Ascochyta Blight in Chickpea: An Update

Abstract

Chickpea (Cicer arietinum L.), one of the most cultivated legumes worldwide, is crucial for the economy of several countries and a valuable source of nutrients. Yields may be severely affected by Ascochyta blight, a disease caused by the fungus Ascochyta rabiei. Molecular and pathological studies have not yet managed to establish its pathogenesis, since it is highly variable. Similarly, much remains to be elucidated about plant defense mechanisms against the pathogen. Further knowledge of these two aspects is fundamental for the development of tools and strategies to protect the crop. This review summarizes up-to-date information on the disease’s pathogenesis, symptomatology, and geographical distribution, as well as on the environmental factors that favor infection, host defense mechanisms, and resistant chickpea genotypes. It also outlines existing practices for integrated blight management.

Biotic stress alleviating strategies in chickpea

“…When symptoms spread quickly to all aerial components, such as leaves, petioles, flowers, pods, branches and stem, tissues quickly collapse and the affected organism dies. Infected pod frequently causes seed infection and infection during the pod maturation stage often result inshriveled and infected seed (Foresto et al, 2023). A.Rabiei undergoes periods in its life cycle that are both teleomorphic (sexual) and anamorphic (asexual).…”

Comparison of Different Screening Methods for Selection of Ascochyta Blight Disease on Chickpea (Cicer arietinum L.) Genotypes

“…The majority of research state that disease re sistance had a quantitative feature and was connected to many quantitative trait loci (QTL) (Tekeoglu et al, 2002;Anbessa et al, 2009). One of the methods from cultural, host plant resistance (use of resistant varieties), chemical control and biological control is used to combat the disease (Foresto et al, 2023).…”

Comparison of different screening methods for the selection of Ascochyta blight disease on chickpea (Cicer arietinum L.) genotypes

“…The vast majority of research indicates that disease resistance has a quantitative feature and depends on many quantitative trait loci (QTL) ( Tekeoglu et al., 2002 ; Anbessa et al., 2009 ). Cultural, host plant resistance (use of resistant varieties), chemical control, and biological control methods can be used to combat the disease ( Foresto et al., 2023 ). Preferring resistant cultivars is the most effective and most ecologically beneficial technique among the listed methods ( Jimenez-Diaz et al., 1993 ; Chen et al., 2004 ; Li et al., 2015 ).…”
