Value Of Horticulture Industries In Western Australia 2022-2023, Manju Radhakrishnan, Rohan Prince

Horticulture published reports

The horticulture sector in Western Australia (WA) produces high quality fruit, vegetables, nuts and amenity horticulture. Western Australians benefit from consuming this steady supply of diverse, affordable and sustainably grown fresh fruit and vegetables. Amenity horticulture, in the form of parks and gardens, adds a great richness to the quality of life in WA.

It is estimated that WA produced $1.75 billion worth of fruit, vegetables, nuts and amenity horticulture in 2022–23. The real value1 of production at the wholesale level increased by 4% when compared to the 2020 figures presented in the report, Situation analysis of horticulture in Western …

Lure Specificity, Phenology, And Damage Caused By Epiphyas Moths (Lepidoptera: Tortricidae) In Western Australian Apple Orchards, Maryam Yazdani, Elliot T. Howse, Wee Tek Tay, Helen Spafford, Rieks Van Klinken

Horticulture Research Articles

Multiple Epiphyas species inhabit southwestern Western Australia, including Light Brown Apple Moth (LBAM) Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), a globally significant, polyphagous pest. This study evaluated the efficacy and specificity of lures designed for 3 Epiphyas species: E. postvittana, Epiphyas pulla (Turner), and the undescribed Epiphyas sp. (1) (Common). Additionally, the study sought to determine the presence and distribution of Epiphyas species in 3 significant apple-growing localities. Trapping, together with partial sequencing of the mitochondrial COI gene, found LBAM to be restricted to the Perth Hills and E. pulla, to apple orchards near Manjimup and Pemberton. This geographic …

Changes In Soil Chemical Attributes, Horticultural Performance And Fruit Yield Of Peach Cultivars Following Preplant And Annual Applications Of Composted Mulch Amendments, Jeffrey Hopkins

All Theses

Southeastern peach orchards often have poor soil quality due to native soil composition, intensive farming practices and generational replanting of trees in the same locations. This study investigated using mulch amendments to improve the chemical and physical quality of soil prior to planting a new peach orchard. At the beginning of the four-year study, a single-ground municipal composted mulch was incorporated into the soil at two different rates and three cultivars of peaches, ‘Rubyprince’, ‘Julyprince’, and ‘BigRed’ were planted on berms. Thereafter, the same mulch product was annually applied to the top of the berms at two different rates to …

Effect Of Harvest Time On The Incidence Of Red Drupelet Reversion And Development Of Tetraploid Linkage Maps In Blackberry, Mitchell E. Armour

Graduate Theses and Dissertations

The cultivated eastern U.S. blackberry (Rubus L. subgenus Rubus Watson) has gone through tremendous strides in both trait improvement and market outreach at the University of Arkansas System Division of Agriculture (UA System). What began as primarily a pick-your-own local fruit found mostly in the wild, has become a commercialized year-round product in most major U.S. grocery retailers. This could not have been achieved without decades of diligent breeding efforts. Although the genetic improvement of fresh-market blackberries has advanced, there are still issues that need to be addressed. One issue is the prevalence of red drupelet reversion (RDR), a physiological …

Genetic Determinism Of Xanthomonas Arboricola Pv. Pruni (Xap) Resistance, Fruit Quality, And Phenological Traits In Peach And Incorporation Of Marker-Assisted Selection (Mas) In The University Of Arkansas Peach And Nectarine Breeding Program, Terrence James Frett

Graduate Theses and Dissertations

For over two decades the incorporation of marker-assisted selection (MAS) has been discussed as an innovative approach to increase peach breeding efficiency. Although hundreds of quantitative trait loci (QTLs) have been identified, only a few have been converted into usable MAS tools. This highlights a disconnect between genomic discoveries and practical application in breeding programs, which has delayed use of MAS.

In this dissertation, three sequential steps were performed with the objective to bridge this gap and develop breeding-relevant DNA tests for MAS of fruit bacterial spot resistance (Xap1 and Xap6), fruit quality [blush (Rf), acidity (D), and acidity and …

Propagating Jujubes, Rachelle Johnstone

Research Reports

Jujubes can be propagated by various methods such as wedge/cleft grafting, whip grafting and bark grafting as well as budding. Local propagators have better success with budding but find that wedge grafting leads to a stronger tree. Most of the latest research into propagation is in micropropagation and tissue culture however this technique is mainly used for research and breeding new cultivars and not in a commercial capacity. Grafting can be more of an art than a science. Much of the success of grafting depends on not only performing a technically correct graft but performing the graft at the proper …

The Chinese jujube (Ziziphus jujuba Mill.) is one of the most important fruit crops in China and has been commonly used as a traditional Chinese medicine and food for thousands of years. The jujube is widely grown in China with cultivation records going back more than 3000 years and can also be found in neighbouring countries. The jujube is a medium-sized tree, growing 7–10 metres high. The tree has shiny deciduous foliage and produces a fruit that is known as a drupe. The fruit varies in size depending on the cultivar, and it has a thin, dark red skin surrounding …

Selections Of The Houghton Clones Of Cabernet Sauvignon, Glynn Ward, Ian Cameron, Richard Fennessy

Bulletins 4000 -

Cabernet Sauvignon is the premium red wine grape variety grown in Western Australia. The high quality wines produced have won prestigious awards and accolades nationally and internationally. The first clonal selection of Cabernet Sauvignon in Western Australia was conducted by the Department of Agriculture at the Houghton Vineyard in the Swan Valley from 1968 to 1970. The objective was yield improvement, vine health and fruit flavour. Twenty-one high performing vines were identified from vines planted in Houghton Vineyard in the 1950s as cuttings sourced from vines planted in the 1930s. These high performing vines became known as the ‘Houghton clones’. …

Organic Apples A Production Guide, Steven Mccoy

Bulletins 4000 -

The belief among some conventional apple growers that it is not possible to reliably produce profitable yields of good quality apples under an organic system in Western Australia is being reconsidered. There are now very good examples of successful commercial organic apple orchards in many parts of the world, including WA. The organic production systems developed by these dedicated growers are showing that yields and quality are comparable to conventional systems.
