The diversity of isolates of Pyrenophora teres f. teres, the causal agent of net form net blotch (NFNB), was studied using a set of 24 Australian barley varieties. Screening at the seedling and adult plant stages was used to detect and demonstrate the relative importance of resistance at both growth stages. The results showed that almost all isolates vary in virulence as expected from a sexually reproducing population and the measure of diversity is mainly limited by the number of differential v...

Understanding the genetic basis of micronutrient concentration in wheat grain may provide useful information to breed for biofortified varieties through marker assisted selection (MAS). One hundred and thirty eight doubled haploid progeny of a cross between the wheat cultivars ‘Berkut’ and ‘Krichauff’ were evaluated for 2 years at two locations on the eastern Gangetic plains of India under timely (November) sown conditions. Grains were evaluated for Zn and Fe concentrations by energy-dispersive ...

In the late 1990s, a novel Botryosphaeria-like fungal pathogen was observed causing a disease on wheat in Queensland, characterised as white grain disorder (WGD). In recent years, this disease has sporadically appeared across the eastern states of Australia. In this study, internal transcribed spacer (ITS) region sequences were used to compare these fungi to other Botryosphaeriaceae spp. to show that they should be reclassified as members of the Eutiarosporella genus. Using a small population of...

Rhynchosporium secalis can overcome a single resistance gene of barley in a relatively short period of time. Novel genes and quantitative trait locis (QTLs) are therefore vital to control scald in barley. A population of 220 double haploid lines was developed from a cross of Vlamingh and WABAR2147, where Vlamingh showed adult plant resistance (APR) and WABAR2147 showed seedling resistance to a group of isolates. The population was tested for APR to scald under natural infection in two consecutiv...

Key message A whole genome average interval mapping approach identified eight QTL associated with P. thornei resistance in a DH population from a cross between the synthetic-derived wheat Sokoll and cultivar Krichauff.

Major gene resistance to leaf scald caused by Rhynchosporium commune is readily detected in barley seedlings. Screening of barley lines in this manner has been used to identify and map the presence of several such major genes. Similar detection systems have not been possible for minor genes, detection of which has come from field evaluation of plants at later growth stages. Resistance contributed by such minor genes has often therefore been termed adult plant resistance (APR) and most barley lin...

The Gpc-B1 gene from wild emmer has been proposed as a potential mechanism for improving grain protein in bread wheat without reducing grain yield. Near-isolines with and without the Gpc-B1 gene in three Australian-adapted genetic backgrounds, Gladius, Wyalkatchem and VR1128, were compared in 14 experiments across the south and west of Australia for grain yield, grain protein content and grain weight. The donor parents of Gpc-B1 were the Canadian cultivars Burnside and Somerset. One of the 14 ex...

Key message In two Spanish barley landraces with outstanding resistance to scald, the Rrs1 Rh4 locus was fine mapped including all known markers used in previous studies and closely linked markers were developed.

Abstract The inheritance of tolerance to high temperature stress during the grain filling period was investigated via a QTL analysis based on 138 doubled haploid progeny of a cross between the wheat cultivars Berkut and Krichauff. Performance data were collected from three seasons, in each of which the material was planted both at the conventional time and a month later. A heat sensitivity index (HSI) was also used to monitor the effect of high temperature on grain yield, thousand grain weight, ...

Abstract In southeastern Australia, Fusarium crown rot, caused by Fusarium culmorum or F. pseudograminearum, is an increasingly important disease of cereals. Because in-crop control options are limited, it is important for growers to know prior to planting which fields are at risk of yield loss from crown rot. Understanding the relationships between crown rot inoculum and yield loss would assist in assessing the risk of yield loss from crown rot in fields prior to planting. Thirty-five data sets...
