S ummary1 An attempt has been made to trace the history of six spore collections of the oat smuts during a 10‐year period of experimental work and to compare them in regard to stability. 12 Evidence of change was found in three collections and the modifications, with one exception, were in a negative direction. 3 At an early stage in the work, collection L 2 lost by screening the capacity to attack strigosa . 4 By monospore isolations, collection C 2 was resolved into two types, one of which had a narrower range of infection than the parent collection. 5 Collection C 4 also yielded two types, but both differed from the original collection. One was more pathogenic and the other less pathogenic than the collection as a whole. 6 Reasons are given for the view that the changes were due to heterozygous types in the collections. 7 No changes were detected in three collections. 8 One collection (L 11 ) was outstanding in the uniformity of mono‐spore and monosporidial lines in culture. 9 Experiments designed to break down the resistance to smut in certain selected oat varieties met with no success.
