To all, for comment:

The descriptor "ploidy" should be defined as "number of chromosome sets", not as "number of chromosomes". I suggest inclusion or substitution of a descriptor called "chromosome number". This number should be expressed in a manner that expresses ploidy as well as chromosome number; For the octoploid strawberry, the chromosome number should be expressed as 2n = 8x = 56, in which the term "2n" indicates a "sporophytic" number as opposed to a "gametophytic (n) number, the term "x" denotes the number of chromosomes in a basic set (x=7 for Fragaria), and the coefficient preceding the x denotes the number of chromosome sets (i.e., the ploidy, which in this case is 8).

I apologize for sending a file earlier this week that had some errors in it. The descriptor classes (column E) of the former version were misaligned with the descriptor names. The attached file has column E deleted and has been formatted for easier use and printing. It also has a typo of NAGS switched to NPGS in the Source column. The NPGS descriptors are those described by the National Plant Germplasm System Crop Germplasm Committees and information on the descriptor classes is available on the GRIN website (For apple: http://www.ars-grin.gov/cgi-bin/npgs/html/desclist.pl?115http://www.ars-grin.gov/cgi-bin/npgs/html/desclist.pl?115 and see attached file for links) The Bioversity descriptors are available online at the Bioversity website http://www.bioversityinternational.org/Publications/pubseries.asp?ID_SERIE=13http://www.bioversityinternational.org/Publications/pubseries.asp?ID_SERIE=1... and the Eurisco descriptors are available online as well.

If other groups have descriptor sets that could be included in the excel spreadsheet, please e-mail information to me. I'd be happy to add them.

We held a meeting among folks interested in developing (or learning more about) some descriptors across Rosacaea at the ASHS meetings last week. I've attached the minutes from that meeting (thanks to Jim McFerson and Nahla Bassil for their comments), as well as some associated spreadsheets. I realize that not all members of the Rosaceae genomics community may be interested in receiving e-mail on the descriptor sets in the future. We'll continue future discussions among the lists of people listed in the minutes (attendees as well as those who couldn't make it at that meeting). Please let me know if you would like to be added to that mailing list.

General background and a future direction for deciding upon Rosaceae descriptors was discussed at the meeting last week (see attached minutes). The next step is to brainstorm sets of descriptors from the major classes of interest in breeding/research programs across Rosaceae:

1. disease, 2) quality, 3) yield, 4) abiotic stress. We ask that anyone

interested come up with 3-7 descriptors in one or more of the 4 categories that could be of interest across at least 2 genera within Rosaceae. Eventually, we'll have to scale things to make them relative within the genera (i.e. raw data for fruit weight as well as weight relative to a standard) and if you'd like to comment on possible ways to accomplish this, then please do. I'll compile a list of all the ideas we receive and then forward it to those interested being on the mailing lists. If you have any questions, please feel free to contact me (e-mail is best since I'll be on travel during much of the next month). I'd like to receive a first draft of ideas by August 10th so we can have the compiled list available for discussion at the next descriptor meeting to be held during the Portland, OR Fireblight meetings on August 13.

I look forward to hearing from you. << File: Rosaceae Descriptors for GRIN7-17-07.doc >> << File: Descriptor classes.xls >> << File: trait ontologies.xls >> << File: rosaceaedescriptorlists.xls >>
