Abstract: Global warming is causing changes in temperature rapidly for over two decades. The increased temperature during reproductive phase of plant growth has emerged as a serious problem all over the world. The grain-filling rate of wheat, like other cereals, depends on two main sources of carbon current assimilates from photosynthesis and water soluble carbohydrates (WSCs) transported to the grain from leaves, stem and ear reserves. The present study entitled “Effect of temperature stress on proximate composition of seed in wheat” was carried out during kharif, 2016 at Central Phytotron Unit, Mahatma Phule Krishi Vidyapeeth, Rahuri. Screening of genotypes was carried out for temperature stress tolerance by three treatments, 20 °C/15 °C, 30 °C /20 °C and 35 °C /20 °C and one temperature stress tolerant genotype with one temperature stress succeptible genotype along with two check varieties were grown in field with delayed sowing dates for assessing the performance of these selected genotypes for proximate composition of wheat seed for carbohydrates, proteins, starch and moisture which was conducted during Rabi, 2017 at PGI Farm.
