Abstract

Understanding stability for grain yield in combination with the physiological traits would make screening for spot blotch successful in wheat, as this is presently required under the changing climatic condition.  The present study was conducted with 37 wheat genotypes from Indian Institute of Wheat & Barley Research (ICAR-IIWBR, Karnal) including two checks (Sonalika and Raj 3765) under timely sown and late sown conditions over two years (2017-18 and 2018-19) at Instructional Farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal, India.  The wheat genotypes differed significantly for all the seven morpho-reproductive traits.  The G×E interaction was found to be significant for all the traits.  In different traits different genotypes were found to be adaptable to favourable and unfavourable environments, created by the different dates of sowing over the two years. Regarding stability for grain yield the genotypes NEST-17-04 and NEST-17-37 were found to be promising for optimum yield over varying environments.
