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.

    Biosynthesis and characterization of silver nanoparticles using S. mukorossi extract possessing antimicrobial potential
    (College of Horticulture and Forestry Dr YSP UHF, Neri, Hamirpur(H.P.), 2023-11-28) Thakur, Sapna; Sharma, Sneh
    The present study on the “Biosynthesis and characterization of silver nanoparticles using S.mukorossi extract possessing antimicrobial potential” were carried out in Department of Biotechnology, College of Horticulture and Forestry (Dr. Y.S. Parmar University of Horticulture and Forestry), Neri, Hamirpur (H.P) during 2022-2023. Sapindus mukorossi is an extremely valuable cultivated medicinal plant which is mostly found in hilly regions of India. In the lists of herbs, it is a popular herb in Ayurveda and is used as an important ingredient in cleansers and shampoos. It is well known for its folk medicinal values and known by several names like washnut, soapnut, soapberry, dodan and ritha. The use of this plant promoted considerable attention because of their various biological and pharmacological activities. The major compound isolated from genus Sapindus are saponins, triterpeniods, fatty acids and flavonoids are well known for their antimicrobial, antidiabetic, cytotoxic, fungicidal, and anti-inflammatory activities. The study was undertaken for biosynthesis and characterization of silver nanoparticles derived from S. mukorossi pericarp extract. The sample was collected from village Sheglagalu, Chail Chowk, Distt. Mandi (H.P). Synthesis was carried out using different solvents viz., methanol, chloroform and aqueous. It was found that distilled water acts as a better solvent for the synthesis of silver nanoparticles. The characterization of prepared silver nanoparticles was assessed using distinct techniques namely UV-vis spectroscopy, X-ray diffraction (XRD), Fourier transmission infrared (FTIR) and High resolution- transform electron microscopy (HR-TEM). The antioxidant activity of aqueous extract and biosynthesized silver nanoparticles was evaluated using DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The different concentrations of sample ranging from (100-1000 µg/ml) was prepared and mixed with 3 ml of DPPH solution. The maximum antioxidant activity was confirmed at 1000 µg/ml of concentration that is 91 % and 88 %, respectively. The antimicrobial property of silver nanoparticles derived from S. mukorossi extract was evaluated against four strains viz., P. aeruginosa, E. coli, B. subtilis and S. aureus. The maximum antimicrobial property was seen against gram-negative bacterium P. aeruginosa, E. coli then gram-positive bacterium B. subtilis and S. aureus. These results suggest that silver nanoparticles made from S. mukorossi extract may beused as antimicrobial and antioxidant agents in several fields, including medicine, agriculture, and personal care products.

    Development of new clones of Salix (willow) through control breeding
    (YSPU, 2015) Thakur, Sapna; Singh, N.B.
    The present investigation entitled “Development of new clones of Salix (willow) through control breeding” was carried out in the Department of Tree Improvement and Genetic Resources, Dr Y. S. Parmar University of Horticulture & Forestry Nauni, Solan (HP) during 2013-2015. There is a collection of Salix clones/ strains/ species procured from different countries covering five continents namely Europe, North America, South America, Asia and Africa and maintained in the germplasm block of Naganji nursery from which eight clones were included in the study and the plant material of 4 females (PN 227, J 799, S. babylonica and S. tetrasperma ) and 4 male (NZ 1140, Austree, J 795 and S. tetrasperma ) clones were crossed using Line x Tester (4 x 4) mating design. Control crossing was done and seedlings were raised in the nursery in RBD at stage-1 and were evaluated for morphological characters. In stage-2 clonal cuttings of selected individuals and parents were raised in RBD and were evaluated for morphological, physiological and wood characters. Line x tester analysis for combining ability revealed that that line PN 227 and tester Austree were found to be good general combiners. On the basis of heterosis over better parent, mean performance and significant desirable SCA effects for morphological, physiological and wood characters the combinations PN 227 x Austree, PN 227 x NZ 1140 and PN 227 x J 795 were found to be the most promising families.The estimates of GCA variance ( 2 GCA) were more than the SCA variance ( 2 SCA) for all the characters studied. The gene action study revealed that additive variance was observed more than the dominance variance for all the parameters studied. The proportional contribution of lines was higher than individual contribution of testers or line × tester interaction except for fresh root weight, dry shoot weight, dry root weight, total dry weight, wood density and fibre length. The 10 SSR markers data disclosed that 12 hybrids were highly similar to their female parents and whereas 4 hybrids were more similar to the male parent. On the basis of population structure analysis it is concluded that this hybrid population structure is diverse and in future such information will be useful for conducting association mapping for the traits of economic importance.
