Diversity Of Gibberellin 2-Oxidase Genes In The Barley Genome Offers Opportunities For Genetic Improvement, Jingye Cheng, Yong Jia, Camilla Hill, Tianhua He, Ke Wang, Ganggang Guo, Sergey Shabala, Meixue Zhou, Yong Han, Chengdao Li

Grain and Other Field Crops Research Articles

Introduction

Gibberellin (GA) is a vital phytohormone in regulating plant growth and development. During the “Green Revolution”, modification of GA-related genes created semi-dwarfing phenotype in cereal crops but adversely affected grain weight. Gibberellin 2-oxidases (GA2oxs) in barley act as key catabolic enzymes in deactivating GA, but their functions are still less known.

Objectives

This study investigates the physiological function of two HvGA2oxgenes in barley and identifies novel semi-dwarf alleles with minimum impacts on other agronomic traits.

Methods

Virus-induced gene silencing and CRISPR/Cas9 technology were used to manipulate gene expression of HvGA2ox9 and HvGA2ox8ain barley and RNA-seq …

2023 Western Australian Crop Sowing Guide, B. Shackley, B. Paynter, J. Bucat, M. Seymour, H. Dhammu

Bulletins 4000 -

Welcome to the 2023 edition of the Crop Sowing Guide for WA, which introduces 31 new variety releases: two wheat, seven barley (one as feed only and six currently under malt evaluation), 15 canola, three hay-only oat and four lentil varieties.

The Crop Sowing Guide for WA has been compiled by officers in the Department of Primary Industries and Regional Development. It provides information to support variety decisions for each of the major crops for the upcoming season.

In this edition, the canola NVT series are now identified by GRDC/NVT as ‘Low-Med Rainfall’ and ‘Med–High Rainfall’ to reflect the environments …

Fine-Mapping And Characterisation Of Genes On Barley (Hordeum Vulgare) Chromosome 2h For Salinity Stress Tolerance During Germination, Edward Mwando, Yong Han, Tefera Angessa, Xiao-Qi Zhang, Chengdao Li

Grain and Other Field Crops Research Articles

Salinity causes a detrimental impact on plant growth, particularly when the stress occurs during germination and early development stages. Barley is one of the most salt-tolerant crops; previously we mapped two quantitative trait loci (QTL) for salinity tolerance during germination on the short arm of chromosome 2H using a CM72/Gairdner doubled haploid (DH) population. Here, we narrowed down the major QTL to a region of 0.341 or 0.439 Mb containing 9 or 24 candidate genes belonging to 6 or 20 functional gene families according to barley reference genomes v1 and v3 respectively, using two DH populations of CM72/Gairdner and Skiff/CM72, …

2019 Barley Variety Sowing Guide For Western Australia, Blakely Paynter, Georgia Trainor, Jeremy Curry

Bulletins 4000 -

This bulletin is designed as a reference to help determine which barley variety to grow in your region. It provides market feedback, relative grain yield and grain quality comparisons, disease ratings, agronomic information and herbicide tolerance ratings for all malt barley varieties segregated in Western Australia (WA), those in Stage 2 of malt accreditation with Barley Australia and selected feed varieties (Tables 1 to 11; Figures 1 to 16).

The decision whether to grow barley with a malt or feed classification depends on five main factors:

(1) Premium paid for different varieties when segregated.

(2) Relative grain yield of malt …

Salt Stress Induces Non-Cg Methylation In Coding Regions Of Barley Seedlings (Hordeum Vulgare), Moumouni Konate, Michael J. Wilkinson, Benjamin T. Mayne, Stephen M. Pederson, Eileen S. Scott, Bettina Berger, Carlos M. Rodriguez Lopez

Horticulture Faculty Publications

Salinity can negatively impact crop growth and yield. Changes in DNA methylation are known to occur when plants are challenged by stress and have been associated with the regulation of stress-response genes. However, the role of DNA-methylation in moderating gene expression in response to salt stress has been relatively poorly studied among crops such as barley. Here, we assessed the extent of salt-induced alterations of DNA methylation in barley and their putative role in perturbed gene expression. Using Next Generation Sequencing, we screened the leaf and root methylomes of five divergent barley varieties grown under control and three salt concentrations, …

Early Growth Stages Salinity Stress Tolerance In Cm72 X Gairdner Doubled Haploid Barley Population, Tefera T. Angessa, Xiao-Qi Zhang, Gaofeng Zhou, Sue Broughton, Wenying Zhang, Chengdao Li

Grain and Other Field Crops Research Articles

A doubled haploid (DH) population of barley (Hordeum vulgare L.) generated from salinity tolerant genotype CM72 and salinity sensitive variety Gairdner was studied for salinity stress tolerance at germination, seedling emergence and first leaf full expansion growth stages. Germination study was conducted with deionized water, 150 mM and 300 mM NaCl treatments. Seedling stage salinity tolerance was conducted with three treatments: control, 150 mM NaCl added at seedling emergence and first leaf full expansion growth stages. Results from this study revealed transgressive phenotypic segregations for germination percentage and biomass at seedling stage. Twelve QTL were identified on chromosomes 2H–6H each …

The 2000 estimated winter wheat yield for Nebraska was a 36 bushels per acre from 1,750,000 harvested acres. The total production of winter wheat for the state was 63,000,000 bushels. This circular reports data from winter wheat trials conducted throughout Nebraska. Entries included varieties or hybrids and promising experimental strains from Nebraska and surrounding states and private breeders. This was the ninetenth year for privately developed varieties. …

Accelerating Variety Release With Double Haploids, Sue Broughton

Journal of the Department of Agriculture, Western Australia, Series 4

The use of plant tissue culture to produce special lines called doubled haploids is reducing the time taken to breed new varieties of cereal crops by up to three years. Sue Broughton outlines what doubled haploids are, how they are produced, and why they have been able to short circuit the usual lengthy breeding process.

Fast Tracking Barley Varieties Using Anther Culture, Sue Broughton, Penny Priest

Journal of the Department of Agriculture, Western Australia, Series 4

Breeding new varieties of barley or other cereal crops usually takes between 12 and 15 years. five years of that time may be needed to stabalise the new varieties so that they breed trueto type, but anther culture can reduce this delay to only eight months. This technology will allow the Department of Agriculture's barley breeding programme to respond more rapidly to changes in goals set by industry and to meet market demands.

Introducing Onslow, Western Australian Department Of Agriculture

Grain and other field crops published reports

Onslow Barley........ a new breed of barley for the southern high rainfall areas (see map VH,H4 &H5). Suited to May plantings, Onslow is the first barley developed specifically for the long growing seasons in these areas.

For the first time barley growers have a variety designed for those 4 t/ha plus yields which research shows are possible with early sowing.

Onslow is the first of a new breed of barley cultivars developed in Western Australia specifically for the southern high rainfall areas which have a long growing season.

Barley Breeding Update, P A. Portmann

Journal of the Department of Agriculture, Western Australia, Series 4

Barley production in Western Australia has increased over the past few years, peaking at 1.42 million tonnes in 1984. The European Economic Community, however, has flooded world markets for barley and over half of ourbarley was sold for feed to Saudi Arabia last year. Current prices therefore have declined as has the total area sown to barley in this State.

Despite this, the potential to increase barley yields is most promising. The Department of Agriculture has cross-bred lines in advanced stages of field testing which could increase yield by 10 per cent across the agricultural areas.

In the longer term, …
