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.

    Studies on seed viability and vigour in pearl millet [Pennisetum glaucum (L.)R. Br]
    (CCSHAU, 2011) Ananda, H.A.; Deswal, D.P.
    Twenty genotypes of pearl millet were evaluated for seed quality by various viability, vigour tests with three replications and observations were recorded on standard germination, seedling length, seedling dry weight, seed weight, seed density, vigour index-I, Vigour Index-II, accelerated ageing test, electrical conductivity, tetrazolium test, dehydrogenase activity test, pH exudates test, field emergence index, seedling establishment and mean emergence time .Significant mean squares values showed the wide variation among the genotypes for all studied parameters. The hybrids were superior for most of the vigour and viability parameters than their parental lines. The hybrids namely HHB 216 and HHB 226 ranked at top in almost all parameters. Among ‘R’, ‘A’, and ‘B’ lines HTP 3/13, HMS 7A and HMS 37B respectively were found superior, based on majority of viability and vigour tests.on the other hand ‘A’ line ICMA 97111 and ICMA 94555 has shown lowest rank in most of parameters. All the parameters were significantly positively correlated with standard germination except seedling dry weight, seed density and pH exudates test whereas, field emergence also showed the positive correlation with all parameters except seedling dry weight and pH exudates test. The electrical conductivity was negatively correlated with standard germination and field emergence. Tetrazolium test followed by vigour index-II showed highest reliability for prediction of standard germination whereas standard germination followed by tetrazolium showed the highest reliability for prediction of field emergence. Correlation coefficient analysis and regression analysis revealed that vigour and viability parameters viz., tetrazolium test, Dehydrogenase activity test, vigour indices, electrical conductivity and accelerated ageing, can be used as reliable predictors of standard germination and field emergence in pearl millet. The tetrazolium test and electrical conductivity test should be most preferred as they are not only quick and cost effective but also easy to perform.
