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.

    Genetic and symbiotic characterization of poly-β-hydroxybutyrate production in Rhizobium and Bradyrhizobium spp. nodulating mungbean [Vigna radiata (L.) Wilczek]
    (CCSHAU, 2008) Sandeep Kumar; Yadav, A. S.
    Twenty-one WT strains of Rhizobium/Bradyrhizobium sp. (Vigna) were isolated purified and tested for their ability to form nodules on the mungbean plants. These WT strains were screened for PHB production on Beringer’s MM with Nile blue A under UV light. The two WT strains MBR 16 and MBR 25 produced high amount of PHB and these were used to isolate PHB mutants. Three types of mutants were isolated and characterized as MHt, MM and ML mutants. The MHt mutants produced highest amount of PHB, whereas ML mutants produced very low amount of PHB. The Maximum amount of PHB was found in MBR 16 MHt 1 i. e. 1.24 g/l. The antibiotic resistance pattern of parent strains and their mutants was almost same. The symbiotic effectivity of parent strains and their mutants on mugbean plants showed that the MHt mutants had higher shoot dry weight and total shoot nitrogen than the MM and ML mutants. A highly significant positive correlation was found between the amount of PHB produced and shoot dry weight and total shoot nitrogen of the munbean plants.
