World population is growing at an alarming rate and may exceed 9.7 billion by 2050, whereas agricultural productivity has been negatively affected due to yield limiting factors such as biotic and abiotic stresses as a result of global climate change. Wheat is a staple crop for ~20% of the world population and its yield needs be augmented correspondingly in order to satisfy the demands of our increasing world population. "Green revolution", the introduction of semi-dwarf, high yielding wheat varieties along with improved agronomic management practices, gave rise to a substantial increase in wheat production and self-sufficiency in developing countries that include Mexico, India and other south Asian countries. Since the late 1980's, however, wheat yield is at a standoff with little fluctuation. The current trend is thus insufficient to meet the demands of an increasing world population. Therefore, while conventional breeding has had a great impact on wheat yield, with climatechange becoming a reality, newer molecular breeding and management tools are needed to meet the goal of improving wheat yield for the future. With the advance in our understanding of the wheat genome and more importantly, the role of environmental interactions on productivity, the idea of genomic selection has been proposed to select for multi-genic quantitative traits early in the breeding cycle. Accordingly genomic selection may remodel wheat breeding with gain that is predicted to be 3 to 5 times that of crossbreeding. Phenomics (high-throughput phenotyping) is another fairly recent advancement using contemporary sensors for wheat germplasm screening and as a selection tool. Lastly, CRISPR/Cas9 ribonucleoprotein mediated genome editing technology has been successfully utilized for efficient and specific genome editing of hexaploid bread wheat. In summary, there has been exciting progresses in the development of non-GM wheat plants resistant to biotic and abiotic stress and/or wheatwith improved nutritional quality. We believe it is important to highlight these novel research accomplishments for a broader audience, with the hope that our readers will ultimately adopt these powerful technologies for crops improvement in order to meet the demands of an expanding world population.

Dr. Gyanendra Pratap Singh is an accomplished and dedicated agricultural researcher & manager having a rich experience on multiple crops and system perspectivespanning over three decades, my overallcontribution was towards developing 48 wheat & barley varieties benefitting multitude farmers, consumers and industries including the mega varieties like HD 2967 & HD 3086 in wheat which occupies around 15 mha of area of wheat (nearly 50 % of the total area) ;46genetic stocks, developing strategies and policies aimed for agricultural development. Holding the current position of research manager for the national wheat & barley improvement programme, hehas been entrusted with the responsibility of fulfilling the programme objective of ensuring food and nutrition security to all class of people. Within hisleadership role, he has had the opportunity to plan, redefine the programme objectives and activities based on the vision 2050, ground realties and feedback of stakeholders which led the country to reach an all-time highest wheat production. Given the responsibility, a strategy document was developed to double the farmers' income by 2022 in a system perspective comprising rice-wheat-maize. He has established new research programmes and ethics in R&D, developed work plans to outperform objectives, implemented various training and capacity building programs under the MGMG scheme onthe lines of the Indian Government aiming for skilling and overall development. Having a core understanding across disciplines and department, he has developed a strong and symbiotic relationship with several national and international organisations like DST, DBT, CIMMYT and ACIAR which promotes strong research collaboration and uptake. Leadership skills, research oversight, experience and sustained interest will be my strength which will certainly contribute to the specialised need of your department towards nation building. He is also recipient of Dr. Rafi Ahmed Kidwai, Dr. BP Pal and, Dr. V S Mathur Memorial Award, BGRI Gene Stewardship Award and Nanaji Deshmuk Outstanding team award, Dr. Amrik Singh Cheema Award, AIASA Agricultural Leadership Award. He is a fellow of National Academy of Agricultural Sciences, Indian Society of Genetics and Plant Breeding, and Society for Advancement of Wheat and Barley Research; and is presently President of Society of Advancementof Wheat Research. He has guided 4 M. Sc. And 4 Ph. D. students in Indian Agricultural Research Institute. and published 188 research papers in refereed journals. He has also written 6 books on the topics of plant breeding.
