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.

    IDENTIFICATION AND CHARACTERISATION OF BUD SPORTS IN APPLE (Malus × domestica BORKH
    (UHF,NAUNI, 2021-11) ANSHUL KUMAR; SHARMA, D P
    ABSTRACT The apple (Malus x domestica Borkh.) is among the most diverse and economically important fruit species in the family Rosaceae. Its popularity in terms of market demand is dependent on its nutritional value, broad health benefits and high quality, which includes size, flavour, sweetness, texture as well as excellent peel colour. Apple as highly commercial temperate zone crop in India, and breeding for horticuturally important traits and fruit quality is thus a major concern for plant breeders. Genetic improvement by conventional methods is a very slow and cumbersome process owing to perennial nature, long juvenile phase, heterozygosity, and sexual incompatibilities, in such cases spontaneous mutation can be used as speedy method of improvement. Keeping the above in mind present investigation entitled “Identification and characterisation of bud sports in apple (Malus x domestica Borkh.)” was undertaken during 2018- 2021. Field surveys were conducted in different orchards of Shimla, Kinnaur, and Lahaul & Spiti districts of H.P. and efforts were made to identify bud sports in apple. Around 100 orchards were examined, and over 10000 bearing trees were screened to locate bud sports relying on pre-selection criteria, resulted in the identification of 19 bud sports that varied from their respective mother trees in one or more important traits. Out of nineteen 10 were early and solid coloured (AKM, GRK, KRT, KCS, PCS, PSK, VMK, SNR, TKL and DDK), six late colouring (SK2G, CK, SK1, KAH-1, SLN, MNSR), one half red half green colouring (JCS), one late and distinctive fruit colouring (UKL) and one Early, solid and unique fruit peel colour development (DSK) bud sports were observed in different orchards and marked for further evaluation studies. In the current study, 50 genomic and 10 EST derived simple sequence repeats (SSR) markers were used to determine differences between identified bud sports and their corresponding mother trees in order to validate the observed variations in the bud sports out of 19 only 11 showed variations among bud sports and their mother plant. Out of all 19 identified bud sports in current study, 11 bud sports (DSK, VMK, KCS, DDK, SK2G, PCS, SNR, MNSR, KRT, CK and SK1) showed the genetic variations between bud sports and mother plants. Whereas, remaining 8 show no variation through SSR primers. These bud sports may require more specific SSRs to validate the variation among them or these bud sports may be simply epigenetic modifications. The identified bud sports were vegetatively propagated for further studies in future
