“…The previous closest markers to sbm-1 were GS185 (Timmerman et al 1993) and sG05_2537 (Frew et al 2002) at 8 cM and~4 cM, respectively, and our cDNA-AFLP search yielded only one closer marker, ZG10, at 0.7 cM. Alignment of our data and the published (Frew et al 2002) maps shows the relative positions of ZG10, eIF4E/sbm-1 and G05_2537 (Fig.…”

“…5 Alignment of eIF4E and ZG10 relative to sbm-1 and selected linked reference markers on LG VI. The relationship between ZG10, sbm-1/eIF4E and G05_2537 was determined by mapping ZG10 onto the JI15 × JI399 RI family for which the marker Gsp provided an anchor for comparisons with the crosses used by Frew et al (2002). Because of the limited size of the RI family, the approximate region to which ZG10 was mapped is indicated by the filled box.…”

Identification of markers tightly linked to sbm recessive genes for resistance to Pea seed-borne mosaic virus

Two virus resistance loci on linkage groups II and VI have provided the only sources of natural resistance against Pea seed-borne mosaic virus (PSbMV, Potyviridae) in the important crop plant Pisum sativum L. A combination of parallel approaches was used to collate linked markers, particularly for sbm-1 resistance on linkage group VI. We have identified sequences derived from the genes for the eukaryotic translation initiation factors eIF4E and eIF(iso)4E as being very tightly linked to the resistance gene clusters on linkage groups VI and II, respectively. In particular, no recombinants between sbm-1 and eIF4E were found amongst 500 individuals of an F2 cross between the BC4 resistant line (JI1405) and its recurrent susceptible parent 'Scout'. In a different mapping population, the gene eIF(iso)4E was also shown to be linked to sbm-2 on linkage group II. A parallel cDNA-AFLP comparison of pairs of resistant and susceptible lines also identified an expressed tag marker just 0.7 cM from sbm-1. eIF4E and eIF(iso)4E have been associated with resistance to related viruses in other hosts. This correlation strengthens the use of our markers as valuable tools to assist in breeding multiple virus resistances into peas, and identifies potential targets for resistance gene identification in pea.

The transfer of a gene conferring resistance to scald (Rhynchosporium secalis) from Hordeum bulbosum into H. vulgare chromosome 4HS

The transfer of a gene conferring resistance to scald (Rhynchosporium secalis) from Hordeum bulbosum into H. vulgare chromosome 4HS R. Pick er ing 1 , B . R ug e-We hl i ng 2 , P . A . J oh ns t on 1 , G. Schwe izer 3 , P. Ack erm an n Abstract Scald is a serious foliar disease that infects barley (Hordeum vulgare L.) causing reduced yields and adversely affecting quality. A means to combat the disease is to breed cultivars that possess genetic resistance. However, all known resistance alleles have so far originated from within the primary genepool of barley. This reliance on H. vulgare and H. vulgare ssp. spontaneum as resistance sources may encourage virulent forms of the pathogen to become established. To broaden the genetic base of cultivated barley and provide novel resistances to many diseases we have used a species from the secondary genepool of barley, H. bulbosum, in a resistance-breeding programme. In this study we describe the development and trialling of a scald-resistant recombinant line derived from a hybrid between H. vulgare and H. bulbosum. The scald resistance is simply inherited and located on the short arm of barley chromosome 4 (4HS).

“…Specific markers linked to major genes were developed for use in breeding, especially for trypsin inhibitors in pea seeds (Page et al, 2002 ; Duc et al, 2004 ), flowering (Weller and Ortega, 2015 ), lodging resistance (Zhang et al, 2006 ) and resistance to diseases such as powdery mildew (Ghafoor and McPhee, 2012 ; Reddy et al, 2015 ), pea enation and seed borne mosaic virus (Frew et al, 2002 ; Jain et al, 2013 ), fusarium wilt (McClendon et al, 2002 ), Ascochyta blight (Jha et al, 2015 ), and rust (Barilli et al, 2010 ) (Supplementary Table 1 ). Some other resistance, flowering or seed composition genes were reviewed by Warkentin et al ( 2015 ).…”

Pea (Pisum sativum L.) is an annual cool-season legume and one of the oldest domesticated crops. Dry pea seeds contain 22–25% protein, complex starch and fiber constituents, and a rich array of vitamins, minerals, and phytochemicals which make them a valuable source for human consumption and livestock feed. Dry pea ranks third to common bean and chickpea as the most widely grown pulse in the world with more than 11 million tons produced in 2013. Pea breeding has achieved great success since the time of Mendel's experiments in the mid-1800s. However, several traits still require significant improvement for better yield stability in a larger growing area. Key breeding objectives in pea include improving biotic and abiotic stress resistance and enhancing yield components and seed quality. Taking advantage of the diversity present in the pea genepool, many mapping populations have been constructed in the last decades and efforts have been deployed to identify loci involved in the control of target traits and further introgress them into elite breeding materials. Pea now benefits from next-generation sequencing and high-throughput genotyping technologies that are paving the way for genome-wide association studies and genomic selection approaches. This review covers the significant development and deployment of genomic tools for pea breeding in recent years. Future prospects are discussed especially in light of current progress toward deciphering the pea genome.
