“…Pea geneticists and breeders have attempted to use wild Pf for cultivar improvement, mainly for introducing disease and pest resistance alleles (Clement et al, 2009; Jha et al, 2012; Kosterin, 2016). Most wild pea accessions in germplasm banks represent random sampling, rather than systematic collections.…”

Drought Response and Genetic Diversity in Pisum fulvum, a Wild Relative of Domesticated Pea

et al. 2017

Productivity of grain crops in semi‐arid environments is often affected by drought, which is likely to increase due to predicted climate changes. Wild pea (Pisum fulvum Sibth. & Smith, Pf) accessions sampled across its ecological amplitude in Israel (350–850 mm annual precipitation) were used to assess the genetic diversity for drought responses. We hypothesized that native species evolving under Eastern Mediterranean climate carry adaptive traits to cope with drought stress. Accessions were classified according to single‐nucleotide polymorphism variation pattern and habitat ecogeographic parameters. Significant differences were found between the accession groups, but grouping in both systems did not match. Subsequently, 52 Pf accessions and three domesticated pea (P. sativum L.) genotypes were evaluated during 2 yr under well‐watered (∼580 mm) and water‐limited (∼340 mm) treatments. Total dry matter, grain yield, harvest index, and average grain weight were higher in domesticated pea than wild Pf; however several Pf accessions exhibited lower drought susceptibility indices (i.e., greater stability across environments) than domesticated genotypes. Of special interest are a number of Pf genotypes in which low susceptibility to water stress was coupled with relatively high productivity. The sampling habitats of those low susceptibility–high productivity accessions are characterized by mild (400–530 mm) annual precipitation. Further sampling and evaluation of Pf from such locations may improve our understanding of pea drought adaptation and yield physiology.

“…The same P. humile germplasm line (P665) that carries the Mycosphaerella pinodes resistance alleles was also found to be resistant to the parasitic weed broomrape ( Orobanche crenata) (Fondevilla et al 2010). Jha et al (2012) screened wild Pisum material against Mycosphaerella pinodes isolates and identified a wild accession of this species as a promising donor of resistance alleles. Carillo et al (2013) characterized the mechanisms of response to this fungal pathogen in several wild Pisum accessions compared with susceptible domesticated check varieties.…”

“…syriacum using mainly AFLP, RAPD, and SSR markers (Tar'an et al, 2003; Prioul et al, 2004; Fondevilla et al, 2008). Accession P651 utilized in this research was the most promising for resistance breeding, as it had a relatively low disease score under field, as well as greenhouse, conditions (Jha et al, 2012). Earlier, Fondevilla et al (2005) observed that P651 ( P. fulvum ) had the highest level of resistance to P. pinodes , followed by P670 ( P. sativum ssp.…”

Ascochyta blight of pea (Pisum sp.), caused by Peyronellaea pinodes, often results in serious yield losses. Some accessions of Pisum fulvum Sibth. & Sm. previously showed high levels of resistance and could be used as sources of new resistance genes. The objectives of this study were to develop a single nucleotide polymorphism (SNP)‐based linkage map and identify genomic regions associated with Ascochyta blight resistance. A population (PR‐19) consisting of 144 recombinant inbred lines (RILs) developed from a cross between P651 (P. fulvum) and Alfetta (Pisum sativum L.) was used. These RILs were evaluated for Ascochyta blight resistance under field conditions in Saskatchewan, as well as under greenhouse conditions. The RILs were genotyped using an Illumina GoldenGate array panel of 1536 SNPs. A wide range of variation was observed in Ascochyta blight scores and other agronomic traits. Disease scores were positively correlated (P < 0.001) with lodging and were negatively correlated (P < 0.001) with days to flower, plant height, days to maturity, and grain yield. A total of 733 SNP markers were assigned to six linkage groups covering 682.1 cM of the pea genome. Nine quantitative trait loci (QTLs) were identified for Ascochyta blight resistance, which individually explained 7.5 to 28% of the total phenotypic variation. In addition, five QTLs each were identified for plant height, days to maturity, and grain yield, four QTLs for days to flower, and two QTLs for lodging. The QTL abIII‐1 was consistent across locations and years, whereas abI‐IV‐2 was significant at both locations in 2014. These QTLs can be utilized for development of molecular markers associated with Ascochyta blight resistance.

Identification of Mycosphaerella Blight Resistance in Wild Pisum Species for Use in Pea Breeding

Abstract: Mycosphaerella blight caused by Mycosphaerella pinodes (Berk, and Blox.) Vestergren is the most important disease of pea (Pisum sativum L.) in the world. It reduces seed yield and quality and limits the areas where field pea can effectively be grown.
