Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Physiological studies for thermo-tolerance in bread wheat genotypes
    (CCSHAU, 2019) Goyal, Alisha; Anita Kumari
    The present investigation was aimed to evaluate physiological traits for carbohydrates accumulation and mobilization and to find correlation between physiological traits and high temperature tolerance. Ten wheat genotypes viz DBW14 (Check), PBW781, PBW821, RAJ3765 (Check), RWP-2018-26, RWP-2018-30, RWP-2018-31, RWP-2018-32, WH1239 and WH730 (Check) were sown under TS and LS conditions during rabi season of 2018 - 19 at wheat research farm, Department of Genetics & Plant Breeding, CCS HAU, Hisar. The experiment was laid out in factorial RBD consisting of 6 rows of 3m length with a 20×5 cm spacing within rows & between plants, respectively. Data were recorded for various morphological traits including number of days to heading, number of days to maturity, plant height (cm), number of productive tillers per plant, spike length (cm), number of spikelets per spike, grain yield per plant (g), biological yield per plant (g), grain weight, number of grains per spike, 1000-grain weight (g), heat susceptibility index. Other studied parameters include normalized difference vegetation index, canopy temperature, transpiration rate, photosynthetic rate, stomatal conductance, chlorophyll content, cell membrane stability, free radical scavenging activity, osmotic potential, water soluble carbohydrates from different parts of stem, stem solidness, stem dry weight and grain growth rate. Out of ten genotypes, PBW821 was identified as thermo-tolerant on the basis of maximum NDVI & minimum CT at 90DAS, photosynthetic rate, transpiration rate, stomatal conductance, cell membrane stability, osmotic potential, water soluble carbohydrate, stem solidness and stem dry weight. PBW821 also showed maximum no. of spikelet/spike, no. of grains/spike, grain weight, biomass and grain yield under LS condition. Water soluble carbohydrate were found highly correlated with stem dry weight at maturity, stem solidness at 90DAS, stem dry weight at 90 DAS and biomass and stem solidness was also found highly correlated with biomass, stem dry weight at 90 DAS, grain growth rate and stem dry weight at maturity.
