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.

    Seed quality assessment in naturally aged seed of fenugreek
    (CCSHAU, 2012) Bahader Singh; Dahiya, O.S.
    Seed quality plays an important role in the crop establishment and overall performance of the crop. Keeping in view, the importance of quality seed, the present research entitled “Seed quality assessment in natural aged seed of fenugreek” was carried out in the Department of Seed Science and Technology, CCS, Haryana Agricultural University, Hisar during, the year 2011-12. The experimental material for present research comprised of four genotypes of fenugreek viz. HM-202, HM-204,HM-205 and HM-214, with four seed lots of each genotype including fresh, one year, two year and three year old seed lot. In the 1 st experiment, all the four seed lots of each four genotypes were tested for various physiological and biochemical basis for loss in viability. It was observed that, test weight (g), seed density (g/cc), standard germination (%), seedling length (cm), dry weightper seedling (mg), vigour index-I & II, viability (%), speed ofemergence, seedling establishment (%) decreased whereas, mean emergence time (days) and electrical conductivity (µS/cm/seed)of seed leachates increased with ageing period. The activities of various anti-oxidant enzymes viz., dehydrogenase activity test (OD g -1 ml -1 ), catalase and peroxidase activity (mg protein -1 min -1 ) and superoxide dismutase activity (SOD) (mg protein -1 min -1 ) decreased whereas lipid peroxidase activity (MDA content) (µ mol. -1 g DW) increased with the advancement of ageing period. The seed of each genotype sustain their germination up to two year thereafter, the germinationfall below IMSCS (70 %). After ageing maximum germination wasretained by genotype HM-202 followed by, HM-205 and maximum loss of germination was observed in genotype HM-214, hence the genotype HM-202 was good storer whereas genotype HM-214 was poor storer under ambient condition. In the 2nd experiment, an effort had been made to improve the seed quality with various priming treatments (hydration (6hrs.) – dehydration, hydration (6hrs.) – dehydration + 0.25% thiram treatment and hydration with GA 3(50 ppm for 6 hrs.). The maximum enhancement in germination was observed in marginal seed lot by different priming treatments. Among various priming treatments hydration with GA 3 (50 ppm for 6 hrs.) was found superior for enhancing germination in all the four genotypes of fenugreek followed by,hydration (6hrs.) – dehydration + 0.25% Thiram treatment. Among genotypes, maximum improvement was observed in genotype HM-202 and minimum improvement in genotypeHM-204.
