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.

    Molecular analyses of recombinant inbred lines of wheat cross aldan x WH542 for resistance to Karnal bunt (Neovossia indica)
    (CCSHAU, 2010) Gupta, Mamta; Chawla, Veena
    Present studies were conducted on two genotypes, Aldan (resistant) and WH542 (susceptible), and their 94 recombinant inbred lines. Investigations were carried out to screen the recombinant inbred lines (RILs) for Karnal bunt resistance and to characterize above lines using molecular markers. There was significant variation among all the recombinant inbred lines for coefficient of infection of Karnal bunt. The range of coefficient of infection (CI) on the RILs was 0-41.70. The chi-square analysis indicated that a single dominant gene was responsible for Karnal bunt resistance. Thirty five inter simple sequence repeat primers were used for amplification of DNA from the two parents. DNA amplification was observed with only 25 markers. ISSR markers based finger print database were generated using these 25 primers. Out of 25, six primers showed 100% polymorphism. A total of 193 alleles were detected at 25 ISSR loci. The number of alleles per locus ranged from 4-14 with an average of 7.72 alleles per locus. The two parents were genetically divers (similarity coefficient 0.419). The cluster analysis led to distribution into two groups: group 1 had resistant parent Aldan and group 2 had susceptible parent WH542, resistant bulk and susceptible bulk. Among all the primers used one primer (IS-43) was identified to be associated with Karnal bunt resistance. This showed an amplification profile (650 bp product) characteristic of resistant parent, in corresponding bulk and in individual genotyping of the recombinant inbred lines. This might have an application in marker assisted selection after converting it to SCAR marker.
