Dr. P.C. Sharma, Director, ICAR-CSSRI, Karnal was the guest of honour in the inogural season of symposium. He stressed on the soil health aspects in relation to the influence of soil microbes on plant health. He also emphasized on the development of holistic approaches for the plant diseases management along with the need of tracking transboundary movement of pathogens. The chairman of the session, Dr. G.P. Singh, Director, ICAR- IIWBR, Karnal stressed on the integrations of efforts made by all the disciplines to make diseases management effective and profitable under changing climate scenario. He also appreciated the efforts made by organising committee for including very pertinent technical sessions on microbial diversity, pathogen variability, epidemiology, plant microbial interaction, resistance breeding and integrated plant diseases management under changing climate. At the outset, Dr. Rakesh Mehra, President, IPS (North Zone) welcomed the delegates and highlighted the relevance of the symposium and gave an overview of the programme and various deliberations made in different sessions of the symposium. Dr. Robin Gogoi, Joint Secretary, IPS, appraised the house about the activities of IPS. This session was attended by the IPS delegates, University and State Department personnel, invited scientists, teachers, students, and the corporate representatives and a total of 92 delegates across the country including North India participated in the symposium. The senior dignitaries gave the strong message for making collaborative efforts for channelizing the output of research conducted by scientists in the field of Plant Pathology to devise technology for sustainable agriculture, in view of drastic and unpredictable climate change scenario. The inaugural session was followed by nomination for Prof MJ Narishamn Academic Merit Award. In this contest, out of four contestants two students namely, Preeti Sharma and Annie Khanna were nominated to represent the zone for Prof. M.J. Narasimhan Academic Merit award competition at national level. A total three technical sessions were organised during the two day symposium. In these session, several lectures highlighting the plant disese problems of the North Zone under climate change scenario along with probable solutions were delivered by Drs. Naresh Mehta, Dr. Ashwani Basandrai, Dr. H.R. Gautam, Dr. Robin Gogoi, Dr. Kalyan K. Mondol, Dr. Sunita Chandel, Dr. Jasapl Kaur, Dr. Kushal Raj, Dr. Renu Munjal, Dr. OP Chaudhary, Dr. Rakesh Kumar, Dr. Puja Srivastava, Dr Gyandendra Singh and Dr. Vimla Singh. This two days symposium was concluded with plenary session followed by valedictory function. The function was presided by Dr. G.P. Singh, Director, ICAR-IIWBR, Karnal. Certificates to the award winners were distributed with the auspicious hands of the dignitaries on the Dias. The brief reports of each technical session were presented by Dr. Prem Lal Kashyap, organising secretary and Zonal Councillor, IPS (NZ) and following recommendations were evolved from the deliberations and discussion: • With the changing climate, some of the diseases earlier known as of minor importance are now emerging as potential threat to the field and vegetable crops. The group recommended to work on epidemiological parameters and forewarning systems to redefine management strategies and innovate new technologies. • For the integrated crop health management, cutting edge technologies (genomic, proteomics and nanotechnology) were recommended for accurate diagnosis and to monitor the changing trends in pathogenesis and the virulence spectrum in plant pathogens in climate change scenario. • It was emphasised that the emergence of new races of lentil rust, chickpea Fusarium wilt and post flowering stalk rot disease of maize are becoming serious threat for successful crop cultivation and there is an acute need for developing strategies for their successful management. • Research on the application of nanotechnology and biotechnological approaches such as gene silencing and genome editing techniques for the management of plant viruses should be intensified. • Targeting spot blotch and yellow rust diseases of wheat and barley crops by identification of durable resistance was emphasized. • To reduce the load of agrochemicals and related residue problems in field and vegetables crops, the emphasis was given on the field translation of various eco-friendly technologies based on microbial antagonists, botanicals and nanoproducts etc. • Need was felt to motivate the younger generation to take up innovative research especially in the area of deciphering plant pathogen interactions under climate change. The function concluded with the vote of thanks by Dr. Sudheer Kumar, co-organising secretary of the symposium. PROF. M.J. NARASIMHAN ACADEMIC MERIT query cover.

Breeding for disease resistance is the preferred strategy of managing both diseases. The continued emergence of new races of Pt and Pst requires a constant search for new sources of resistance. Winter wheat accessions were evaluated at seedling stage in the greenhouse with races of Pt and Pst that are predominant in the North Central US. Association mapping approach was performed on landrace accessions to identify new or underutilized sources of resistance to Pt and Pst. The majority of the accessions were susceptible to all the five races of Pt and one race of Pst. Association mapping studies identified 29 and two SNP markers associated with seedling resistance to leaf rust and stripe rust, respectively.
