The research and development team at Manjimup Horticultural Research Institute works closely with the horticultural industry to lift productivity, understand consumer and market drivers, encourage sustainable production systems, and manage pests and diseases.
Based in the high rainfall (average 1000 mm per year) area of Manjimup, the research and development team at the Manjimup Horticultural Research Institute work closely with the horticultural industry to lift productivity, better understand consumer and market drivers, encourage sustainable and environmentally responsible production systems, and manage pests and diseases to improve product quality, reduce waste, and meet end-user needs. The team has the capacity and expertise to deliver technical horticultural research services across the south-west agricultural region.
The Manjimup Horticultural Research Institute covers 110 hectares (ha), with 55 ha suitable for research trials. Karri loam soils on the property are representative of the high-quality soils that are unique to the Manjimup and Southern Forests region, which grows a broad range of perennial and annual fruit. Market development and export certification form a large component of the institute’s activities.

Research
Research and development at the institute is focused on the genetics and agronomy of a range of temperate fruits, annual vegetables, and specialist crops, including avocadoes, apples, grapes (wine and table), pome and stone fruit, blueberries, truffles, and hemp.
The institute hosts cereal disease evaluation trials as part of the breeding of varieties better suited to Western Australian (WA) growing conditions. The evaluation trials enable oat, barley, and wheat breeding lines to be screened for disease resistance under high disease pressure in the wet and cold Manjimup climate, away from the main WA grain growing regions. The institute also bulks up seed stocks of cereal, pasture, and legume breeding materials using irrigated plots in summer. Evaluation of annual and perennial pasture varieties is undertaken in conjunction with pasture seed companies.
