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.

    Studies on molecular characterisation, heterosis and combining ability in forage sorghum [Sorghum bicolor (L). Moench]
    (CCSHAU, 2017) Dehinwal, Ashok Kumar; Pahuja, S.K.
    The present study was undertaken to estimate economic heterosis, combining ability with the objective of exploring possibilities of its commercial utilization and stability analysis in four different environments. The material for the present investigation comprised of twenty four forage sorghum hybrids developed between six female parents (lines) and four male parents (testers) in line x testers mating design alongwith two standard checks (SSG 59-3 and MFSH 4). The crosses were made at research area of forage section, CCS HAU, Hisar during the kharif season of 2014-15. Hybrids and parents were evaluated at two locations i.e. research area of forage section, CCSHAU, Hisar and RRS Uchani, Karnal with two dates of sowing (Early and late sowing) during the kharif season of 2015-16. All the thirty six genotypes were grown in a randomized block design with three replications in a two-row plot of 4.0 m length. Data on five randomly taken plants from each genotype in each replication were recorded on different quantitative characters viz. Days to 50% flowering, plant height, number of tillers per plant, leaf length, leaf breadth, stem diameter, green fodder yield, dry fodder yield, and different quality characters viz. TSS content, protein content, protein yield, IVDMD [(in vitro dry matter digestibility), dry matter digestibility (DDM) and HCN content in all the four environments. All data on these quantitative and quality characters were recorded at first cut (55 days after sowing) and second cut (45 days after first cut) separately in all the four environments. Out of 44 SSR primers twelve showed polymorphism. The NTSYS-PC UPGMA cluster tree analysis led to the grouping of ten parental genotypes into two major clusters at similarity index 0.60 which were further divided to sub cluster I, II, and III. Early sowing at hisar (E1) and karnal (E2) were better environments for green and dry fodder yield than late sowing at hisar (E3) and karnal (E4). Hybrids 465A × HJ 513, 467A × G 46 and 9A ×IS 2389 recorded maximum green fodder yield. These hybrids were also good for dry fodder yield, leaf length, leaf breadth, protein yield, IVDMD and DDM. The combining ability analysis revealed that non- additive variance was more than additive variance in the expression of all the traits. Among female parents, 9A and 14A and among male parents, HJ 513 and G 46 were the good general combiners. Hence these may be used for future breeding. Hybrids 465A × G 46, 467A × IS 2389 and 31A × IS 2389 for green fodder yield and dry fodder yield were found stable, average responsive and suitable for all the test environments.

    Genetic variability for different biometrical and harvest plus traits in pearl millet {Pennisetum glaucum (L.) R. Br.}
    (CCSHAU, 2013) Dehinwal, Ashok Kumar; Yadav, Yash Pal
    The present investigation was carried out to study genetic variability for different biometrical and harvest plus traits and association among the different traits in pearl millet. The experimental material was comprised of 100 advance inbred lines grown in randomized block design in two replication during kharif 2012. The observations were recorded for 12 field traits [Days to 50 per cent flowering, plant height (cm), spike length (cm), spike girth (cm), total tillers (number/plant), effective tillers (number/plant), leaf length (cm), leaf width (cm), ear weight (g), grain yield (g/plant), dry fodder yield (g/plot), 1000-grain weight (g)] and harvest plus traits [ Iron and Zn content (mg / kg grains)]. Dry fodder yield, grain yield, ear weight, iron content and 1000-grain weight had high heritability and high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) Correlation study revealed that grain yield per plant expressed positive significant correlation with dry fodder yield followed by ear weight, total tillers /plant, effective tillers/plant and plant height. The path coefficient analysis suggested the importance of dry fodder yield, ear weight, total tillers /plant, effective tillers /plant, leaf length and zinc content as these had positive direct and indirect effects on grain yield. Therefore, selection for higher yield will be useful if it is based on traits such as dry fodder yield, ear weight, total tillers/ plant and effective tillers/plant. Inbreds 12-0125 [1660 (M.T.)], 12-0069 (IPS 98-2) and 12-0107 (H 08/004) were found better not only for grain yield but also for traits viz., plant height, spike girth, total tillers per plant, effective tillers per plant , leaf width, ear weight, dry fodder yield and iron & zinc content
