A genetic linkage map consisting of 435 molecular markers has been constructed using a doubled-haploid mapping population derived from a cross between the Australian barley feed variety Galleon and Haruna Nijo, a Japanese barley cultivar of high malting quality. This map was used to locate the genes conferring CCN and SFNB resistance from Galleon and to locate malting and brewing quality genes from Haruna Nijo. Closely linked markers to the trait loci have been identified and are now being widely implemented in Australian breeding programs.

A genetic linkage map consisting of 211 molecular markers has been generated using a doubled-haploid population derived from a cross between the Australian barley variety Clipper and the Algerian landrace Sahara 3771. The map was used in subsequent trait mapping studies to locate the genes conferring boron tolerance and cereal cyst nematode resistance from Sahara 3371 and to map several plant type and developmental genes. Closely linked markers to the trait loci have been identified and are now being widely implemented in Australian breeding programs.

Using a population of 105 interspecific F2 hybrids derived from a cross between Agropyron mongolicum Keng and Agropyron cristatum (L.) Gaertn. ‘Fairway’ as a mapping population, a genetic linkage map of crested wheatgrass was constructed based on AFLP and RAPD molecular markers. A total of 175 markers, including 152 AFLP and 23 RAPD markers, were ordered in seven linkage groups. The map distance was 416 cM, with a mean distance of 2.47 cM between markers. The number of markers ranged from 13 to 46 in each linkage group and the length of groups ranged from 18 to 104 cM. The research found that 30 out of 175 molecular markers showed segregation distortion, accounting for 17% of all markers. This is the first genetic linkage map of crested wheatgrass. This map will facilitate gene localization, cloning, and molecular marker-assisted selection in the future.

A map for the barley doubled haploid population Amagi Nijo × WI2585 was constructed to examine manganese efficiency derived from Amagi Nijo. Manganese efficiency conferred by the previously identified locus Mel1 was validated. No other loci contributing to manganese efficiency were identified, possibly because of poor maker coverage in some regions. The map was additionally used to look for loci contributing to some aspects of malting quality. A locus on 2HL was found to be associated with malt extract, and 2 loci on 4HL and 5H, respectively, were found to be associated with diastatic power.

Barley Population

A doubled haploid population of 120 individuals was produced from the parents Chebec, an Australian 2-row barley of feed quality with resistance to the cereal cyst nematode, and Harrington, a 2-rowed, Canadian variety of premium malting quality. This paper describes 18 field and laboratory experiments conducted with the population and summarises the traits mapped and analysed. The genomic location of 25 traits and genes is described and marker–trait associations for 5 traits (malt extract, diastatic power, resistance to cereal cyst nematode, early flowering, resistance to pre-harvest sprouting) important to Australian efforts to improve malting barley varieties have been used in practical breeding programs. Detailed maps for these populations are shown in this paper, while a consensus map incorporating these maps and further experiments on the populations are described elsewhere in this issue.

A high-density genetic map of apricot (Prunus armeniaca L.) was constructed using an F1 population constructed by crossing two main Chinese cultivars ‘Chuanzhihong’ and ‘Luotuohuang’, coupled with a recently developed reduced representation library (RRL) sequencing. The average sequencing depth was 38.97 in ‘Chuanzhihong’ (female parent), 33.05 in ‘Luotuohuang’ (male parent), and 8.91 in each progeny. Based on the sequencing data, 12 451 polymorphic markers were developed and used in the construction of the genetic linkage map. The final map of apricot comprised eight linkage groups, including 1991 markers, and covered 886.25 cM of the total map length. The average distance between adjacent markers was narrowed to 0.46 cM. Gaps larger than 5 cM only accounted for <0.33%. To our knowledge, this map is the densest genetic linkage map that is currently available for apricot research. It is a valuable linkage map for quantitative trait loci (QTLs) identification of important agronomic traits. Moreover, the high marker density and well-ordered markers that this linkage map provides will be useful for molecular breeding of apricot as well. In this study, we applied this map in the QTL analysis of an important agronomic trait, pistil abortion. Several QTLs were detected and mapped respectively to the middle regions of LG5 (51.005∼59.4 cM) and LG6 (72.884∼76.562 cM), with nine SLAF markers closely linked to pistil abortion. The high-density genetic map and QTLs detected in this study will facilitate marker-assisted breeding and apricot genomic study.
