Summary: This study screened 1,276 Pisum spp. germplasm accessions and identified low disease score pea varieties. These varieties were crossed with Australian field pea varieties to develop recombinant inbred line populations, which were then phenotyped and genotyped. Marker-trait associations were identified, and potential candidate resistance genes were found.

Summary: Ascochyta blight (AB) is a destructive disease of field peas caused by necrotrophic fungal pathogens. To identify resistant individuals, low-cost and reliable protocols for AB screening are needed. We tested and optimized three protocols to determine the best type of pathogen inoculum, host development stage, and timing of inoculation for detached-leaf assays.

Summary: This study investigated the control methods for Ascochyta blight in field peas, including the integrated use of host resistance and fungicides. The results showed that fungicide-treated plots had the slowest disease progression, while control plots had the fastest progression. Fungicide applications significantly reduced disease severity and increased yield in field peas. Economically, the combination of Othello-Top and the Burqitu variety was the most profitable management option.

Summary: This article investigates the use of STMS markers related to genes providing resistance against Ascochyta blight in the selection of resistant chickpea breeding lines. Three STMS markers (Ta2, Ts54, and Ta146) were identified as having distinguishable features for detecting Ascochyta blight resistance, and they were shown to be reliable for selecting resistant chickpea breeding lines.

Summary: Pea aphid (Acyrthosiphon pisum Harris) is the major insect pest of lentil in Morocco. The population density of pea aphid increased in early spring followed by several peaks during March-April. The number of aphids significantly correlated with maximum temperature, but negatively correlated with relative humidity and wind speed.

Summary: The accuracy of predicted breeding values (PBV) for low heritability traits can be increased by utilizing information from correlated traits. A study compared the accuracy of PBV for 10 correlated traits in a genetically diverse field pea population using univariate or multivariate linear mixed model (MLMM) analysis. The MLMM approach improved the accuracy of PBV and showed potential for increasing genetic gains in early generation selection cycles.

Summary: This study evaluated the relationship between disease development caused by P. medicaginis and production of detrimental phytoestrogens in Medicago spp. The results showed a positive correlation between the production of phytoestrogens and the incidence and severity of the disease. Based on these findings, it is possible to develop less disease-susceptible Medicago cultivars that produce fewer detrimental phytoestrogens, reducing yield loss and phytoestrogen production.

Summary: Alternaria brassicae can cause devastating disease in canola and mustard, but effective resistances are currently lacking. Screening of 150 diverse Brassicaceae varieties identified important novel resistances, including complete resistance in Camelina sativa '4076' and Diplotaxis erucoides 'Wasabi Rocket'. Other resistant varieties were also identified, such as Camelina sativa 'CSA', '4144', '405', and '3274'. These findings provide valuable resources for breeding programs to develop resistant commercial varieties and highlight the need to avoid highly susceptible varieties in both breeding and commercial settings.

Summary: The study investigates the effects of plant developmental stage, cultivar, and inoculum concentration on the development of Phoma black stem and leaf spot disease and coumestrol production in annual Medicago spp. The results show that disease incidence and severity, as well as coumestrol production, are influenced by plant developmental stage, cultivar, and inoculum level. This study highlights the importance of timely grazing of Medicago stands with lower disease and phytoestrogen levels and the need for increased vigilance at later growth stages to mitigate the risk for grazing animals.
