. She indicated there was a separate form (MTA) that should have been used which would allow open distribution of exchanged material. 

It was discussed to have the genetics stock seed presently in the collection be replaced with the specific seed used to characterize each line from Norm Weeden.

Clare indicated that a project to characterize the Pisum collection with molecular markers such as RAPDs and SSR markers was underway.
Tom Warkentin reported on the status of the Canadian Germplasm Collection. Alex ? has between 600 and 700 pea accessions and that a web site is available. A student from the Vavilov institute is working at Saskatoon and plans to grow appoximately 100 eastern European  germplasm lines and characterize them for phenotype and molecular markers.

Kevin McPhee added that the collection at the Vavilov Institute is in dire straits and in need of assistance to keep the collection active. Norm Weeden also mentioned that when he visited Novosibirsk during the summer of 2005 that a similar situation existed with the collection maintained there.

V. Review of Current Evaluation Proposals

Norm Weeden and Kevin McPhee reported on the status of their respective proposals and evaluations. Norm indicated experiments for gene discovery in P. sativum ssp. abyssinicum germplasm had been completed and that a manuscript was in preparation. Kevin reported the results of cold tolerance evaluations on a selected set of germplasm lines from the overall collection. Both growth chamber and field studies had been conducted. Significant variation was observed in the growth chamber experiment for survival/tolerance to freezing temperatures. Field experiments were not as severe as desired due to relatively mild conditions, but that scores for cold damage were taken rather than winter survival per se. Additional field evaluations would be conducted in 2005 and future years. 

VI. Review of Priorities

The priorties for germplasm evaluation remained the same as previously listed: 

  1. Resistance to downy mildew
  2. Resistance to bacterial blight
  3. Resistance to bean leaf roll virus (BLRV)
  4. Insect tolerance
  5. Genetic variation for rooting characteristics
  6. Quality traits and phytonutrient content
  7. Stem strength characters

A discussion followed surrounding evaluation of the collection for powdery mildew and Weidong Chen indicated that he would submit a proposal to accomplish the evaluation.

VII. Germplasm Explorations

            Brief reports of recent collections were provided by Fred Muehlbauer (Georgia, 2004) and Clare Coyne. Clare mentioned that a cooperator collected several accessions in northern Tajikistan.
            Future collections may be include Greece in 2006.
VIII. Germplasm Evaluation Proposals

Rebecca McGee reviewed the procedures for proposal submission and review. New proposals would be due on November 14, 2005.

IX. Old Business

Committee report
            Rebecca McGee reminded the committee that the CGC report needed to be completed and that two or three of the sections had been turned in. Fred Muehlbauer indicated that he would be responsible for making sure it would be done.  

X. New Business

            Membership lists were reviewed and those who desired to be official members of the committee were designated as such.
It was moved by Norm Weeden and seconded by Lyndon Porter that the current officers be retained in their current positions, i.e. Rebecca McGee as Chairman and Kevin McPhee as Secretary. The motion passed.
It was discussed that the next meeting would be held in conjunction with NAPIA in 2007 at a location to be determined. A two year cycle for the meetings was discussed and a consensus was reached that a two year cycle would be acceptable.
Maintenance of genetic stocks and key pea recombinant inbred line (RIL) populations in the germplasm collection was discussed. It was determined that key pea RIL populations would be maintained as part of the germplasm collection, but with W6 identifiers rather than PI identifiers. Norm offered to provide seed of the P.s. ssp. abyssinicum population along with the concensus population.

XI. Adjournment

Norm Weeden moved for adjournment of the meeting. Bob Arthur seconded the motion. Motion passed.
