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 SEED TRANSMISSION OF ANTHRACNOSE IN BELL PEPPER (Capsicum annuum L.)
    (UHF,NAUNI, 2017-09) CHAITRA, V; BHARAT, NARENDER K.
    ABSTRACT The present investigation entitled “Studies on seed transmission of anthracnose in bell pepper (Capsicum annuum L.)” was carried out in the Department of Seed Science and Technology, Dr. Y. S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2016-17. Two laboratory experiments were undertaken following Completely Randomized Design. The cultivar used was Solan Bharpur. Under first experiment Anthracnose or ripe fruit rot (Colletotrichum capsici) infected fruits were harvested at the maturity. On the basis of fruit infection level i.e. lesion size on the mature fruits seven treatment were kept viz., control (apparently healthy fruit), 1-5 mm, 6-10 mm, 11-20 mm, 21-30 mm, 31-50 mm and >51mm). Seeds from these fruits were extracted separately and subjected to seed quality and health testing following methods like Standard blotter paper methods, Roll paper method, Agar plate method and Grow out test. Seed germination (%), vigour index I & II and other seed quality parameters like seedling establishment (%), speed of germination were found highest in control treatment (seeds taken from apparently healthy fruits). Whereas the per cent infection of seed with Colletotrichum capsici, Alternaria sp., Fusarium sp. and Aspergillus sp. was observed highest in T7 (Fruit lesion size of 51 mm and above). In the second experiment healthy seeds of the same cultivar were artificially inoculated with the culture of Colletotrichum capsici grown on PDA. There were 8 treatments on the basis of the age of the culture used for inoculation separately viz., 1-3 days, 4-7 days, 8-11 days, 12-15 days, 16-19 days, 20-23 days, 24-27 days old culture and control. The inoculated seeds were subjected to seed quality and health testing following the same methods as under the first experiment. Seed germination (%), vigour index I & II and other seed quality parameters like seedling establishment (%), speed of germination were highest in control treatment. Whereas the per cent infection of seed with Colletotrichum capsici, Alternaria sp., Fusarium sp. and Aspergillus sp. was highest in T7 (24-27 days old culture) which was at par with T6 (20-23 days old culture). From these studies it can be concluded that the percent germination and other quality characters of the seeds extracted from the anthracnose infected bell pepper fruits (cv. Solan Bharpur) with lesion size up to 10 mm were not affected much and were similar to the seeds extracted from the apparently healthy fruits, where as the seeds extracted from the fruits with lesion size of more than 20 mm showed a sharp reduction in percent germination and seed quality parameters and the effect was similar as in case of seed extracted from severely infected fruits. The seeds extracted from anthracnose infected fruits also showed higher infection/contamination of Colletotrichum capsici as well as other seed microflora like Fusarium sp., Alternaria sp. and Aspergillus sp. Under artificial inoculation condition the germination and seed quality parameters were drastically reduced by the inoculation with fungal culture which was more than 15 days old. The seed also showed infection of C. capsici even after the surface sterilization. However, seed infection/contamination with C. capsici was reduced upto 50 per cent upon sterilization with sodium hypochlorite (1%). It also indicated that C. capsici is both internally as well as externally seed borne. Percent seed transmission (seed to plant) of C. capsici was recorded more than 20 per cent in naturally infected seeds and 17 per cent in artificially inoculated seeds.
