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.

    Reproductive biology, molecular profiling and biochemical analysis of Terminalia chebula (Retz.)
    (DYSPU, 2013) Sankanur, Mahantappa; N. B. Singh
    The present investigation entitled “Reproductive biology, molecular profiling and biochemical analysis of Terminalia chebula (Retz.)” was carried out at Regional Horticultural Research Station, Jachh, Kangra and in the Department of Tree Improvement and Genetic Resources, Dr. Y. S. Parmar University of Horticulture & Forestry Nauni, Solan (HP) during 2010-2013. Reproductive biology of six T. chebulagenotypes revealed that Kothi (G 1), Paragpur 2 (G 3 ), Kallar (G4), Bhella (G 5) and Tamber (G 6 ) initiated most of their phenological events earlierthan Paragpur 1 (G 2 ) genotype. The flower buds busted after the leaves started to emerge for all the genotypes. Among genotypes each spike is on an average 6.79 ± 0.45 cm and produces 40.67 ± 3.36 flowers acropetally over a period of 6–7 days. On thebasis of sizes and development stages, the flower buds were assorted into seven different stages. The stigma protrudes out of the calyx during the mature bud stage. It is receptive since then and continues until the evening of the 3 rd day. The pollen–ovule ratio is 10,890:1. Anin-vitropollen germination percentage of freshly collectedpollen was higher in 30% sucrose with Brewbaker and Kwack’s medium (BKM). Fresh pollen viability percentages were generally high (above 70 per cent) for most of the genotypes. -20 0 C temperature with controlled humidity was found effective in long term storage of pollens for breeding programmes. The manual pollinations performed for autogamy, geitonogamy and parthenocarpy did not set fruit. Whereas, those performed for the xenogamous mode set fruit (65.76 ± 10.4%) and in open-pollinations the fruit set was 7.83 ± 0.78%. The flowers were foraged during daytime by 42 species of insects representing bees, wasps, bugs, flies, butterflies and beetles. Crossability pattern studies revealed thatgenotypes under study were cross compatible shouldbe involved in intraspecific breeding programme. In all the fourteen successful crosses between different genotypes were obtained. Per cent successful cross was highest in cross Bhella (G5) × Paragpur 1 (G 2) that was 2.14 per cent. The data for various nursery traits viz., collar diameter, plant height and number of leaves for various crosses was recorded when seedlings were 8 months old. Collar diameter for various crosses ranged between 1.36 mm to 3.38 mm. maximum value for collar diameter was recorded for cross Bhella (G5) × Kallar (G 4 ) i.e.3.38 mm. The maximum plant height was 20.80 cm which was recorded for cross Paragpur 2 (G 3) × Paragpur 1 (G2 ). The maximum number of leaves was found in the cross Paragpur 2 (G 3 ) × Paragpur 1 (G 2 ). Among the six genotypes various qualitative morphological descriptors studied viz.,crown of tree, branching type, bark colour, leaf colour, arrangement, shape, tip shape, base, margin, flower type, flower colour, fruit base and tip and seed colour did not show any variation at all except forthat fruit shape. Fruit samples collected from sixdifferent genotypes showed variation in their shapes, bases, colours, physical dimensions and chemical characteristics. Fruit shapes were of obovoid to ellipsoidal obovoid. While, the fruit base were, varied from round - broad. Fruit colour were Yellow green group – 144 A and 144 B. Fruits from Paragpur 1 (G 2 ) showed maximum values of fresh fruit weight (44.41 g), fresh pulp weight/fruit (42.08 g), fresh fruit length (6.46 cm), fresh pulp/kernel ratio (18.06) and dry pulp/kernel ratio (5.39). The present study confirms the need for domestication of T. chebulato be based on two ideotypes, one for fruit flesh [Paragpur 1 (G 2 )] and the other for seed trait [Paragpur 2 (G 3)]. Twenty five RAPD and twelve ISSR primers were effective in revealing polymorphisms among different genotypes of T. chebula. RAPD exhibited 96.76 per cent polymorphism among six genotypes, out of the total, 124 scorable bands, 120 showed polymorphism and 4 bands exhibited monomorphism. Total numbers of amplified and polymorphic fragments generated per ISSR primer revealed 97.92 per cent polymorphism among genotypes. Genotype Paragpur 2 (G 3) came as outliner as revealed by both ISSR study and combined data (RAPD and ISSR). Crossability pattern studies revealed that genotypes under study were cross compatible should be involved in intraspecific breeding programme. The overall profile of various macro and micro minerals as well as other chemical constituents shows T. chebula fruits as highly nutritious. T. chebula fruits should be regularly, used either in the raw form or in the form of 'Jams' and 'Murebba’ so that these fruits become an important part of our diet to supplement human dietary requirements.

    Studies on reproductive success of Aconitum heterophyllum under domestication
    (YSPU, 2015) Vinod Kumar; Raina, Ravinder
    The present investigation entitled “Studies on reproductive success of Aconitum heterophyllum under domestication” was carried out both in field as well as in laboratory during 2010-15. The field studies were conducted at twenty locations (10 wild and 10 domesticated) spread across different regions of Himachal Pradesh and at Medicinal and Aromatic Plants Research Farm, Shilly located at an altitude of 1550 m; Latitude N 30054’30”; Longitude E 77007’30”. The laboratory studies were conducted in the laboratory of the Department of Forest Products, College of Forestry, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). These studies were divided into six experiments namely (i) Inter-population studies on vegetative parameters under wild and domesticated conditions, (ii) Inter-population studies on floral biology under wild and domesticated conditions, (iii) Chromosomal studies ,(iv) Studies on sexual behaviour under wild and domesticated conditions, (v) Inter population studies on seed quality and germination and (vi) Molecular studies. Vegetative characters as well as tuber yield were positively impacted by domesticated conditions which makes this species amenable for cultivation. Non significant variation in seed output was observed between domesticated and wild conditions indicating no effect of domestication on seed output. Maximum seed germination of 67.78% was recorded in seed sourced from population VIID (Nichar, Kinnaur), no significant difference was noticed in seed germination amongst the domesticated and wild populations. However of the twenty wild and domesticated populations, two populations under each condition, (IW) Sisoo and (VIW) Puikar, Lahaul & Spiti under wild condition; Solang Nalla, Kullu (XD) & Sisoo, Lahaul & Spiti (IID) under domesticated conditions were found to be best on the basis of morphological as well as yield characters. Based on floral characters like flower colour, no. of sepals, colour of anthers and no. of follicles per flower, population IIW (Chansal) appears to be unique amongst all wild populations. The flowers of this polulation were dark blue coloured in sharp contrast to bluish purple in all other populations. RAPD analysis also indicated this population to be genetically unique as it formed a singlet in dendrogram. Flowers were observed to be dichogamous (protogamy) and no difference in ploidy level was observed in all studied populations (2n=2x=16). Genetic diversity among the populations was confirmed by both RAPD and ISSR markers, with some populations found to be genetically similar. RAPD analysis revealed that populations VW (Moral Danda, Shimla) and IXW (Kalatop, Chamba) are genetically similar whereas population IIW (Chansal, Shimla) formed a singlet indicating its genetic uniqueness. ISSR markers analysis revealed that populations VIIID (Topi Nalla, Chamba) and IID (Sisoo, Lahaul & Spiti) are also genetically similar. Both the marker systems have shown that populations (i.) populations VIID (Nichar) & VIIIW (Chot Kanda), (ii) populations VIIID (Topi Nalla) & IID (Sisoo), (iii.) populations VW (Moral Danda) & VID (Katgaon) are genetically closely placed, though their sites of occurrence happen to be quite far away from each other. The observations indicate suitability of Aconitum heterophyllum for domestication to be grown as a sole crop which improves its yield capacity with regard to its tuber (economic part) and seed (for propagation). The study has indicated that: i) Under domestication, the yield characters of Aconitum heterophyllum improve making it suitable for cultivation. ii) Domesticated populations like XD (Solang Nalla), ID (Shillaru, Shimla), IIID (Jagatsukh) and VIID (Nichar) were found to be the best as compared to others in terms of tuber yield. iii) No significant difference in seed yield was observed under domestication conditions indicating that domestication does not adversely impact seed production potential. iv) The population growing at Chansal (IIW), needs to be conserved as it was found to be unique on the basis of morphological as well as molecular characters.
