“…Breeding pea varieties with resistance to M. pinodes is difficult due to (1) the availability of only partial resistance (Ali-Khan et al 1973;Ali et al 1978;Bretag 1989Bretag , 1991Clulow 1989;Clulow et al 1991;Nasir et al 1992;Xue et al 1996;Kraft et al 1998;Onfroy et al 1999;Prioul et al 2003), (2) the polygenic inheritance of the resistance (Zlamal 1984;Wroth 1999;TimmermanVaughan et al 2002) and (3) the difficulty in evaluating resistance under field conditions because of interactions with agronomic (Bretag and Brouwer 1995;Tivoli et al 1996;Wang et al 1997), agricultural and/or environmental (Bretag 1991;Xue et al 1997;Wroth and Khan 1999) factors. To date, no commercial varieties with an adequate level of resistance to M. pinodes are available.…”

The inheritance of resistance to Ascochyta blight, an economically important foliar disease of field pea ( Pisum sativum L.) worldwide, was investigated. Breeding resistant pea varieties to this disease, caused by Mycosphaerella pinodes, is difficult due to the availability of only partial resistance. We mapped and characterized quantitative trait loci (QTLs) for resistance to M. pinodes in pea. A population of 135 recombinant inbred lines (RILs), derived from the cross between DP (partially resistant) and JI296 (susceptible), was genotyped with morphological, RAPD, SSR and STS markers. A genetic map was elaborated, comprising 206 markers distributed over eight linkage groups and covering 1,061 cM. The RILs were assessed under growth chamber and field conditions at the seedling and adult plant stages, respectively. Six QTLs were detected at the seedling stage, which together explained up to 74% of the variance. Ten QTLs were identified at the adult plant stage in the field, and together these explained 56.6-67.1% of the variance, depending on the resistance criteria and the organ considered. Four QTLs were detected under both growth chamber and field conditions, suggesting they were not plant-stage dependent. Three QTLs for flowering date and three QTLs for plant height were also identified in the RIL population, some of which co-located with QTLs for resistance. The relationship between QTLs for resistance to M. pinodes, plant height and flowering date is discussed.

“…Both single genes (Rap2) and QTLs have been reported conferring resistance to Ascochyta blight [157][158][159][160][161][162][163]. An early study with very few markers per linkage group identified single genes (Rmp1, Rmp2, Rmp3 and Rmp4) for M. pinodes resistance [158]. A series of QTL studies have deepened our understanding of the quantitative inheritance of resistance to M. pinodes in pea [159][160][161][162][163].…”

Pea (Pisum sativum L.) was the original model organism used in Mendel's discovery (1866) of the laws of inheritance, making it the foundation of modern plant genetics. However, subsequent progress in pea genomics has lagged behind many other plant species. Although the size and repetitive nature of the pea genome has so far restricted its sequencing, comprehensive genomic and post genomic resources already exist. These include BAC libraries, several types of molecular marker sets, both transcriptome and proteome datasets and mutant populations for reverse genetics. The availability of the full genome sequences of three legume species has offered significant opportunities for genome wide comparison revealing synteny and co-linearity to pea. A combination of a candidate gene and colinearity approach has successfully led to the identification of genes underlying agronomically important traits including virus resistances and plant architecture. Some of this knowledge has already been applied to marker assisted selection (MAS) programs, increasing precision and shortening the breeding cycle. Yet, complete translation of marker discovery to pea breeding is still to be achieved. Molecular analysis of pea collections has shown that although substantial variation is present within the cultivated genepool, wild material offers the possibility to incorporate novel traits that may have been inadvertently eliminated. Association mapping analysis of diverse pea germplasm promises to identify genetic variation related to desirable agronomic traits, which are historically difficult to breed for in a traditional manner. The availability of high throughput 'omics' methodologies offers great promise for the development of novel, highly accurate selective breeding tools for improved pea genotypes that are sustainable under current and future climates and farming systems.

“…Higher levels of resistance have been identified in wild species of Pisum (Wroth 1999;Fondevilla et al 2005), but they have not been used efficiently in breeding programmes yet. Four major genes were described (Clulow et al 1991) that have not however been verified by any other ulterior study. In contrast, QTL mapping studies have resulted in the identification of numerous genomic regions involved in the control of resistance, confirming the polygenic nature of resistance.…”

Abstract:Pea is an important grain legume mainly grown as spring crop in temperate regions. However, in areas with mild winters and dry springs, like Mediterranean type environments, spring pea types are autumn sown. Unfortunately, little efforts have been made so far in pea breeding for constraints typical of these environments, such as crenate broomrape (Orobanche crenata), rust (Uromyces pisi), powdery mildew (Erysiphe pisi) and ascochyta blight (Mycosphaerella pinodes). In this paper we revise the present state of the art in pea breeding against these diseases and we will critically discuss present progress and future perspectives.
