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 in wheat genotypes (Triticum aestivum L.) under terminal high temperature conditions
    (CCSHAU, 2017) Pooja; Munjal, Renu
    The present investigation was conducted to evaluate various physiological traits & identify promising wheat genotypes under terminal high temperature condition. The twenty genotypes i.e. ten tolerant (WH 730, WH 1124, WH 1021, HD 3059, DBW 90, PBW 373, Raj 3765, HD 2851, HD 2285, PBW 550) & ten heat susceptible (HD 2967, DPW 621, WH 1105, DBW 88, HD 3086, HD 2733, WH 711, WH 1080, WH 1142 & K 0307) were grown during rabi season of 2016 - 17 at Field Crop Research Area, of Wheat & Barley Section, Department of Genetics & Plant Breeding, CCS HAU, Hisar, The experiment was laid out in factorial RBD consisting of 4 rows of 3m length with a 20×5 cm spacing within rows & between plants, respectively. Terminal high temperature significantly influenced physiological, biochemical, yield & yield attributes in both heat susceptible & heat tolerant genotypes but the reduction was more pronounced in the susceptible genotypes in comparison to the tolerant ones. WH 1021 was adjudged to be most tolerant genotype due to minimum reduction in photosynthetic rate, transpiration rate, chlorophyll content & minimum increase in canopy temperature, cell membrane stability. WH 1021 also showed maximum no. of productive tiller/ m row length, biomass, grain yield, thousand grain weight & maximum harvest index. K 0307 was adjudged to be most susceptible due to maximum reduction in all physiological & biochemical trait except chlorophyll fluorescence & canopy temperature. K 0307 showed poor performance in yield & yield attributes. The tolerant genotype WH 1021 was found to be the most suitable one under terminal high temperature conditions on the basis of the overall picture of physiological, morpho-physiological & yield traits studied.
