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.

    STUDIES ON GENETIC VARIATIONS AND ESTERASE ACTIVITY OFHelicoverpa armigeraIN HIMACHAL PRADESH
    (UHF,NAUNI, 2017) CHANDEL, VISHAV GAURAV SINGH; SHARMA, K.C.
    ABSTRACT Geographic variations among different populations of Helicoverpa armigera collected from six different locations viz. Kangra, Solan, Theog and Kinnaur (Himachal Pradesh), Bathinda (Punjab) and Hisar (Haryana) were studied. The variations regarding different morphometric traits, biology, life tables and esterase activity were investigated in the laboratory. In addition to this standard molecular technique RAPD-PCR was also utilized to study the variations among different populations. The studies revealed that the larval and pupal weight was the highest in the Theog population (558.27±11.03, 303.40±12.01 mg) followed by the Solan population (513.58±9.32, 289.61±7.02 mg), whereas, these were the lowest in the Hisar (479.89±9.93, 257.05±3.80 mg) and Bathinda (488.29±6.33, 267.17±3.85 mg) populations. Similarly, the forewing expanse was also the highest for the Theog population (16.94±0.29 mm) followed by the Solan (16.10±0.25 mm), while, it was the lowest for the Hisar (15.47±0.28 mm) population followed by Bathinda (15.53±0.20 mm). The total developmental period was the minimum in the Hisar population (29.24±0.25 days) followed by the Bathinda (31.59±0.30 days), Kangra (31.71±0.36 days), Solan (32.23±0.26 days) and Theog (33.52±0.52 days) population whereas, it was maximum in the Kinnaur population (35.29±0.61 days). The life table studies revealed that the true intrinsic rate of increase (rm) was the highest in the Hisar population (0.126) followed by the Bathinda (0.124), Theog (0.124), Solan (0.123) and Kangra (0.122) populations, whereas it was the least in the Kinnaur population (0.102). The RAPD-PCR studies were conducted with 24 random primers out of which 16 produced amplifiedPCRproducts. Theprimer OPA-05produced maximum 22amplified fragments followed by OPD-01 and OPD-02 producing 21 fragments each. Polymorphism of 71.88 per cent was observed among six populations of H. armigera. The dendrogram constructed after cluster analysis of the similarity coefficients showed three clusters. The Hisar and Bathinda populations formed the first cluster whereas, the Kangra, Solan and Theog populations formed the second cluster. The Kinnaur population formed a separate group individually. The studies on esterase activity of different populations showed that the Bathinda (415.85±7.36 µgm/g/min) and Hisar populations (401.75±1.93 µgm/g/min) had higher general esterase activity and the least enzyme activity was observed in the Kinnaur population (198.88±1.29 µgm/g/min) followed by Solan (241.33±1.69 µgm/g/min), Theog (243.33±2.30 µgm/g/min) and Kangra (292.75±3.94 µgm/g/min) populations indicating thereby a higher level of pesticide resistance in the populations of Punjab and Haryana compared to the populations collected from Himachal Pradesh. The determination of variations among these populations will be helpful in formation of region specific management strategy against this pest.
