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.

    Tissue culture studies in gladiolus (Gladiolus x grandiflorus L.) varieties
    (CCSHAU, 2010) Datta, Koushik; Rana, G.S.
    The present investigation was carried out to optimized regeneration protocol in gladiolus varieties. Corm apical bud, corm axillary bud and cormel tip explants were used for shoot regeneration on different media supplemented with different plant growth regulators. Response for shoot regeneration was observed within four weeks on all the media tested for different explants. Cormel tips and corm apical bud explants gave best shoot regeneration (55.6 and 54.4 per cent respectively) on MS medium supplemented with BAP (4.0 mg/l) and kinetin (4.0 mg/l) and the maximum number of shoot was observed on the same media. The earliest shoot regeneration response was observed on 4th day on MS media supplemented with BAP (4.0 mg/l) and kinetin (3.0 mg/l). The longest shoot was recorded from MS medium supplemented with BAP (2.5 mg/l) and kinetin (2.5, 3.5 mg/l). Maximum (54.8 per cent) rooting of shoots, longest root and earliest (on 7th day) root formation was observed on ½ MS medium supplemented with 4.0 mg/l NAA. Healthy and strong rooting was observed on all the media tested within 15 days of culturing. Survival rate of regenerated plantlets was observed to be more than 80 per cent on transplantation to pots. The best performance of cv. Amsterdam was observed in respect to shoot and root length. Fidelio perform better with respect to minimum time taken for shoot regeneration and root formation. However, the cv. Friendship performed best in respect to per cent shoot regeneration and root formation. The survival per cent is best in cv. Fidelio both after 15 and 30 days of transfer to the potting mixture.
