The Leucaena DNA profiling project aimed to provide a DNA profile of the new variety ‘Redlands’ (BL12) and compare it to other psyllid resistant leucaena (BL24, BL34, BL39), and two commercial cultivars Wondergraze and Cunningham.
Summary
A psyllid resistant variety has now been developed and seed has been distributed to two commercial partners, (Leucseeds Pty Ltd and Bandana Station, Carnarvon pastoral) for commercialisation and distribution. The purpose of the project reported here was to provide a DNA profile of the new psyllid variety named ‘Redlands’ (BL12) and compare it to other psyllid resistant leucaena (BL24, BL34, BL39), and two commercial cultivars Wondergraze and Cunningham. The DNA profile will assist the seed companies, MLA and UQ secure a level of protection over the new psyllid resistant leucaena. Using 426 DNA markers scored among the different leucaena lines, a dendrogram (family tree) showed that Redlands had a unique DNA profile that was distinct from other psyllid resistant breeding lines BL24, 34, 39 and from commercial leucaena cultivars Wondergraze and Cunningham.
