Response to Mycosphaerella pinodes in a germplasm collection of Pisum spp

Abstract

Little resistance against MycosphaereHa pinodes is available in pea. In this work 78 accessions of Pisum were screened for resistance to M. pinodes. Fourteen accessions showed a good level of resistance in seedlings under controlled conditions, and in mature plants in the field. The highest levels of resistance were found in P. fuivum, followed by P. sativum ssp. eiatius and P. sativum ssp. syriacum. Resistance of five selected accessions was effective against different isolates of M. pinodes originating from different countries. Resistant accessions reported in this paper have been successfully hybridized with field pea cultivars.

“…abyssinicum, subsp. elatius and P. fulvum (Fondevilla et al, 2005(Fondevilla et al, , 2011Rubiales et al, 2005Rubiales et al, , 2009Barilli et al, 2009). Wild Pisum in its native range displays a typical winter habit in which plants germinate in autumn, overwinter in the vegetative state, and flower in response to increasing day-length in spring (Abbo et al, 2003;Weller et al, 2009Weller et al, , 2012.…”

Inheritance of resistance to Mycosphaerella pinodes in two wild accessions of Pisum

“…arvense) and P665 (P. sativum subsp. syriacum) (Fondevilla et al 2005) were crossed with the susceptible commercial cultivar 'Ballet' (P. sativum subsp. sativum).…”

“…Although extensive screening of pea germplasm has been conducted, only partial resistance has been identified that by itself, is inadequate to control the disease. Good levels of partial resistance have been reported in wild pea accessions (Zimmer and Sabourin 1986;Clulow et al 1991a, Wroth 1998Fondevilla et al 2005). Knowledge of the genetic factors controlling resistance to M. pinodes in these wild accessions would facilitate gene transfer to pea cultivars.…”

Disease resistance in pea (Pisum sativum L.) types for autumn sowings in Mediterranean environments - a review

“…Although extensive searches have been carried out, only moderate resistance is available in pea cultivars and this has been inadequate to control the disease (Fondevilla et al 2007b). 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.…”
