Kelly,
There are about as many numbering systems for seedlings as there are
hybridizers! Just leafing through some of Keith Keppel's catalogs I found
introductions by three hybridzers, each with a different system for
identifying their seedlings.
Keith Keppel: The seedling number of MIDNIGHT OIL was 91-174A, where 91
represents the year in which the cross was made, 174 is the number of the
cross that produced MO within that year and A means MO was the first
seedling selected from that cross (B would be the 2nd selected seedling,
and so on).
George Shoop: The seedling number of PRINCE GEORGE was 90-7-1, where 90 is
the year, 7 is the cross within that year, and 1 is the seedling number of
PG within that cross.
Joe Gatty: The seedling number of OVERJOYED was W32-1, where W was the year
code, 32 was the number of the cross and 1 the number assigned to the
seedling later named OVERJOYED.
As you can see, all three systems share some means of identifying the year
the cross was made, the number of the specific cross within the year, and
the number of the (selected) seedling within the cross as the essentials
for specifically identifying each (selected) seedling. Since seedlings are
usually not given a number unless they are selected for further observation
and testing, that means that most irises live and die without
ever being individually identified at all.
