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.

    Characterization of pearl millet [oennisetum glaucum (L.) R. Br.] hybrids vis-a-vis their parents
    (CCSHAU, 2012) Satbeer Singh; Yadav, Y.P.
    morphological descriptors with the objective to identify key diagnostic characters of the genotypes. A set of 24 pearl millet genotypes (7 hybrids, 17 parental lines) was evaluated in randomized block design (RBD) with three replications at Hisar and RRS Bawal under irrigated and rainfed conditions, respectively during kharif 2011. Observations were recorded for 34 morphological, seed and yield characters and considerable amount of variation was found in material under study. All the genotypes were classified in different groups for each character. Majority of the qualitative/morphological characters found to be dominant in the hybrids were contributed by the male parent. Bristles (present/absent), nodal pubescence, seed covering were found as dominant characters. Nodal pubescence, nodal pigmentation, spike shape, spike density, spike tip sterility, sheath pubescence and spikelet glum colour distinguished all the 24 genotypes by assigning them key diagnostic features that would certainly help the plant breeders, seed growers and also seed certification agencies to use these diagnostic characters. Hybrids HHB 216, HHB 226, HHB 117 could be differentiated by bristle length, spikelet glume colour and spike tip sterility.

    Studies on genetic distance and hybrid performance in pearl millet [Pennisetum glaucum (L.) R. Br.]
    (CCSHAU, 2016) Satbeer Singh; Pahuja, S.K.
    The present investigation was conducted to estimate genetic diversity at morphological and molecular level; investigate association between genetic distance (GD) and heterosis; and to establish heterotic pool patterns in pearl millet. To assess genetic diversity, a set of 150 (75 B- and 75 R-lines) parental lines were evaluated for grain yield and its component traits in alpha lattice design with three replications at two agroecologically contrasting locations in India (CCSHAU-Hisar in north India under A-zone of pearl millet cultivation, and ICRISAT-Patancheru in peninsular India under B-zone) during rainy season of 2014; and were also genotyped using SSR and SNP markers. Analysis of variance revealed high genetic variability for all the traits in hybrid parents. Mean performance were higher at Patancheru location than Hisar location for most of the traits including grain yield, except for days to flowering, plant height and panicle length. The genetic diversity analysis based on grain yield and its seven component traits clearly partitioned all the seed (B-lines) and restorer parents (R-lines) into two separate clear-cut groups. Many seed and restorer parents clustering together shared common parent in their pedigrees indicating genetic similarities of clusters. Fifty six SSR loci detected 412 alleles (average of 7.36 alleles per locus) in 147 hybrid parents of pearl millet, while 9006 SNP loci were detected in 117 hybrid parents. Both the markers (SSR and SNP) also clustered majority of the B- and R-lines into two clear cut separate groups indicating existence of two broad based gene pools in pearl millet. A set of 17 diverse parents selected using SSR based genetic distance to investigate correlation between GD and hybrid performance was used to develop a set of 136 hybrids following diallel mating design; evaluated along with parents and standard hybrid checks for grain yield and its component traits at Hisar and Patancheru during rainy season of 2015. Wide range of mid-parent, better parent and standard heterosis was observed for majority of the traits. Genetic distance had low significant positive correlation (r= 0.42) with heterosis for grain yield, but it was found higher in genetically closer group of parents than in diverse ones. The correlation of heterosis with SSR based GD was higher than that of GD based on SNPs or Euclidean distance (ED) and heterosis. Based on heterotic patterns, B- and R-lines were found to be representing two broad based heterotic pools in pearl millet. Further, four (HP1, HP2, HP3 and HP4) heterotic pools for pearl millet hybrid parents were identified based on multilocation data, while heterotic pools were found to differ for different agro-ecologies, and three heterotic pools each for A-zone of pearl millet cultivation in India represented by Hisar location (HP1-AZ, HP2-AZ and HP3-AZ), and for Bzone represented by Patancheru location (HP1-BZ, HP2-BZ and HP3-BZ) were identified.
