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 REPRODUCTIVE BIOLOGY OF WILD POMEGRANATE (Punica granatum L.)
    (UHF,NAUNI, 2014) DHIMAN, JYOTI; GUPTA, TARA
    ABSTRACT The present investigation entitled “Studies on Reproductive Biology of Wild Pomegranate (Punica granatum L.)” was carried out at two sites namely Tatool (S 1 ) and Narag (S 2 ) in the Department of Forest Genetic Resources, Dr. Y. S. Parmar University of Horticulture & Forestry Nauni, Solan (HP) during 2013-2014. The phenological studies inclusive of phenophases, vegetative characters and reproductive characters observed earlier in Tatool (S 1 ) followed by the second site: Narag (S2 ). There was significant variation observed in leaf morphometeric characters within trees. Maximum values for leaf size and leaf area was observed for those leaves borne on lower position of trees in both the sites. The reproductive bud appear on axillary and terminal position of the tree in cymose inflorescence. On the basis of sizes and development stages, the flower buds were assorted into ten different stages. The protogynous stigma was firstly seen protruding out with the onset of anthesis and the receptivity period was recorded to persist till third day. The stigma protrudes out of the calyx during the ninth bud stage and it is protogynous in nature and becomes receptive one day before anthesis. Anthesis of flowers was observed to take place 10 am to 2pm. Pollen germination percentage of freshly collected pollen was higher in 12.5% sucrose + 10 ppm Boric Acid. Fresh pollen viability percentage was higher in hermaphrodite flowers for all the trees. The pollinations success among different breeding system was maximum observed in open pollination. The pollination success observed for controlled pollination between different trees of both sites was higher than open pollination, geitenogamy and selfing. The flowers were foraged during daytime by different species of insects representing bees, black ants and birds. The nursery growth performance of the progeny seedlings also studied and the maximum mean seedling height was recorded from T 3 S 2 x T 4 S 1 (73.15 cm), whereas maximum mean collar diameter (6.59 mm) was registered by the T 4 S 2 x T 1 S 1 progenies.

    PROVENANCE STUDIES IN Albizia lebbek Benth.
    (2012) GANGADHARRAO, DHUPPE SUKESH; THAKUR, I.K.
    ABSTRACT The present investigation entitled “Provenance studies in Albizia lebbek Benth.” was carried out at the research field, Department of Tree Improvement and Genetic Resources, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2011-12 to evaluate fifteen provenances of Albizia lebbek from Himachal Pradesh. The experiment was laid out in a RBD with three replications. Provenances were evaluated for some phenotypic characters of plus trees, seeds and seedlings and their fodder quality traits. Analysis of variance showed significant differences for all the characters under study. In this study highest mean values for 100 seed weight, seed length and seed width were recorded in P6 (Jachh) provenance and seed germination percentage in P9 (Mubarakpur). Maximum values for biomass traits were found in P11 (Dhaulakuan), P7 (Khatiyad) and P5 (Dehari). Similarly P5 (Dehari), P9 (Mubarakpur) and P12 (Shambuwala) provenances were found superior for fodder quality traits. High heritability coupled with high genetic gain estimates were recorded in characters viz. germination (%), survival (%), seedling height (cm), collar diameter (cm), no of leaves, shoot fresh weight (g), shoot dry weight (g), root fresh weight (g) and root dry weight (g). The shoot dry weight showed highly significant positive genotypic as well as phenotypic association with seedling height, collar diameter, shoot fresh weight, root fresh weight and root dry weight which suggests that shoot dry weight can be improved through selection for these traits. Furthermore divergence studies indicated that hybridization between provenances from cluster III and IV can be utilized for getting the superior recombinants in segregating generations.

    VARIATION STUDIES IN Ulmus villosa BRANDIS
    (2012) THAKUR, SAPNA; THAKUR, I.K.
    ABSTRACT The present investigation entitled “Variation studies in Ulmus villosa Brandis” was carried out at the experimental field of Department of Tree Improvement and Genetic Resources during 2010- 12. Seeds were collected from five mother trees each at six seed sources and progenies were raised to study the extent and pattern of variation with respect to growth and biomass characters. However, the wood samples were collected from selected trees for studying wood characters. Site S4 (Jagoti) exhibited outstanding performance for the growth and biomass characters of progenies followed by S1 (Jadh) and S5 (Katouch), whereas S3 (Jhidi) showed the lowest values for these characters. Site S6 (Andhra) trees exhibited outstanding performance for wood characters followed by S4 (Jagoti) trees. High heritability with moderate genetic gain was observed for collar diameter followed by plant height and petiole length among growth and biomass characters and high heritability with moderate genetic gain was recorded in wood density among wood characters. Highly significant and positive genotypic and significant phenotypic correlation were observed for height and diameter, fresh shoot weight and fresh root weight and dry shoot weight and dry root weight. RAPD pattern was studied using 10 primers all of which showed amplification. Fifty seven scorable bands were identified in the range size of 147.10 bp-2901.97 bp. The dendrogram generated using RAPD markers showed Jugahan-T3 as most divergent. Maximum similarity of 70 percent was observed between Jagoti-T3 and Jagoti-T2.

    MORPHOMETRIC AND CHEMICAL VARIABILITY IN SOAPNUT (Sapindus mukorossi GAERTN.) IN HIMACHAL PRADESH
    (2013) KAIRON, VINOD KUMAR; SANKHYAN, H.P.
    ABSTRACT In order to select better seed sources for improved genetic gain and quality production of Sapindus mukorossi, twenty four seed sources and two D.B.H. classes from Himachal Pradesh were evaluated on the basis of fruits and seeds morphometric traits, laboratory germination, oil content and physicochemical and progeny performance traits. The present study entitled, “Morphometric and Chemical Variability in Soapnut (Sapindus mukorossi Gaertn.) in Himachal Pradesh” was carried out in the experimental field and laboratory of the Tree Improvement and Genetic Resources, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during 2011-13. The study revealed significant variation among different seed sources for all traits, except seed viability, and oil physicochamical traits for viscosity, saponification value, specific gravity and refractive index while, all morphometric, oil content, physico-chemical, laboratory germination and progeny performance traits did not show significant variation between D.B.H. classes. Seed sources which have higher seed weight and seed diameter showed better performance than others, those seed with lower seed weight and seed diameter comparatively. Over all Banjar seed source was found to be superior followed by Garsa seed source for all traits. All traits were more over genetically controlled as revealed by high heritabilities. High heritability with low genetic advance is associated with seed diameter. Phenotypic coefficient of variability is higher than genotypic coefficient of variability for all traits which means that the characters have interacted with the environment to some degree of extent. Positive significant genotypic and phenotypic correlation was found among fruits weight, seeds weight, kernel weight, seed diameter, germination traits, oil content and progeny performance traits, which suggest that selection for any one of these, will be reliable for others too and phenotypic correlation coefficients were lower than the corresponding genotype ones for these traits.

    (2013) CHAUHAN, KANICA; SHARMA, K.R.
    ABSTRACT The present research entitled “Studies on wood characteristics using Melia azedarach L. fruits extract as a biopreservative” was carried out in the Department of Forest Products, Nauni, Solan (H.P.) and also in the Laboratory of Fruit Pathology in the Department of Mycology and Plant Pathology, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Wood samples of Pinus roxburghii Sargent, Celtis australis L., and Bombax ceiba L. of size 5cm x 2.5cm x 2.5cm +.25cm x .15cm x .15cm ( longitudinally x radially x tangentially ) were got prepared. The wood specimens of Pinus roxburghii Sargent, Celtis australis L., and Bombax ceiba L. were dipped in 0.25, 0.5, 1.0, 1.5 and 2.0 per cent (w/v) Melia azedarach L. fruits extract solution for 72 hours. These were analyzed for variation in specific gravity, per cent weight gain of treated and untreated wood on dry weight basis (Swelling), Per cent weight gain of treated and untreated wood on wet weight basis (Shrinkage), weight gain, volumetric swelling coefficient, volumetric shrinkage coefficient, Swelling and Shrinkage of wood in three different planes, Chromium absorption, Chromium leaching, chromium retention and per cent fungus growth and per cent fungal inhibition. The maximum (0.570) value for specific gravity was recorded in Celtis australis L. and minimum (0.420) in Bombax ceiba L. Swelling and shrinkage of wood were recorded maximum in Pinus roxburghii Sargent in radial and tangential plane, while in longitudinal plane, maximum was recorded in Bombax ceiba L.The minimum swelling and shrinkage were recorded in Bombax ceiba L. in radial and tangential plane while, in longitudinal plane, minimum was recorded in Pinus roxburghii Sargent. Maximum volumetric swelling coefficient was recorded in Pinus roxburghii Sargent at 1.50 per cent concentration and minimum in Celtis australis L. at 2.00 per cent concentration. The highest volumetric shrinkage coefficient was recorded in Pinus roxburghii Sargent in control while the lowest in Bombax ceiba L. at 0.25 per cent concentration. The maximum per cent variation of treated and untreated wood on dry and wet weight basis had been recorded in Bombax ceiba L. and minimum in Celtis australis L. Maximum value for chromium absorption, leaching and retention were found at 10 per cent chromic acid concentration and minimum at 5 per cent concentration. The maximum (100%) fungus colonization was recorded in control for all the species. The minimum (38.33%) fungus colonization was recorded in Bombax ceiba L. at 2.00 per cent concentration. Highest (61.67%) fungus growth inhibition was recorded for Bombax ceiba L. at 2.00 per cent concentration and the lowest for control in all the species.

    VARIATION STUDIES IN Melia azedarach Linn.
    (2013) THAKUR, SHIKHA; THAKUR, I.K.
    ABSTRACT The present investigation entitled “Variation studies in Melia azedarach Linn.” was carried out at the experimental field of Department of Tree Improvement and Genetic Resources during 2011-13. Seeds were collected from selected mother tree each at twenty seven locations and progenies were raised to study the extent and pattern of variation with respect to growth and biomass characters. Site S27 (Nauni) exhibited outstanding performance for the growth and biomass characters of progenies followed by S14 (Ropar) and S23 (Subathu), whereas S2 (Palu upper) showed the lowest values for these characters. High heritability with moderate genetic gain was observed for collar diameter followed by root length and root-shoot length ratio among growth and biomass characters while high heritability with moderate genetic gain was recorded for 100-seed weight among seed characters. Highly significant and positive genotypic and highly significant phenotypic correlation was observed for majority of the characters. However, highly significant and positive genotypic and significant phenotypic correlation was observed for root-shoot length ratio and dry root-shoot weight ratio. In case of PCA, 4 out of 17 components had eigen value greater that unity. These four components are retained for further analysis as they contribute 81.73% of total variation. RAPD pattern was studied using 17 primers of which 13 primers showed polymorphism. Ninety seven scorable bands were identified in the range size of 100 bp to 2,000 bp. The dendrogram generated using RAPD markers showed S8 (Bharmar) and S12 (Bharatgarh) as most divergent. Maximum similarity of 92 per cent was observed between S17 (Dhaulakuan) and S18 (Ghagas).
