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.

    SERODIAGNOSTIC STUDIES ON VIRUSES INFECTING APPLE
    (UHF,NAUNI,SOLAN, 2010) KATWAL, VINAY SINGH; HANDA, ANIL
    ABSTRACT Investigations were conducted to record the incidence of viruses in apple orchards of the state along with serological detection by employing ELISA, besides indexing of some trees of commercial cultivars of apple. Seventeen apple orchards surveyed in Shimla, Kinnaur and Kullu district of HP revealed the presence of viral infection with an incidence of 5-99 per cent. Both indirect DAC ELISA and direct DAS ELISA assays resulted in detection of ACLSV, ApMV, ASGV and ASPV in apple trees of different commercial cultivars being grown in different orchards. ACLSV, ApMV, ASGV and ASPV were found to be present in serologically detectable limit in leaves, bark and petals parts of an infected plant. However leaf sample drawn during June, bark taken during August and petals taken during April month found to contain highest relative concentration of these viruses based on the OD values obtained in serological reactions. About 50 per cent of the diseased plants revealed the presence of two or more than two viruses, thus indicating prevalence of mixed infection. Out of 115 asymptomatic apple trees of different commercial cultivars selected through viral indexing, 4 trees were found to carry latent infection of ACLSV. Virus tested trees were marked to serve as mother trees for providing budwood use in propagations.

    STUDIES ON BACTERIAL BLIGHT OF POMEGRANATE CAUSED BY Xanthomonas axonopodis pv. punicae (Hingorani and Singh) Vauterin et al.
    (2015) KATWAL, VINAY SINGH; SHARMA, R.C.
    ABSTRACT The present investigation entitled “Studies on bacterial blight of pomegranate caused by Xanthomonas axonopodis pv. punicae (Hingorani and Singh) Vauterin et al” was conducted in the laboratories of Department of Plant Pathology and experimental farm of Department of Fruit Science during the year 2012 to 2014. Considering the magnitude and losses due to bacterial blight in pomegranate, investigations were undertaken on cause of the disease, variability, epidemiological factors and management aspects. Survey revealed that disease was prevelant in nine districts of Himachal Pradesh with highest incidence and severity in Jachh in Kangra district. The bacterium was rod shaped, gram negative and non-spore forming. It was positive to starch hydrolysis, gelatin, liquefaction and H2S production. Yeast extract dextrose broth was found superior in supporting the growth of the pathogen at a temperature of 28±1oC with a pH range of 6.5. Study on 20 different bacterial isolates revealed variations in growth and colour in cultural studies, size in morphological and appearance of symptoms in pathogenic studies. The isolates exhibited 100 per cent polymorphism for OPA-2, OPB-1, OPF-7 and OPF-10 primers showing significant molecular variability. The infection rate increases as rainfall, temperature and relative humidity favours the disease development and spread, in 2012 and 2013 on both leaves and fruits. The AUDPC was maximum on leaves as compared to fruits in both the years. None of the tested weeds were found as collateral host of the pathogen. All the pomegranate germplasm was moderately to highly susceptible against the disease. Salicylic acid (100 ppm) was effective under pot and field conditions to reduce the disease severity. Pseudomonas fluorescens and cow urine (5%) were significantly effective in reducing the disease severity under in vitro, pot and field conditions. Clove oil, eucalyptus oil and neem oil reduced the disease severity under in vitro, pot and field conditions, respectively. Among chemicals streptocycline (100 ppm) and Bordeaux mixture 1% spray was very effective in reducing the disease severity under in vitro and field conditions. COC (0.25%) + streptocycline (0.01%) as paste treatment was highly effective in managing the disease. Application of Bordeaux mixture (1%) + bleaching powder (100g/plant) reduces the initial inoculum in the field. Pruning in the month of December and January reduces the disease severity to some extent. Application of NPK and multinutrients lowers severity of the disease under field conditions. The IDM strategy evaluated was found successful and feasible in managing the disease than individual treatments for disease control.
