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 and biochemical evaluation of rice genotypes under aerobic and anaerobic direct seeded conditions
    (CCSHAU, Hisar, 2023-01) Goyal, Alisha; Sharma, P. C.
    A total of 44 rice genotypes were evaluated in controlled and field conditions with three replications over two seasons (2020 and 2021) at ICAR - Central Soil Salinity Research Institute, Karnal to study the physiological and biochemical attributes of rice genotypes under aerobic and anaerobic direct seeded conditions for which three experiments were performed. In the 1st exp. based on germination (%), shoot length, root length, seedling length, seedling vigor index, alpha amylase activity and sucrose synthase activity, genotypes CSR 53, PS5, IR-4630-CSR11-175 and CSR 2748-4441-195 were the best performer under aerobic and anaerobic direct seeded conditions respectively. In the 2nd exp., best performing genotypes were CSR MAGIC-167, CSR 49 and CRS 56 based on gas exchange attributes, NDVI, CT, CAT, POX, APX and yield traits i.e. 1000 grain weight, spikelet fertility, total no. of tillers per plant, panicle length, biomass and grain yield under direct seeded condition. Overall, on the basis of physiological, biochemical and yield traits, two genotypes were selected for proteomic experiment in which total no. of proteins were found more in tolerant genotype CSR MAGIC-167 (1050, 1152) as compared to sensitive genotype CSR 27SM-132 (814, 794) under both DSR and non-DSR conditions respectively. Total 195 proteins were differentially expressed under DSR condition out of which 90 proteins were up-regulated and 119 proteins were down-regulated whereas in non-DSR condition, 288 proteins were differentially expressed out of which 105 proteins were up-regulated and 169 proteins were down-regulated. The KEGG pathway of DEPs revealed that a number of pathways are involved in DSR condition but none in non-DSR condition viz., methane metabolism, plant hormone signal transduction, RNA degradation, fatty acid degradation, alpha- linolenic acid metabolism etc. Further, these lines need to be evaluated in larger and multilocation trails of AICRP under DSR conditions, so that stable and best performing lines could be released as commercial varieties for direct seeded conditions.

    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.
