Narrative
PBR Application no: 2016/108. Description published in Plant Varieties Journal: Volume 29, Issue 3. Single Plant Selection: 'LLP-016' was derived from one of 62 genotypes from Australian and international germplasm collections screened in a replicated trial at Cleveland (QLD) in 2005 to evaluate their relative forage attributes. The breeding material that led to 'LLP-016' was originally separated on the basis of seed colour (viz. mottled brown-black vs. mid- to light brown non-mottled seeds) from the accession ILRI 13685. The brown coloured seeds from ILRI 13685 produced white-flowered, anthocyanin-free plants that bred true-to-type in subsequent generations; the mottled black-brown seeds produced predominantly purple-flowered plants with a distinctive purple anthocyanin overlay on stems, leaves and pods, but mixed in each generation with a smaller number of white-flowered anthocyanin-free plants. Based on its vigorous growth and other forage-related attributes which were comparable to, or better than, all other genotypes (including the current industry standards 'Rongai' and 'Highworth'), the original breeding material was shortlisted for further evaluation studies, which began in 2012. The heterozygous nature of the original pigmented material became apparent when it did not breed true-to-type in the subsequent generation (2013). Progeny tests over two generations (2014 and 2015) starting with 27 spaced pigmented plants (2014) confirmed normal Mendelian dominant-recessive ratios of approximately 3:1 for plant, flower and seed pigmentation, with the white flowers and anthocyanin-free characters being recessive and the purple flowers and anthocyanin-pigmented characters being dominant. Twelve homozygous purple-pigmented plants were identified and remained true-to-type in the second generation (2015). 'LLP-016' is a synthetic cultivar based on a mixture of five of these homozygous lines selected on the basis of their more prostrate spreading growth habit. 'LLP-016' been further evaluated near Tansey, Kingaroy, Gordonvale, and Walkamin (QLD). Seed increase has also been initiated at Walkamin (QLD). Breeders: Donald S. Loch & Margaret Zorin.
