Mike Oliver, USA 
Individual parents, all R. occidental:
SM28-1, 28-2 – doubles.  Sometimes not all flowers are double
SM30 – “Crescent City Gold” – much yellow on all five petals, smaller flowers
SM303 – Thin stripe reddish-brown picotee.  All picotees are reddish-brown
SM502 – Good, wide picotee on mature plants.  Also known as “Humboldt Picotee”; see below.
502like – Best, deepest picotee
(SM30 X SM247)06-1, (SM30 X SM247)06-2,  First generation crosses towards producing all yellow flowers.  These are Mr. Oliver's best two plants so far.  This was the original cross done by Britt Smith done towards the all yellow flower.
HS #5 – Howard Slonecker found this.  It is a relatively large flower with yellow on all five petals, but not as much as SM30.
2406 – It has yellow on all five petals, and in the wild it had a great deal of pink.
(502like X 247)  - This plant is used as a parent partly because it has good yellow standard. Also, it is likely that Britt Smith is correct and picotee is recessive.  In that case, all progeny should have one recessive gene for picotee.
“Frank Mossman” This cross is SM232 X DD12, done by Dick Cavender.  It is large and frilly.  DD12 has been registered as “Double Dig Twelve”.
“Tatum’s Yellow Standard” This was found by Tom Tatum on Stagecoach Hill.  It has a lot of yellow on the top three petals.
Dick Cavender has registered “Crescent City Gold”, “Humboldt Picotee”, “Frank Mossman” and “Double Dig Twelve” ( DD12).
