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.

    MOLECULAR AND MORPHOMETRIC VARIABILITY IN Apis cerana F. FROM DIFFERENT AGROCLIMATIC ZONES IN HIMACHAL PRADESH
    (NAUNI,UHF, 2020-10) SAWRAJ JIT SINGH; SHARMA, HARISH KUMAR
    ABSTRACT The present investigations titled “Molecular and morphometric variability in Apis cerana F. from different agro-climatic zones in Himachal Pradesh” were carried out in the Apiculture Laboratory of the Department of Entomology, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) and Molecular Laboratory of the Plant Protection Division, Central Potato Research Institute, Shimla (HP). The current study is the first documentation of molecular characterization of Apis cerana cerana from Himachal Pradesh. Samples of A. c. cerana workers were collected from the nine different locations representing three agro-climatic zones of Himachal Pradesh viz., Palampur and Nurpur (Kangra), Upper Behli (Mandi), Narag (Sirmaur), Mashobra (Shimla), Nauni (Solan), Kalsuin (Chamba), Bajaura and Seobagh (Kullu) during 2019-2020. Morphometric analysis of A. c. cerana showed significant variations revealing no specific correlation with altitude. The observations revealed variations in body length (10.548-12.999 mm), head length (2.803-3.060 mm), thorax length (3.242-3.972 mm), abdomen length (4.333-6.058 mm), antennal length (4.1684.388 mm), proboscis length (5.262-5.727 mm), forewing length x breadth (8.625-8.950 mm x 2.7603.145 mm), hindwing length x breadth (6.068-6.426 mm x 1.665-1.853 mm) and hamuli number (17.55-19.60). The body colour of A. c. cerana workers varied from yellowish brown to blackish brown. Bees collected from Mashobra, Kalsuin, Narag, Palampur, Seobagh and Bajaura were comparatively darker than those from Nurpur, Upper Behli and Nauni. The mtCOI gene characterization of the subspecies possessed genetic distance ranging from 0.000 to 0.009, revealing two distinct clades; the population of A. c. cerana from Palampur (MT027920), Bajaura (MT027915) and Seobagh (MT027917) were grouped together in clade I due to close proximity, while population of A. c. cerana from Mashobra (MT027916), Nurpur (MT027905), Nauni (MT027919), Upper Behli (MT027922), Kalsuin (MT027904) and Narag (MT027921) were clubbed in clade II. The average nucleotide compositions were found to be adenine (32.74 %), thymine (40.71 %), guanine (11.49 %) and cytosine (15.1 %). The phylogenetic results indicate that sub-species from Himachal Pradesh shares close tie with same sub-species from neighbouring country China. Overall, the minimum genetic distance (0.0024) was observed between A. c. cerana from Himachal Pradesh and China (AP017983), whereas, it was maximum (0.0262) in between A. c. cerana from Himachal Pradesh and A. c. indica from Kerala (MH331013). Such variations can be exploited for improving the strain through selective breeding programme.
