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.

    POLLINATION STUDIES IN JAPANESE PLUM (Prunus salicina Lindl.)
    (2012) THAKUR, MOHIT; SHARMA, GIRISH
    ABSTRACT The present investigation entitled “Pollination studies in Japanese plums (Prunus salicina. Lindl)” was carried out in the laboratory and experimental farm of Department of Fruit Science, Nauni (Solan). Flowering and pollination studies in eight cultivars of Japanese plum were carried out. The data on time and duration of flowering were recorded in each cultivar under study, from the start of flowering to when the last flower opened. The relative size of floral components was determined and pollens were studied for their morphology, viability and germinability. Fruit set under different modes of pollination namely selfing by bagging, hand self pollination, open pollination and cross pollination was determined. Fruits characters namely fruit size, weight, colour, stone size, fruit firmness and adherence of stone to flesh, and physico-chemical characters including TSS, total sugars, reducing and non reducing sugars, titratable acidity and sugar acid ratio were studied. The time of bud burst varied for about one month and average total number of flowering days was 15.37. Maximum flowering was on buds of one year old shoots and spurs, earliest was in Florida 1-2 and last in AURosa. Maximum stamens were in Queen Rosa and Santa Rosa i.e. 33.67. The pollen length and breadth varied from 33.18 to 43.46 μm and 19.98 to 26.19 μm, respectively. The pollen fertility ranged from 72.60 to 84.65 per cent. Pollen germination was highest in Santa Rosa (66.57%) after 72 hours, in 15 % sucrose solution . Cultivar Fortune was best in terms of fruit weight. Cultivars AURosa, Fortune, Queen Rosa and Frontier were found superior for fruit characteristics. Highest total soluble solids were found in AU-Rosa (15 ºB) while total sugars in ‘Frontier’. Cultivars Frontier and Red Beaut were free stone, while others were cling stone. Cultivar Santa Rosa resulted in maximum fruit set of 13.73% through selfing by bagging and cultivar Queen Rosa through open pollination (16.93%). The cultivars Frontier, Red Beaut and Santa Rosa were cross compatible with Santa Rosa, AU-Rosa and Queen Rosa and resulted in maximum fruit set. Santa Rosa pollen resulted in higher fruit set in almost all the cultivars. ‘Frontier’ although a self unfruitful resulted in maximum fruit set when crossed with Santa Rosa. Suitable pollinizers were selected for all the cultivars under study.
