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.

    Synthesis of possible potent herbicidal organic compounds using green catalysts
    (CCSHAU, 2019) Pooja; Rajvir Singh
    Every day there is a new invention in the field of chemistry but the people are curious about how much they are benign to us. Green chemistry serves as a tool to reshape the chemical processes to make them clean. Thus, green chemistry is the future chemistry which is simple, efficient and benign in all steps of particular synthesis processes. Coumarins, Imidazoles and Dihydropyrimidinones are versatile classes of heterocycles and intermediates for the preparation of other organic compounds due to their effective biological activities. For the preparation of these compounds and their derivatives, different reagents are being used which are quite hazardous to the environment and human health due to their toxic nature. Since last few years, attempts are being made for ecofriendly synthesis by using a green catalyst. Green catalyst is a megahit catalyst which is helpful to overcome the negative environmental effects due to various hazardous and toxic chemicals used in synthetic pathways. Hence, the most important aspect of green chemistry is the use of green catalysts in chemical reactions. Therefore an attempt has been made to synthesize above mentioned classes of compounds by using various green catalyst (Potassium dihydrogen phosphate, Oxalic acid, Citrus limetta juice, Pineapple juice and Lemon juice). These compounds were characterized by spectroscopic technique viz. 1HNMR, IR, Elemental analysis and other analytical data. Synthesized compounds were screened for herbicidal activity at 50, 100, 150 and 200 g/mL concentrations. Compounds 11, 28 and 40 were found more active against the root and shoot of Raphanus sativus L.due to the presence of methyl, chloro and methoxy group (electron-donating groups) as substituents respectively.

    Dissipation and decontamination of chlorantrantraniliprole in okra
    (CCSHAU, 2019) Pooja; Sushil
    Dissipation and decontamination of chlorantraniliprole (Coragen 18.5% SC) in okra and soil (at harvest time) was studied following foliar spray on okra at recommended (30 g a.i. ha-1) and double of recommended (60 g a.i. ha-1) by Central Insecticide Board (CIB). The residue of the insecticide was analyzed using GC – MS/MS with a triple Quadruple analyzer, operated in the positive ion mode using multiple reaction monitoring (MRM) of the transitions m/z 278 > 249 and 278>251. Recovery experiment was performed on okra and soil sample fortified @ 0.01, 0.05 and 0.10 mg kg-1and the observed recoveries were in range 85.23 – 88.79 % and 84.65 – 88.65% respectively. The initial deposit of CAP residue in okra fruit was 0.077 and 0.140 mg kg-1 for single (T1) and double (T2) dose respectively. These residues dissipated following first order degradation kinetics with half -life 1.90 and 1.92 days and reached below quantified level (LOQ i.e 0.01 mg kg-1) on 7th and 10th day for single (T1) and double (T2) dose respectively. In soil (at harvest time) the residue level was < LOQ for both doses. The decontamination processes dislodges the chlorantraniliprole residue to the extent of 84.00 – 38.89% from okra fruits and washing followed by boiling was found more effective i.e. 84.00 % in dislodging residue of chlorantraniliprole than washing alone and unwashed conditions.

    Genetic divergence analysis for morphological and biochemical traits in Desi cotton (Gossypium arboreum L.)
    (CCSHAU, 2019) Pooja; Pundir, S.R.
    The present investigation entitled “Genetic divergence analysis for morphological and biochemical traits in Desi cotton (Gossypium arboreum L.)” was carried out at the Research area of Cotton Section and Biochemistry Laboratory, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar (Haryana, India) during Kharif 2017-18. The observations were recorded for different quantitative and biochemical characters to assess the genetic diversity in 60 Desi cotton genotypes. The GCV and PCV were observed high for seed cotton yield /plant, plant height (cm), number of bolls /plant, lint yield /plant (g), and protein content (%). High heritability was observed for almost all the characters studied except number of monopods /plant. The highest genetic advance as percent of mean was recorded for traits like lint yield /plant (g), seed cotton yield /plant and gossypol content (%). Hence, on the basis of highest value for component of variation and variability parameter direct selection for traits would be most effective. Seed cotton yield /plant had a positive and highly significant correlation with trait like number of monopods /plant, number of bolls /plant, boll weight (g), lint yield /plant (g), seed index and lint index at genotypic level indicated that there was strong inherent association between these traits. On the basis of cluster analysis sixty Desi cotton genotypes were grouped into seven clusters, indicated the presence of substantial genetic diversity in the evaluated germplasm lines/genotypes. In this context, the highest intra-cluster distance was observed in cluster V and lowest in cluster II. The maximum inter-cluster distance were showed between clusters II and IV, whereas, the minimum inter cluster distance was noticed between cluster III and VII, followed by clusters I and II. The genotypes of cluster III viz; FFS-1, Garovilli, H 476-5, HD 10, HD 3 and HD 20 were best performing. Based on study of morphological genetic diversity, the genotypes viz., BH 92, DC-93, HD 5278, FFS-9, BH 102, AC 33, HD 351, HD 372, BH 41, N-W-1, HD 392, G 20 and G 23 showed sufficient amount of genetic diversity for yield and its component traits which may be used in cotton breeding programmes for further improvement.
