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.

    Phenotypic and genotypic diversity in pearl millet [Pennisetum glaucum (L.) R. Br.] germplasm lines
    (CCSHAU, 2015) Jyoti; Dev Vart
    Phenotypic and genotypic diversity in pearl millet [Pennisetum glaucum (L.) R. Br.] was studied in a set of 48 maintainer lines using 30 morpho-agronomic traits (16 qualitative and 14 quantitative) and 22 SSR markers. Significant mean sum of squares indicated sufficient variation in the lines. Leaf sheath length, number of productive tillers/plant, plant height, 1000 grain weight, grain yield/plant had high GCV, PCV, heritability and genetic advance as % of mean. Correlation coefficient analysis revealed that days to 50% flowering, spike length, number of productive tillers per plant, 1000 grain weight, dry and green fodder yield were significantly and positively correlated with grain yield per plant. Path coefficient analysis revealed that days to 50% flowering, spike length, number of productive tillers/plant had high significant direct contribution towards grain yield/plant. First five principal components explained 81.02% of accumulated variability. D 2 analysis led to formation of seven clusters. The highest inter-cluster distance was found between clusters 1 and 7. Based on Principal Component and factor analysis, genotypes HMS 43B, HMS 45B, HMS 60B, ICMB 97111, Tift 23 D 2B etc. showed high grain yield and high number of productive tillers/plant and plant height. Genotyping of maintainer lines with 22 polymorphic SSR markers lead to formation of 8 groups. Three out of 22 polymorphic primers showed PIC value of more than 0.70. Phenotypic and genotypic clustering showed that some genotypes grouped together in the two data sets.
