Abstract In the Eastern Gangetic Plains (EGP) region of South Asia cropping systems are predominantly rice-based and comprise rice and non-rice crops (e.g. maize, wheat, lentil, mungbean, jute) in rotation. There are large gaps between potential crop yields and those achieved in farmers’ fields, primarily due to poor crop and soil management practices. Increasing climate variability and injudicious use of natural resources, particularly water and soil, mean that cropping systems have little resi...

Abstract This study was done with an objective to attempt to pool together in wheat, the three most important traits (spot blotch resistance, high yield and earliness) for warm humid Eastern Gangetic plains (EGP) of South Asia. A Recombinant Inbred Line (RIL) population, developed from two contrasting parents (YS#58 × YS#24) for spot blotch resistance, was tested in seven environments falling under three locations of EGP. Most of the components of variation for three traits were highly significa...
The first recorded occurrence in Asia of wheat blast caused by Magnaporthe oryzae, pathotype Triticum (synonym Pyricularia oryzae) occurred in Bangladesh in March 2016. Crop losses of up to 90% have been reported, with latesown wheat suffering particularly badly. The emergence of this disease has raised concern in neighboring countries where wheat represents a significant crop, most notably in India and Nepal. The existence of effective genetic resistance is in doubt, so for the moment the sole ...

A comprehensive germplasm evaluation study of wheat accessions conserved in the Indian National Genebank was conducted to identify sources of rust and spot blotch resistance. Genebank accessions comprising three species of wheat–Triticum aestivum, T. durum and T. dicoccum were screened sequentially at multiple disease hotspots, during the 2011–14 crop seasons, carrying only resistant accessions to the next step of evaluation. Wheat accessions which were found to be resistant in the field were th...

Summary Spot blotch disease, caused by Bipolaris sorokiniana, is an important threat to wheat, causing an annual loss of ~17%. Under epidemic conditions, these losses may be 100%, yet the molecular responses of wheat to spot blotch remain almost uncharacterized. Moreover, defense-related phytohormone signaling genes have been poorly characterized in wheat. Here, we have identified 18 central components of salicylic acid (SA), jasmonic acid (JA), ethylene (ET), and enhanced disease susceptibility...
