Dr. Sehgal received his Ph.D. in Plant Breeding and Genetics from Punjab Agricultural University. He worked as research scientist at Kansas State University (2006-2014). Since joining SDSU in 2014 he is leading the winter wheat breeding program at SDSU. His research is focused on developing and releasing high yield winter wheat cultivars with resistance to biotic (mostly FHB, stripe, leaf, and stem rust, and WSMV) and abiotic stresses (winter hardiness and drought). In addition to research, Dr. Sehgal has also been active in teaching, student advising, and outreach for the wheat industry in South Dakota. Dr. Sehgal has published more than 30 peer-reviewed articles including Nature, PNAS, Genome Biology, Plant Physiology, New Phytologist, Genetics, BMC Genomics, BMC Plant Biology, Plant Beeding and Theoretical and Applied Genetics.
Applications of ResearchThe major objectives of the breeding program are:
1) Develop and release new superior winter wheat varieties with high yield stability, durable disease resistance, and improved end-use quality for South Dakota and Northern Great Plains.
2) Identify and genetically characterize germplasm with yield potential and quality traits, resistance to diseases and insect pests, drought, heat and winter hardiness and utilize them to enhance the productivity and resistance levels in winter wheat germplasm, thus leading to the development of improved varieties.
