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.

    The present investigation entitled, “Mapping of fruit crop diversity and frost vulnerability using geo spatial tools in Bilaspur district” was carried out at Geoinformatics laboratory, Department of Fruit Science, College of Horticulture and Forestry Neri, Hamirpur (HP) during 2017 to 2019. IRS P6 LISS IV data of November and December were used to monitor and estimate acreage under different fruit crops. The ground truth sites were used as training sites to generate spectral signatures using LISS IV data. The data were analyzed using ArcGIS 10.5.1, MS office & Excel 2007. Total area under mango in district Bilaspur was obtained as 4116.12 ha in 20172018. Out of total mango area i.e 4116.12 ha. Sadar block with 1501.91 ha is the highest mango holding block followed by Jhandutta. Swarghat block in the district Bilaspur has lowest mango area 472.12 ha. In case of citrus, total area was obtained as 1394.91 ha. Out of total citrus area, Ghumarwin block with 512.34 ha is the highest holding block followed by Jhandutta. Sadar block in district Bilaspur has lowest citrus area 205.42 ha. In study area litchi occupy an area of 642.68 ha. Out of total area, Sadar block with 251.42 ha is the highest litchi holding block followed by Ghumarwin. Swarghat is the lowest litchi holding block in study area. The research mapped frost hotspots in the district Bilaspur were identified by establishing the trend of minimum temperature occurrences between the years 2004-2018. Frost is categorized into three categories i.e severe frost (≤1℃), moderate frost (2-3 ℃) and minor frost (4℃) in which the identified probable severe areas are along Berthin, Talai and Talari in Jhandutta block and Brahmpukhar, Namhol, Dehak and Ghagas in Sadar block. The change in the area and production of fruit crop in district Bilaspur from 1997-2018 were analyzed. The study shows that district Bilaspur has undergone a significant change in cropping pattern of fruits. Total area of fruits was increased by 17.08% in case of production it is increased by 110%.

    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-12-14) RAHI, LAKESH; SHARMA, VIKAS KUMAR
    The present investigations entitled, “Morpho-molecular characterization, evaluation and hybridization among different cultivars of guava (Psidium guajava L.)” were carried out at farm of Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur (HP) during 2018 to 2019. Significant variations were observed among seven guava genotypes for various quantitative and qualitative traits. Cultivar Shweta had maximum fruit length, weight, fruit length/width ratio, pulp weight, leaf width, thickness of outer flesh, high vitamin C content and minimum number of seeds per fruit. In variability studies, high heritability (>60%) was observed for all the characters and seed weight had maximum phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV).High genetic advance coupled with high genetic gain was recorded in number of seeds per fruit, seed weight, thickness of outer flesh and total soluble solids (TSS). In correlation studies, average fruit weight had positive and significant correlation with fruit length and fruit width at phenotypicandgenotypic level. The path coefficient analysis showed that the average fruit weight had maximum positive direct effects on seed weight followed by fruit width and fruit length. The maximum negative direct effects of number of seeds per fruit followed by core diameter weregoverned on average fruit weight. In diversity study 42 RAPD markers were screened to estimated genetic diversityamong guava cultivars. Only 12 primers were able to amplify and yielded 48 scorable bands in all seven-guava cultivars out of which 41 bands were polymorphic with 85.42% polymorphism, which depicts high level of polymorphism among the cultivars under study.The similarity coefficient value ranged from 0.117 to 0.670. In RAPD Cluster analysis two major Clusters are formed and Cluster ‘I’ was found to be bigger Cluster containing five cultivars and Cluster ‘II’ containing two cultivars. Further, sub clustering in Cluster ‘I’ Allahabad Safeda was away from the cluster at approximately 35 % similarity, while Shweta and Lucknow-49 were found very close with 69% similarity in cluster ‘I’. In hybridization study among guava genotypes, the highest fruit set percent in ten crosses was observed in cross Allahabad Safeda × Lalit (68.33%) followed by cross Shweta × Lalit (66.67%) and Lucknow-49 × Lalit (61.67%). No fruit set was observed in crossArkaAmulya × Lalit.

    (2019-10-25) SHARMA, RAHUL; SHARMA, SOM DEV
    The present investigation entitled, “Morpho-molecular characterization and hybridization among different cultivars of Pomegranate (Punica granatum L.)” was carried out at Regional Horticulture Research and Training Station Bajaura, Kullu (HP) during 2017 to 2019.A significant and wide range of variation was observed among genotypes for various quantitative characters. In variability study, total aril weight had maximum phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) followed by pollen viability (%). High heritability (>60%) was recorded for all the characters. High genetic advance coupled with high genetic gain was recorded in total aril weight, pollen viability, septum thickness, fruit weight, rind thickness, crown length and leaf blade width. Jodhpur Red recorded maximum calyx length, calyx ratio (l/w), petal length, fruit length, fruit width, fruit weight, aril width, seed width and medium soft seeded. Phenotypic and genotypic correlation coefficients showed that fruit weight had positive and significant association with calyx length, fruit width, crown length, aril length and septum thickness. The fruit weight had negative and significant association with leaf blade width. The path coefficient analysis has shown that the fruit weight had maximum positive direct effect on fruit width followed by total aril weight. The maximum negative direct effect of pollen viability followed by aril length was observed on fruit weight. Genetic diversity among the pomegranate cultivars was estimated by 41 RAPD markers. Only 8 primers out of total of forty one primers yielded scorable bands. A total of 41 bands were amplified in all the eight cultivars and 80.49% polymorphism was obtained. This showed the high level of polymorphism present in eight pomegranate cultivars under study.The similarity coefficient value ranged from 0.000 to 0.536. Dendrogram divides all the cultivars in one cluster and Chawla was separated as a singlet. Further, two subclusters were formed and comprises of three cultivars in each of them. In hybridization study of pomegranate genotypes, the highest fruit set percent in sixteen crosses was observed in cross Mridula × P-26 (77.80%) followed by cross Bhagwa × P-26 (66.70%) and G-137 × Chawla (36.10%). No fruit set was observed in crosses Bhagwa × Nabha and Bhagwa × Chawla.

    (COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 2019-12-14) SHARMA, ROHIT; KUMAR BANYAL, AJAY
    The present investigation entitled “Studies on the effect of summer pruning on cropping behaviour in low chill peaches (Prunus persica L. Batsch.)” was carried out in the Experimental orchard of Department of Fruit Science, College of Horticulture and Forestry, Neri, Hamirpur (HP) during the year 2018 and 2019. The studies were conducted in two experiments on 3-year-old low chill peaches cvs. Early Grande, Florida Prince and Shan-i-Punjab, planted at a spacing of 2 x 2 m 2 and trained to Pillar system. In the first experiment, effect of summer pruning intensities viz., T 1 (control), T 2 (20% summer pruning+ WP), T 3 (30% summer pruning+ WP), T 4 (40% summer pruning+ WP), T 5 (50% summer pruning+ WP), T 6 (60% summer pruning+ WP) and T 7 (standard winter pruning) on cropping behaviour were studied in peach cv. Early Grande. Whereas, In the second experiment, summer pruning treatments at different times viz., T 1 (control), T 2 (25% summer pruning on July10 th +WP), T(25% summer pruning on July 20 th 3 +WP), T 4 (25% summer pruning on July 30 th +WP), T(25% summer pruning on August 10 th 5 +WP) and T 6 (standard winter pruning) were tried in peach cvs. Florida Prince and Shan-i-Punjab to see the effect on cropping behaviour. During the present investigations, the results obtained showed that among different pruning intensities, the best results in terms of vegetative, reproductive and qualitative characteristics were obtained with severest pruning intensity i.e. T 6 (60% Summer Pruning + WP). Although, the fruit yield was slightly lower, but quality of fruits was much superior than other treatments. In case of summer pruning performed at different timings, the best results in terms of vegetative, reproductive and qualitative parameters were recorded with earliest summer pruning i.e. T 2 (25% summer pruning on July 10 th + WP) treatment. However, among cultivars, Florida Prince performed better than Shan-i-Punjab.

    ABSTRACT The present investigation entitled “Studies on genetic in apple (Malus × domestica Borkh.)” was carried out at Regional Horticultural Research and Training Station Bajaura, Seobagh (HP) during 2018-2019 with the objective of studying the variability in different apple cultivars and to assess the association among yield and other traits for quantification of promising cultivars for future use. Twelve cultivars of apple namely, Red Chief, Vance Delicious, Oregon Spur II, Super Chief, Scarlet Gala, Gale Gala, Red Delicious, Top Red, Scarlet Spur Red Delicious, Early Red One, Red Fuji and Gold Spur were evaluated for their plant growth, floral, fruiting and chemical characteristics. Analysis of variance showed significant differences among all the genotypes for all the characteristics under study viz., tree height, tree spread, trunk girth, annual shoot growth, tree volume, leaf area, bud burst, first flower open, full bloom, petal fall, duration of flowering, fruit shape, bearing habit, fruit colour, fruit set, fruit drop, fruit length, fruit breadth, fruit weight, fruit volume, yield per tree, yield efficiency, total soluble solids, fruit firmness, titratable acidity, sugaracid ratio, total sugars, reducing sugars and non-reducing sugars. The genotypes Scarlet Spur Red Delicious followed by Red Chief, Super Chief were found promising for fruit length, fruit breadth, fruit weight, fruit volume, titratable acidity and non-reducing sugars whereas Red Delicious V-22 was found promising for yield per plant (kg). A high phenotypic and genotypic coefficient of variation was recorded for tree volume. High heritability coupled with high genetic gain was obtained for trunk girth, tree spread, tree volume, titratable acidity, non-reducing sugars sugaracid ratio, fruit volume, fruit set and fruit drop. High heritability coupled with moderate genetic gain was obtained for leaf area, total soluble solids, total sugars, reducing sugars, fruit weight and fruit firmness, thereby indicating selection of these traits for crop improvement. A highly positive and significant correlation coefficient of yield per plant was observed with annual shoot growth followed by tree height, trunk girth, tree spread, tree volume and leaf area at both phenotypic and genotypic levels. Maximum positive direct effect cited towards yield were contributed by tree height followed by average leaf area, trunk girth, fruit firmness, yield efficiency, fruit breadth, tree spread, fruit weight, fruit volume and duration of flowering

    ABSTRACT The present investigation entitled “Influence of seaweed extract on growth, yield and quality of kiwifruit [Actinidia deliciosa (A. Chev.) C.F. Liang & A.R. Ferguson]” was carried out in kiwifruit block of Department of Fruit Science during the year 2018. Nine years old kiwivines cv. Allsion of uniform size and vigour, planted at 4m × 6m spacing were selected for studies. The experiment was laid out in Randomized Block Design with 11 treatments viz; T1 (SWE Spray @ 1000 ppm at FS), T2(SWE Spray @ 2000 ppm SWE at FS), T3(SWE Spray @ 3000 ppm at FS), T4(SWE Spray @ 1000 ppm at FS and 10 DAFS), T5(SWE Spray @ 2000 ppm at FS and 10 DAFS), T6(SWE Spray @ 3000 ppm at FS and 10 DAFS), T7(SWE dip @ 1000 ppm 10 DAFS),T8(SWE dip @ 2000 ppm 10 DAFS),T9(SWE dip @ 3000 ppm 10 DAFS),T10(CPPU dip @ 5 ppm 10 DAFS) and T11 [Control (Untreated)]. The present investigation compared different seaweed extract treatments, applied at different time and concentration with CPPU and untreated control. The highest increase in fruit length and fruit diameter in developing kiwifruit was recorded with T9(SWE dip @ 3000 ppm 10 DAFS) which was non-significant with CPPU treatment and wassuperior to control. The average fruit length, fruit diameter, average fruit weight, fruit firmness and total fruit yield were also found to be the highest with the same treatment. Fruit quality parameters namely fruit TSS and total sugars were recorded maximum with T6(SWE Spray @ 3000 ppm at FS and 10 DAFS). The TSS:acid ratio and reducing sugars were recorded highest with T9(SWE dip @ 3000 ppm 10 DAFS). The treatment T8 (SWE dip @ 2000 ppm 10 DAFS) was found to advance the harvesting maturity by 6 days and this treatment also exhibited lowest physiological loss in weight (% PLW) with highest ascorbic acid content. After 15 days storage at ambient room temperature (25±2oC), the treatment T9 (SWE dip @ 3000 ppm 10 DAFS) recorded highest TSSacid ratio and the lowest titratable acidity.

    (UHF,NAUNI, 2019-10) POOJA, KUMARI; POOJA, KUMARI; CHAUHAN, NEENA; CHAUHAN, NEENA
    ABSTRACT The present studies entitled “Standardization of budding techniques for propagation of sweet cherry (Prunus avium L.) was conducted at Regional Horticultural Research and Training Station, Mashobra, Shimla, Dr YS Parmar University of Horticulture and Forestry, Nauni-Solan, Himachal Pradesh, during the year 2018-2019. The study consisted of four budding methods viz, chip budding, shield budding, annular budding and patch budding as main plot treatments and nine budding dates viz, 15th May, 30th May, 14th June, 29th June, 14th July, 29th July, 13th August, 28th August and 12th September as sub plot treatments. The experiment was laid out in Split Plot Design and was replicated four times. The results revealed that amongfour methods of budding, chip buddingrecorded maximum bud-take success (52.21 %), linear growth of scion (67.97 cm), number of feathers (2.42), length of feathers (8.17 cm), number of internodes (12.40), internodal length (4.00 cm) and percentage of saleable plants (59.80 %). Among different dates of budding, plants budded on 12th September recorded maximum values for different growth parameters like linear growth of scion (79.45 cm), radial growth of scion (9.47 mm), number of feathers (2.82), number of internodes (13.24) and proportion of saleable plants (72.92 %) but the bud-take success on this date was very low (19.00 %). Whereas, plants budded on 30th May recorded highest per cent sprouting (83.00 %) and maximum bud-take success (68.99%) and values recorded for growth parameters like linear growth of plant (66.18 cm), radial growth of scion (7.52 mm), number of feathers (1.84), number of leaves (53.16), leaf area (23.37 cm2) and length of internodes (3.94 cm) during 15th may and 30th May were also appreciable. Thus, taking the budding success and proportion of commercial grade plants into consideration, chip budding performed during 15thMay and 30thMay can be recommended for cherry propagation.

    EVALUATION OF SELECTED PEACH (Prunus persica L. Batsch) CULTIVARS
    (UHF,NAUNI, 2019-10) THAKUR, ANKIMA; CHAUHAN, JITENDER K
    ABSTRACT The present study titled, “Evaluation of selected peach (Prunus persica L. Batsch) cultivars” was carried out during 2018-2019 at the Model farm, Directorate of Research, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP). Seven peach cultivars viz. ‘Andros’, ‘Glohaven’, ‘Paradelux’, ‘Pratap’, ‘Redhaven’, ‘Shan-i-Punjab’ and ‘Suncrest’ was evaluated for their tree, foliage, floral and fruit characteristics and to studythe variability, heritability, correlation and path analysis of different characters. Wide range of variability was observed among all the cultivars for different plant characters. On the basis of overall mean performance, the cultivar ‘Pratap’ has been found promising for better fruit quality followed by cultivar ‘Shan-i-Punjab’. However, regarding yield characteristics cultivar ‘Redhaven’ was found best. High heritability coupled with high genetic gain was observed for characters like tree volume, trunk girth, fruit weight, fruit volume, pulp weight, pulp/stone ratio and yield. While, high heritability coupled with moderate genetic gain was obtained for characters like tree height, fruit length, fruit length/diameter ratio, specific gravity, total soluble solids, reducing sugars and stone weight, indicating predominance of additive gene action in the inheritance of these characters, hence selection would be effective for genetic improvement of said characters in desired direction. The correlation studyrevealed significant and positive correlation of yield with leaf blade width and titratable acidity at phenotypic and genotypic level, respectively. Highest direct positive effects toward yield was contributed by fruit length, fruit weight, fruit set, total sugars, total soluble solids, tree volume, leaf blade length, pulp/stone ratio, leaf blade width and fruit firmness, hence could be given due weightage during selection process for yield improvement of selected peach cultivars.
