Résumé partiel
Chickpea (Cicer arietinum L.) is the largest produced food legume in South Asia and the third largest produced food legume globally after dry beans and pea. At present, chickpea is grown in more than 50 countries and is considered to be the second most important pulse crop in the world. It covers 15% of the cultivated area and nearly contributes to 14% (7.9 million tonnes) of the world’s pulse harvest of about 58 million tonnes. Chickpea is known to be affected by a number of biotic and abiotic factors which limits its growth and yield. Dry root rot (DRR) caused by Rhizoctonia bataticola is one of the major constraint in chickpea production causing an annual loss of 10 to 20%. The pathogen is known to incite different types of diseases viz., seedling blight, root rot, stem blight, fruit rot, charcoal rot, wilt, stalk rot, seedling decay and leaf blight in different crop plants. Among the abiotic stresses, water stress is a significant yield-limiting factor in Chickpea production as 90% of the major chickpea growing areas lie under arid and semi-arid zones. The biological management of dry root rot has been attempted by many scientists in the past. According to the overall research done till date, it was found that the disease can be managed to a significant extent by use of fungicides, host plant resistance, biological means combined with other management strategies.The present study was undertaken with aim to collect, identify and purify the pathogen, isolation and characterization of agriculturally important micro-organisms and to study the effect of these microbes on plant growth and diseases management. Proteomic and genomic approaches were used to study the resistance response induced by beneficial microorganisms. Présentation et version intégrale (Shodhganga)
