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.

    Effect of seed priming on viability and vigour of cowpea (Vigna unguiculata L. Walp) seed
    (CCSHAU, 2007) Maniktahla, Saurabh; Verma, S.S.
    In the present investigation, two seed lots of four varieties viz., HC2-85, HC3-8, HC98-64 and FS-68 were taken and grouped into two seed lots on the basis of germination percentage. The lot which showed germination percentage above the Indian Minimum Seed Certification Standard (75.0 per cent) of cowpea were termed as good seed lot (L1) and which showed germination percentage below the Indian Minimum Seed Certification Standard of cowpea were termed as marginal seed lot (L2). All the eight seed lots were given the five pre-sowing seed treatments viz., hydration-dehydration (for 4 h), GA3 (50ppm), GA3 (100ppm), KNO3 (0.1%) and hydration-dehydration + thiram @ 3g/kg seed treatments and compared with control. The results revealed that marginal seed lot (L2) showed more improvement than good seed lot (L1) after pre-sowing seed treatments under laboratory and field conditions. Among the varieties, HC3-8 showed maximum improvement in standard germination while HC2-85 showed maximum improvement in seedling establishment. The results also predicted that the treatment GA3 (100 ppm) followed by hydration dehydration + thiram @ 3g/kg seed was found most effective in all the parameters except in root length in which hydration dehydration + thiram @ 3g/kg seed was found most effective among all the treatments.

    Studies on seed storability in groundnut (Arachis hypogaea L.)
    (CCSHAU, 2007) Jha, Kailash Kumar; Kharb, R.P.S.
    Seeds of two groundnut cultivars MH-4 and MH-34 were dried to about 5% moisture content and stored with or without shells under ambient as well as controlled conditions in gunny bags and polythene bags to determine their effect on storage potential of seed samples. Germination was recorded quarterly and it did not differ among seed samples stored for upto 6 months, but afterwards both germination and vigour index exhibited significant reduction, irrespective of the storage environment and packaging material. At the end of storage period (12 months), the reduction in the values of germination ranged from 19.5-39.6 per cent among different combinations of storage factors. Samples stored in polythene bags and controlled conditions maintained the minimum seed certification standards even after 12 months of storage period and this combination found superior to others for storage of groundnut produce. In order to standardize the accelerated ageing technique, it was observed that as the temperature and ageing period advanced, the germination percentage declined in both kernels and pods. Maximum reduction in germination was observed after 96 hours in kernels and 168 hours in pods at 41ÂșC. The germination percentages were below the minimum seeds standards for this crop. Thus these conditions were found optimum for performing accelerated ageing test to know the relative storability of seed lots of groundnut varieties. An effort was also made to assess the effect of seed priming treatments on field emergence. Present study revealed that seed treated with GA3 (50 ppm) gave comparatively better results among various treatments for the characters total field emergence and field emergence index in both the varieties while soaking in water in case of MH-4 and hydration dehydration in MH-34 reduced the overall mean germination time.

    Characterization of hybrids and their parental lines in cotton(Gossypium spp.)
    (CCSHAU, 2007) Mohana Kumara. M.R.; Punia, R.C.
    In the present investigation, seven cotton hybrids and their parental lines were studied at CCS Haryana Agricultural University, Hisar during 2006-2007.All the genotypes were studied for characterization based on morphological characters and laboratory techniques. The morphological characters such as Hypocotyl pigmentation, plant height, growth habit, stem hairiness, leaf shape, leaf appearance, leaf pubescence, leaf lobe number, boll surface, boll shape, boll colour,gossypol glands, petal colour, bract type, bract number of serration, anther colour, petal spotting, position of the stigma and petiole pigmentation were found as the most important parameters for characterization. The genotypes were also subjected to sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) of total soluble seed proteins. The findings showed that SDS-PAGE of seed proteins resolve total of 23 bands which were present in different position with different intensity. Band number 19 was present only in Gossypium hirsutum genotypes differentiated from the Gossypium arboreum genotypes. The Flow charts were prepared based on morphological characters and protein fingerprints. The identification keys were also prepared on the stable morphological characters. All the genotypes were differentiated using morphological characters and protein molecular markers.
