Origin and Breeding
Controlled pollination: in 1995, the variety ‘Glider’ was control pollinated to the
breeder’s line OX89;019-137. F2 seed of the cross was sown as populations at
Kingsford Research Centre (near Gawler, SA) in 1996 and single heads selected. The
F5 seed of these panicles was reselected in 1999 from stage 2 trials sown at Kingsford
Research Centre due to maturity differences in the population. The reselected lines
were again sown as populations over summer in 1999/2000 in the bird-proof enclosure
at the Waite Institute, Urrbrae, SA and single heads selected. SV95137-6-3 was the
third population from the sixth selection of the cross 95137. It was promoted to unreplicated
trials in winter 2000 and to replicated trials in 2002. SV95137-6-3 was
promoted to stage 4 replicated hay trials in 2003 and has remained in these trials since
that time. Selection criteria: hay yield, maturity, disease resistance. Propagation: seed.
Breeder: Dr. Pamela Zwer and Ms Sue Hoppo, SARDI Oat Breeding Program,
