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.

    Genetics of Bacterial Leaf Blight (BLB) resistance in advanced lines of cluster bean
    (CCSHAU, 2011) Anil Kumar; Kadian, S. P.
    The present study was conducted on segregating populations of two crosses viz. HG 563 (Resistant) X PNB (Susceptible) and HG 75 (Resistant) X PNB (Susceptible) grown during kharif 2010 to screen advanced F3 and F4 progenies for bacterial leaf blight resistance under artificial inoculated conditions, F2 populations for number of gene governing resistance and to perform diversity analysis in advance lines for resistance and yield components. Observations were recorded on plant height, number of branches per plant, number of pods per plant, seeds per pod, 100 seed weight, seed yield per plant, bacterial leaf blight disease incidence, days to 50 per cent flowering, days to maturity, crude protein content, gum content and total phenol. In F2 populations of both crosses, a ratio of 13 : 3 was observed which indicated the presence of epistatic (Inhibitory) interaction. Hierarchical cluster analysis indicated that Clusters I and III gave the best performance for yield and its components in cross HG 563 X PNB and clusters I, III and V were found better in cross HG 75 X PNB. In principal component analysis, first principal component explain 78.93 per cent and 78.47 per cent variability in crosses HG 563 X PNB and HG 75 X PNB, respectively. In cross HG 563 X PNB, variables exhibited high loading of different factors in such a manner that principal factor I and principal factor III could be designated as yield factor and disease factor, respectively. In another cross HG 75 X PNB, principal factor I and principal factor II could be designated as maturity factor and yield factor, respectively. Total phenolic content was increased as disease reaction increase in plants.
