The final date of the Second Conferenceand the out 1i ne of the programme. inc1udi ng selection of the rnain speakers. was agreed by the Internat i ona1 Committee but 1oca1 arrangements and finalisation of the programme were delegatedto a local sub-committee centredat the Welsh Plant Breeding Station. We wish to record our appreciationof the work done bythis localcommittee in assuming various organisational responsibilities. From the outsettherewas a firm committmentto makethe Conferenceas international as possible and every effortwas made both to provide a programmethatwouldattract participants from allpartsof the worldand to keep costs to a minimum so as to increasethe chances of potential delegatesbeing ableto attend. Alistof participantsis includedbut it is worthyof notethattwenty-three countr ies were represented. The Conferencewas organisedintoseven half-daysessions. Six of these covered differenttopics relevantto the improvement of oats and the seventhwas a visit to the Welsh PlantBreedingStationwhere laboratory and fieldwork ontheoatcrop was demonstrated.
