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.

    Genetic analysis of natural variability in Sesame (Sesamum indicum L.)
    (CCSHAU, Hisar, 2023-07-24) Rohit; Subhash Chander
    The study was carried out to investigate genetic variability and to assess genetic diversity in 50 sesame genotypes. During kharif 2022, the experiment was conducted in Randomized Block Design with three replications at the experimental area of Oilseeds Section, Department of Genetics and plant breeding, CCS Haryana Agricultural University, Hisar. Each genotype was sown in single row of 3-meter length with spacing of 30 x 15 cm and evaluated for twelve quantitative characters. Analysis of variance showed highly significant differences in the material for all the studied characters. Highest genotypic and phenotypic coefficient of variation was found for seed yield/plant followed by secondary branches/plant, number of capsules/plant, number of primary branches/plant and number of seeds/capsule. High heritability coupled with genetic advance was observed for number of primary and secondary branches/plant, number of capsules/plant, number of seeds/capsule and seed yield/plant. The seed yield/plant showed a significant positive correlation with plant height, number of primary branches/plant, number of capsules/plant, number of seeds/capsule, capsule length, capsule width and 1000-seed weight, and negative correlation with days to 50% flowering, days to maturity and oil content. Path analysis revealed that primary branches/plant and capsule length had positive effects on seed yield/plant while negative effect was shown by days to 50% flowering and oil content. The D2 analysis classified all the genotypes into five clusters. Cluster II had the highest number of genotypes followed by cluster III and cluster I. The highest inter-cluster distance was observed between clusters I and II. Maximum contribution towards genetic divergence was due to secondary branches/plant (20.94%) followed by primary branches/plant (19.51%) and seed yield/plant (17.59). In conclusion, the genotypes NIC-17274-C and NIC-7897 (Cluster I), NIC-8394 (Cluster III) and HT-2 (Cluster IV) should be used in hybridization programme for improvement of seed yield and oil content in sesame.

    Impact of seed treatments on quality of different aged seeds of oat (Avena sativa L.)
    (CCSHAU, Hisar, 2023-07-20) Rohit; V.S. Mor
    The present studies entitled “Impact of seed treatments on quality of different aged seeds of oat (Avena sativa L.)” were carried out at Laboratory and field of Department of seed science and technology, CCS HAU, Hisar. The seed treated with Azotobacter+Phosphate solubilizing bacteria enhanced the seed quality in terms of all parameters of fresh, one year old and two year old seed lot of oat and Chlorpyrifos and their combinations showed negative effect on seed quality. Among the three years seed lots, highest performance were observed in freshly harvested seeds for various seed quality parameters i.e radicle emergence (88.69%), speed of germination (54.33), standard germination (93.46%), seedling length (40.94 cm), seedling dry weight (12.37mg), vigour index-I (3,829.30), vigour index-II (1,156.93), field emergence index (9.75), seedling establishment (69.96%) and plant height (28.75cm) at 30 days whereas, the maximum enhancement in standard germination and vigour indices was observed in one year seed lot and the minimum was observed in fresh seed lot. The correlation study shows that the field emergence of oat had positive and significant correlation with germination percentage, seedling length and seedling dry weight. The seedling establishment was also found significantly correlated with vigour index-I, vigour index- II, field emergence and speed of germination. Similarly, field emergence index was significantly correlated with vigour index-I, seedling length, vigour index- II, seedling dry weight, germination percentage and non-significant with speed of germination. The seedling establishment of oat in the field was found to have significant positive correlation with most of the seed quality parameters such as germination percentage, seedling length and seedling dry weight but negative correlation with radicle emergence.
