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 cytoplasm and cytoplasmicnuclear interaction on downy mildew resistance in pearl millet (Pennisetum glaucum (L.) R. Br.)
    (CCSHAU, 2014) Anil Kumar; Ramesh Kumar
    Forty eight hybrids and their parents of pearl millet were evaluated to study the effect of cytoplasm and cytoplasmic- nuclear interaction on downy mildew (S. graminicola) disease resistance. Genotype mean squares were highly significant for all the characters studied indicating high variability among genotypes. The non-significance of A×R vs. B×R hybrid comparisons for downy mildew incidence revealed that downy mildew is not affected by the cytoplasm. Higher/ equally good number of cytoplasmic effects for various characters in case of A4 and A5 CMS system lines revealed that these lines should be used extensively in breeding programme. The preponderance of magnitude of fixed effect variances due to sca revealed that non-additive gene effects governed the inheritance for almost all the characters except downy mildew. The studies on combining ability revealed that none of the parents– lines (sterile as well as maintainer) and tester proved to be good general combiner for all the characters. The line 4 (81B1) representing A1 system fertile cytoplasm (maintainer) combined favorably for grain yield, dry fodder yield and effective tillers. The tester G73-107 combined favourably for downy mildew resistance. The hybrid 3×11 (81A5×ERC) combined for grain yield and other important traits and also expressed significant positive sca with high per se performance. The same hybrid expressed significant positive heterosis for grain yield, effective tillers, panicle girth, harvest index and downy mildew resistance (negative heterosis) both at 30 days and 60 days. This cross combination 3×11 (81A5×ERC) needs further vigorous testing. The molecular analysis of parental lines by SSR markers (twenty six) exhibited monomorphic pattern for all lines indicating the genetic purity of lines. The study emphasizes on continued and sustained efforts on the cytoplasmic as well as genetic diversification of seed as well as pollen parents.
