Based in the high rainfall area of Manjimup (average 1000mm per year), 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 Manjimup Horticultural Research Institute covers 105 hectares with 55 hectares suitable for research trials. Karri loam soils on the property are representative of the high-quality soils unique to the Manjimup and Southern Forests region, which grow a broad range of perennial and annual fruit.  Market development and export certification form a large component of the Institute’s activities. The Research and Development team has the capacity and expertise to deliver technical horticultural research services across the south-west agricultural region.


Research and Development at the Institute is focussed 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, hemp and quinoa. 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 the wet conditions of Manjimup and away from the main WA grain growing regions. The Institute also bulks up seed stocks of cereal, pasture and legume breeding material using irrigated plots in summer. Evaluation of annual and perennial pasture varieties is undertaken in conjunction with pasture seed companies.
