Dr. Y. S. Parmar University of Horticulture & Forestry, Solan

Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Solan, was established on 1st December, 1985 with the objective to promote education, research and extension education in the fields of Horticulture, Forestry and allied disciplines. Late Dr. Yashwant Singh Parmar, the first Chief Minister and the architect of Himachal Pradesh perceived the importance of Horticulture and Forestry to develop and improve the State economy which led to the establishment of this University. Its history lies in erstwhile Himachal Agricultural College, Solan, established in 1962 and affiliated to the Panjab University. It became one of the campuses of Agriculture Complex of Himachal Pradesh University on its formation in 1970. Consequent upon the establishment of Himachal Pradesh Krishi Vishvavidyalaya in 1978, this campus became its Horticulture Complex and finally in 1985, assumed the status of a State University, being the only University in the country engaged exclusively in teaching, research and extension in Horticulture and Forestry. The University is located at Nauni in Solan District of Himachal Pradesh, 13 km from Solan on Solan-Rajgarh Road, at an elevation of 1300 metres above mean sea level. Solan town is situated on national highway (NH-22) and is well connected by train and bus services. The University has four constituent colleges, out of which, two are located at the main campus Nauni, one for horticulture and the other for forestry, having 9 and 7 departments, respectively. The third College i.e., College of Horticulture & Forestry is located at Neri in Hamirpur District on Nadaun-Hamirpur state highway, about 6 Km from Hamirpur town and is well connected with bus service. The college offers three Undergraduate Degree Programmes i.e. BSc (Hons.) Horticulture, BSc (Hons.) Forestry and B. Tech. Biotechnology and MSc degree programme in a few subjects. The fourth college i.e. College of Horticulture and Forestry, Thunag (Mandi) is located at Thunag District Mandi. This college offer BSc (Hons.) Horticulture and BSc (Hons.) Forestry degree programme. In addition, there are five Regional Research Stations, 12 Satellite Stations and five Krishi Vigyan Kendras (KVKs) situated in different zones of the State.

    MORPHOLOGICAL, BIOCHEMICAL AND MOLECULAR CHARACTERIZATION OF SOME OYSTER MUSHROOM spp. (Pleurotus spp.)
    (UHF,NAUNI, 2023-05) ANSHU MALA; THAKUR, MANISHA
    Mushrooms are the fruiting bodies of macro-fungi commonly belonging to Basidiomycota and Ascomycota. The genus Pleurotus mushroom generally is called oyster, abalone, tree mushroom and ‘dhingri’ in India constituting about 40 species. There is limited knowledge about genus Pleurotus and the cellular processes involved in the growth of its fruiting bodies at molecular level, hence the study was conducted to assess the morphological, biochemical and molecular characterization of oyster mushroom (Pleurotus species) viz. Pleurotus ostreatus, Pleurotus florida, Pleurotus sajor-caju, Pleurotus citrinopileatus and Pleurotus djamor. At macroscopic level, P. sajorcaju and P. citrinopileatus exhibited largest pileus and longest stipe whereas P. florida and P. ostreatus showed largest basidia and basidiospore at microscopic level. P. florida was found to have the highest total fresh yield (941.35g) on a substrate of wheat straw with the longest cropping time (47 days). Maximum protein (31.64%), crude fat (3.23%), β-carotene (0.144 g/g), lycopene (0.046 g/g), and DPPH scavenging activity (85.24%) were observed in P. djamor; however maximum fibre (16.25 g/g), ash content (9.42 g/g), and total phenolic (0.073 mg/g) content were observed in P. citrinopileatus. These Pleurotus species were further analyzed at molecular level using ISSR primers. Out of 21 ISSR primers, 18 primers were successful in DNA amplification resulting in 136 amplicons, out of which 8 were monomorphic and 128 were polymorphic resulting in 93.08% polymorphism with highest polymorphic information content (PIC) value as 0.432. The ITS and RPB2 DNA barcode regions were investigated in Pleurotus species with 700 bp and 1200 bp, respectively. All of the Pleurotus species had significantly higher levels of 5.8s rDNA and ostreolysin expression in fruiting bodies than in primordia, according to the gene expression analysis. The current study reveals that molecular markers, DNA barcoding and gene expression analysis are helpful techniques for characterizing various Pleurotus species of mushrooms.
