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.

    BIODIVERSITY AND SYSTEMATIC STUDIES OF THE LEAFHOPPER (CICADELLIDAE: HEMIPTERA) FAUNA OF HIMACHAL PRADESH
    (UHF,NAUNI, 2019-07) THAKUR, PRIYANKA; RANA, RAJINDER SINGH
    ABSTRACT Himachal Pradesh is one of the hubs of biological diversity with varied agro climatic conditions and elevation ranging from 350 to 7000m amsl. The congenial atmospheric conditions are the natural abode and homeland for large number of insects. Despite being one of the most diverse habitats, several insect families remain poorly studied in the state. Cicadellidae one of the largest insect families of order Hemiptera distributed worldwide is one among them. The diversity, species richness, abundance and distribution pattern os f leafhopper speciein all the four agro-climatic zones of the state was explored. The sweep net as well as light traps were used for collecting leafhoppers from all the 12 districts of the state covering 25 locations. A total of 85 leafhoppers species belonging to 61 genera of 12 subfamilies of Cicadellidae were recorded. Of these four species, Gurawa monorcephala Pruthi, Leofa pulchellus Distant, Olidiana kirkaldyi (Walker) and Paralimnellus cingulatus (Dlabola) from subfamilies appeared to be new records from Himachal Pradesh and one species, Pseudosubhimalus sp. 1 was recorded to be new from India. Species richness of leafhopper species increased with the altitude with a hump of the highest species richness as well as diversity in the mid hills zone (651-1800m amsl) following declining trend towards the cold dry zone. Morphological characters taken under consideration for identification of leafhopper species which included: crown, face, compound eyes, ocelli, frontoclypeus, pronotum, scutellum, hind tarsi, hind tibial spinulation, forewing appendix and venation. The male genitalia was the key and the most important taxonomic feature for species identification based on the variation in distinguished features of pygofer, valve, subgenital plate, style, connective and aedeagus. Checklist for the leafhopper species of Cicadellidae collected from all the four agro-climatic zones of Himachal Pradesh was prepared along with the lists of economically important leafhopper species that are well known pests of crops as well as vectors of serious plant pathogenic diseases. The photographs of each recorded specimen were provided along with the diagnostic keys which were prepared for their identification. The distribution of the species might be very useful in future to sketch good pest management practices and policies designed specifically for the particular region. The information generated through this study will be useful for further revision and taxonomical updating of higher level classification of leafhopper fauna of the hill statefor their identification.

    INFLUENCE OF PLANTING DATES, MULCHES AND GA3 APPLICATIONS ON SEED YIELD AND QUALITY OF AFRICAN MARIGOLD (Tagetes erecta L.) CV. ‘PUSA NARANGI GAINDA’
    (UHF,NAUNI, 2018-03) THAKUR, PRIYANKA; DILTA, B.S.
    ABSTRACT The present investigation entitled, “Influence of planting dates, mulches and GA3 applications on seed yield and quality of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda” was carried out at the Khaltoo experimental farm of Department of Seed Science & Technology, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2015 to 2017. The experiment was laid out in Split- Plot Design with 48 treatment combinations of three planting dates (viz., 1st July , 16th July and 1st August), four levels of mulching ( no mulch, crop residue mulch, black plastic mulch and silver-black plastic mulch) and four doses of GA3 (0, 50,100 and 150 ppm ) replicated thrice. Planting of seedlings was done at three different planting dates along with application of different mulches and the treatments of GA3 were applied after 45 days of transplanting as foliar spray. The data were recorded on various growth, flowering, seed yield and quality attributes and subjected to analysis of variance. The results obtained indicated that transplanting of seedlings in the 1st week of July (1st July), mulching of plants with silver-black sheet (M4) and spraying of plants with the highest concentration of GA3 (i.e. 150 ppm) alone as well as in combinations exhibited best performance in terms of minimum days taken to first flowering (days) and attaining maximum values w.r.t. plant height (cm), number of flowers per plant, size of flowers (cm), shoot fresh weight (g), shoot dry weight (g), root fresh weight (mg), root dry weight (mg), number of seeds per head, seed yield per plant (g), seed yield per plot (g), 1000 seed weight (g), germination percentage (%), seedling length (cm) and dry weight (mg), seed vigour index-I (Length) and seed vigour index-II (Mass) as well as lowest electrical conductivity of seeds (dS/m) in comparison to all other treatments. Therefore, transplanting of seedlings be commenced on in 1st week of July (1st July) and mulched with silver- black plastic sheet (M4) along with spraying of GA3 @ 150 ppm after 45 days of transplanting can be recommended for commercial seed production of marigold under mid hill conditions of Himachal Pradesh.

    STUDIES ON GEOGRAPHICAL VARIATIONS AMONG FRUIT FLIES, Bactrocera spp. (DIPTERA: TEPHRITIDAE) IN DIFFERENT REGIONS OF NORTH INDIA
    (UHF,NAUNI,SOLAN, 2017) THAKUR, PRIYANKA; SHARMA, KRISHAN CHANDER
    ABSTRACT The present investigation on “Studies on geographical variations among fruit flies, Bactrocera spp. (Diptera: Tephritidae) in different regions of North India” was carried out during 2014-2015 in the Vegetable Entomology laboratory of the Department of Entomology, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, HP. Five different geographical regions of North India viz. Solan (1,502 mt amsl), Jaach (733 mt amsl), Pantnagar (344 mt amsl), Ludhiana (262 mt amsl) and Hisar (215 mt amsl) were selected to study the variations in the developmental and reproductive biology of two species of fruit fly, viz. Bactrocera cucurbitae and Bactrocera tau under laboratory conditions. The developmental period of B. cucurbitae was found to be maximum in the Hisar population (15.20 days), whereas it was minimum in the Ludhiana population (11.75 days). The total developmental period among the five populations of B. tau was the longest for the Pantnagar population (16.20 days) and shortest for the Jaach (11.60 days) population. Morphometric dimensions of B. cucurbitae revealed significant differences among populations of different geographical regions of North India at different developmental stages. Maximum body length of the adult male and female were observed in the Jaach population (9.11 and11.04mm) and the minimum in Ludhiana population (8.66 and 10.34mm), respectively. Morphometrical analysis of the B. tau reveal that in the adult male and female, the maximum length was observed in the Jaach population (9.41 and 11.78mm) and the minimum in Ludhiana population (9.02 and 11.05mm), respectively. Variations in the fertility parameters of the populations of B. cucurbitae and B. tau collected from five different regions of North India were observed. The highest value of the true intrinsic rate of increase (rm) was observed in the Jaach population (0.148) followed by Solan (0.132), Pantnagar (0.130), Hisar (0.117) and Ludhiana (0.090) populations thus indicating that B. cucurbitae from Jaach region is more generative as compared to the population from other regions. In B. tau, the value of the true intrinsic rate of increase (rm) was also found to be highest for Jaach population (0.153) followed by Hisar (0.140), Solan (0.138), Ludhiana (1.120) and Pantnagar (0.116) thus indicating that the population of Jaach region was the most prolific. Three species of fruit flies, B. cucurbitae, B. tau and B.zonata (19 isolates) were molecularly characterized with mtCOI gene and were submitted to GenBank, NCBI (USA) with accession number KX380855- KX380873. The genetic diversity was too low amongst these populations, considering the geographic scale of the sampling. Seven tomato varieties were screened for the infestation of fruit fly. Avtar, Rakshita, Naveen 2000+, US 2853 and Heem Sohna varieties were found to be moderately susceptible to fruit fly infestation.
