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.

    Evaluation and characterization in marigold
    (CCSHAU, 2013) Choudhary, Mahesh; Beniwal, B.S.
    The present experiment was conducted at Experimental Orchard of the Department of Horticulture, CCS Haryana Agricultural University, Hisar during winter seasons of 2011-12 and 2012- 13 on thirty genotypes of both African and French marigold to estimate the genetic variability, heritability, genetic advance and varietal characterization. The observations were recorded on growth, flowering and yield parameters. The analysis of variance revealed that the mean sum of squares due to genotypes were highly significant for all the characters studied, indicating a wide range of variability in the material investigated. The highest flower yield was observed in genotype Hisar Jaffri-2 followed by MGH-09-271 and MGH-09-276, while it was lowest in Hisar Beauty. The high GCV and PCV values were observed for fresh and dry weight of plant, number of secondary branches per plant, number of buds per plant and number of flowers per plant. Heritability in broad sense and genetic advance as per cent mean were higher for fresh weight of plant, dry weight of plant, number of flowers per plant, number of buds per plant and number of secondary branches per plant. Association analysis revealed high significant positive correlation of flower yield per plant with number of secondary branches per plant, number of buds per plant, number of flowers per plant, dry weight of plant, fresh weight of plant, fresh weight of flower, dry weight of flower, plant spread, flower diameter, stem diameter, duration of flowering and days taken to first flower opening, indicating selection of these characters for crop improvement and breeding strategies. Path analysis depicted that number of flowers per plant had the highest direct and positive effect on flower yield per plant, closely followed by fresh weight of flower, flower diameter, dry weight of flower and dry weight of plant. Based on D2 values, all the thirty genotypes were grouped into six clusters in both the years, i.e., 2011-12 and 2012-13, indicating the presence of considerable amount of genetic diversity among the genotypes under study. On the basis of morphological characters, the marigold genotypes were characterized and categorized effectively. The plant growth habit, branching habit, leaflet shape, leaf colour, stalk shape, disc floret, floret colour, etc., were the key characters, therefore, can be used as morphological descriptors for the varietal identification in marigold.
