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.

    MORPHOGENETIC VARIATION OF SEABUCKTHORN (Hippophae rhamnoides L.) IN SPITI VALLEY OF HIMACHAL PRADESH
    (UHF,NAUNI, 2017-12) KAIRON, VINOD KUMAR; SANKHYAN, H.P.
    ABSTRACT The study entitled “Morphogenetic Variation of Seabuckthorn (Hippophae rhamnoides L.) in Spiti Valley of Himachal Pradesh” was conducted during the year 2014-17 with the aim to evaluate morphological variation, variation in fodder quality traits, variation in physical and chemical characteristics of berries, seed oil and deoiled cake and and molecular characterization of morphovariants using RAPD of different gene pools of Hippophae rhamnoides under different gene pool areas and growing conditions. Nine gene pool areas and three growing conditions within gene pool areas selected for the study showed wide variation among different morphological, fodder quality traits, physical and chemical characteristics of berries, seed oil and deoiled cake. Morphological traits (plant height, leaf length, leaf width, leaf area, leaf density, no. of thorn, 100 fruits fresh weight, fruit diameter and 100 seed weight) differed positively significant among the gene pool areas and growing conditions, except branch length. All proximate leaf composition (100 leaf fresh weight, 100 leaf dry weight, crude fiber, crude protein and total ash) and mineral nutrient (nitrogen, potassium, calcium and magnesium) compositions showed significant difference between the gene pool areas and growing conditions for all the parameters except for leaf dry matter content and phosphorus. All physical and chemical characteristics of berries (pulp%, ascorbic acid and total sugar content), per cent seed oil, physico-chemical traits of oil (specific gravity, acid value, iodine value and saponification value) and deoiled seed cake (protein content, starch content and total sugar content) showed significant under different gene pool areas and growing conditions for all the traits, except for physical characteristics (refractive index and specific gravity) of seed oil. The RAPD fragments obtained after the amplification of genomic DNA for 27 genotypes. Total 89 RAPD markers were amplified and 71 out of 89 were found to be polymorphic in nature. The size range of polymorphic bands was 100 bp to 2,500 bp. The Jaccard's similarity correlation coefficient values ranged from 0.520 to 0.879. The highest value (0.879) was found between 87.9 per cent was found between GPA3GC1 and GPA3GC2 followed by 0.853 between GPA4GC1 and GPA8GC1 genotypes. In overall, GPA4 (Schilling) gene pool area proved to be the best among different gene pool areas on the basis of fodder quality traits. GPA3 (Sheigo) was found to be best in all gene pool areas for physical and chemical characteristics of berries, seed oil and deoiled seed cake. Among different growing conditions, GC3 (Crop Land) growing condition was found to be top ranking for most of morphological traits, fodder quality traits, and physical and chemical characteristics of berries, seed oil and deoiled seed cake. So Seabuckthorn can be used as agroforestry crop in different systems and designs. Based on the morphological variation, variation in fodder quality traits, variation in physical and chemical characteristics of berries, seed oil and deoiled cake observations it was evident that large diversity exists in naturally growing populations of Hippophae rhamnoides in the Spiti Valley of Himachal Pradesh, and this morphological variation can be exploited for the further selection of suitable genotypes to accelerate the domestication process of this important species.

    ASSOCIATION GENETICS IN POPULUS DELTOIDES
    (UHF,NAUNI, 2017-12) THAKUR, SHIKHA; THAKUR, SANJEEV
    ABSTRACT The present investigation entitled “Association genetics in Populus deltoides” was carried out in the Department of Tree Improvement and Genetic Resources, Dr Y. S. Parmar University of Horticulture & Forestry Nauni, Solan (HP) during 2013-2016. There is a collection of Populus deltoides clones procured from different countries namely USA, Australia and parts of India and maintained in the germplasm block of Naganji nursery from which ninety five clones were included in the study. Cuttings were raised in the nursery in RBD with three replications at 50 cm X 50 cm spacing and were evaluated for morphological characters in field as well as wood and molecular studies in laboratory. Analysis of variance revealed that all morphological traits were significantly different in nature. On the basis of clustering of morphological and wood traits, ninety five clones were distributed into five distinct clusters suggesting the presence of different sources of relationships amongst the clones. The gene action study revealed that additive variance was observed more than the dominance variance for most of the parameters studied except for growth traits. Growth traits expressed highly significant and positive genotypic as well as phenotypic correlation. Ninety five clones were tested for their genetic diversity using hundred SSR markers out of which ninety three gave results and sixteen ISSR markers out of which ten markers gave results. Results disclosed that dendrogram generated from ninety three SSR markers divided whole population of ninety five clones into two major clusters whereas dendrogram generated from ISSR markers depicted that whole population was divided into three major clusters. The structure analysis from SSR data revealed that the population gets divided into two sub-populations whereas from ISSR data, it was clear that the population gets divided into three sub-populations indicating the level of diversity existing in the population. On the basis of population structure analysis it is concluded that this clonal population structure is diverse. Results from genetic diversity analysis as well as STRUCUTRE analysis showed that the clustering pattern of the genotypes in STRUCUTRE analysis were almost similar to the splitting in the UPGMA tree which reveals that all the genotypes were clustered better with two clusters in SSR markers and three clusters in case of ISSR markers. Association studies of commercially important wood traits were conducted using ISSR and SSR marker data. Some important associations of markers with specific gravity of poplar wood were found in case of SSR markers whereas with ISSR markers, various associations of holocellulose and lignin content were obtained.

    ABSTRACT The present investigation entitled “Studies on Woody Species Diversity in Bhaba Valley of Himachal Pradesh” was carried out in Bhaba valley of Kinnaur district in Himchal Pradesh to study the diversity and phytosociological studies of woody species. The complete study area was divided into three altitudinal zones viz., lower (1500 -2500 m), middle (2500- 3500 m) and top zone (3500-4500m). Three sites were taken from each zone and in each site three quadrates were further laid on the basis of species area curve for measuring species diversity and phytosociological parameters. A total of 73 woody species were recorded of which 31 were trees and 42 were shrubs. The maximum species 56 were recorded in lower zone with 23 tree species and 33 shrub species followed by 36 species in middle zone with 12 tree species and 24 shrub species whereas minimum species 18 were recorded in top zone with 8 tree species and 10 shrub species, respectively. In the present study, it was observed that in total there were 73 woody species belonging to 48 genera and 27 families out of which 31 were tree species and 42 shrub species characterizing moist alpine shrub vegetation in the study area. It was further observed that Pinus wallichiana and Prunus cornuta were present in the entire valley area showing wide adaptability of these two species. The present study revealed that the dominant, co-dominant and associated species were Prunus cornuta, Betula utilis and Rhododendron companulatum in site Taudor; Betula utilis, Rhododendron companulatum and Sorbus microphyla in site Nigul; Abies spectablis, Betula utilis and Acer caesium in site Goldas; Acer caesium, Berberis lycium and Abies pindrow in site Muling; Abies spectabilis, Acer caesium and Betula utilis in site Anyar; Pinus wallichiana, Picea smithiana and Corylus jacquemontii in site Homti; Picea smithiana, Corylus colurna and Pinus wallichiana in site Kangarang; Abies pindrow, Pinus wallichiana and Picea smithiana in site Kafnu; Cedrus deodara, Pinus wallichiana and Pinus roxburghii in site Bai, respectively.

    (UHF,NAUNI, 2017-11) PURUSHOTTAM, AYATE DIPIKA; THAKUR, SANJEEV
    ABSTRACT The present study entitled “Morphological and molecular characterization of poplar (Populus deltoides) clones and development of their descriptors” was undertaken in the Department of Tree Improvement and Genetic Resources, Dr. Y.S. P. U. H. F., Nauni- Solan 173230 (H.P.) during year 2013-2016. The fifteen clones obtained from different research Institutes (locations) of India. The stem cutting of 7 inch long and 1.6 cm diameter were prepared from one year old stem cuttings and raised at a spacing of 60 cm x 60 cm in randomized block design with three replications. The three experimental sites namely 1) Dhaula kuan, RHTS, Dist. Sirmaur (H. P.), 2) Ladhowal farm, PAU, Ludhiana (Punjab) and 3) Nauni, Solan . Genotype x environment interaction studied during 2014 at studied sites gave four significant parameters in leaf blade length, mid rib length, distance between petiole junction to base of leaf and total leaf length. Therefore, stable clones obtained for leaf blade length L-621/84, mid rib length L-621/84, distance between petiole junction to base of leaf G-48 and total length of leaf L-621/84 and G-48. These clones should be tested in field. Principal component analysis gave 90.05% variability for leaf traits at three different sites. Significant Clone x Year interaction during 2013, 2014 and 2016 at Nauni was found for ratio between mid rib to maximum width of leaf parameter. Qualitative and quantitative descriptors for traits of poplar clones were prepared as per UPOV guidelines. Verification of clones on the basis of SSR markers gave 64% similarity with two sub clusters.

    REPRODUCTIVE BIOLOGY OF Bauhinia vahlii Wight. & Arn.
    (UHF,NAUNI, 2017-10) NAGAAR, BIBI; GUPTA, TARA
    ABSTRACT The present investigations entitled “Reproductive Biology of Bauhinia vahlii Wight. and Arn.” was carried out in the Department of Tree improvement and Genetic Resources, Dr. Y.S.Parmar University of Horticulture and Forestry Nauni,Solan (HP) during 2016-2017 by studying selected tree climbers of Bauhinia vahlii from two populations namely S1(Jabli) in district Solan and S2 ( Jorhji) in district Sirmour of Himachal Pradesh. The type of inflorescence is terminal corymbose raceme. The flowers are zygomorphic, bisexual, pedicellate with superior ovary. At the flowering stage calyx has three sepals one free and two partially fused which also extend the physical support to the larger petals. Corolla consists of five petals; three being larger and two smaller. Maximum anthesis was recorded as 62.66 per cent and 59.99 percent during 6.00 am to 9.00 am in S1(Jabli) and S2(Jorhji) respectively. Anther dehiscence take place 2 to 3hrs after anthesis. The initiation of stigma receptivity was observed at about 2hrs after anthesis and remain receptive up to 48hour. This species was found to be open pollinated, mostly pollinated by insect vectors. Controlled crosses were made between the trees of two sites and maximum mean pod setting was recorded in S2 (Jorhji).The pollen viability was found to be maximum from the buds, before anthesis. Pollinators were identified to be Apis indica, Apis dorsata and aphids. The individual tree variability was recorded for hundred seed weight. The tree No. S1T1 registered maximummean seed weight(138.85g) for Site1(Jabli) and in case of Site2(Jorhji) maximum mean seed weight (140.54g) was recorded from tree No.S2T4 which was at par with S2T2 and S2T5.The maximum seed germination(82%) was obtained from S1(Jabli), under glasshouse conditions. The Genetic estimates for morphometric and floral traits showed high genetic coefficient of variability and higher heritability for leaf area, pod length, ovary length, and filament length which indicates that the selection for these traits can bring about effective and desirable improvement in the species by using appropriate mating designs.
