    Assessment of Genetic Divergence in Chilli (Capsicum annuum L. var. acuminatum) Genotypes in mid hilly regions of Uttarakhand
    (College of Horticulture, Bharsar Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2017-07) SILARU, RAGHUVEER; Pant, S.C. (Dr.)
    The present investigation entitled “Assessment of Genetic Divergence in Chilli (Capsicum annum L. var. acuminatum) Genotypes in mid hilly regions of Uttarakhand” was carried out at the “Vegetable Research cum Demonstration Block”, College of Horticulture, VCSG UUHF, Bharsar, during Kharif, 2016 to evaluate diverse germplasm of Chilli. The experiment was laid out in a RCBD with three replications. In this study, nineteen genotypes were evaluated for different horticultural traits Madhya Pradesh local, Bydagi kaddi, Hill local and Sankeswar recorded highest fresh fruit yield and also performed better for other horticultural traits. Bydagi kaddi, Varadha, Sankeswar and Hill local, recorded highest dry fruit yield and also performed better for other horticultural traits than check cultivar. Genetic analysis indicated that phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) in all of the attributes studied. The phenotypic and genotypic coefficients of variation were found high for almost all the traits except plant stem girth, days to first flowering, days to 50% flowering and capsaicin. High heritability estimates coupled with high genetic gain were observed for almost all the traits studied except plant height, plant stem girth, days to 50% flowering and capsaicin, which indicated that these traits are under additive gene effects and are more reliable for effective selection. Linear correlation analysis showed that dry fruit yield per plant had positive and significant correlation with number of tertiary branches per plant, total number of branches per plant, days to 50% flowering, fruit length, fresh fruit yield per plant, fresh fruit yield per plot, fresh fruit yield per hectare and seed weight per fruit were significantly and positively associated with yield both at genotypic and phenotypic level. Hence, there traits should be taken into consideration, while making the selection for yield improvement in chilli. Path coefficient analysis revealed that dry fruit yield per plant followed by number of fruits per plant, total number of branches per plant, pericarp thickness, fruit length, fresh fruit yield per hectare, plant stem girth, number of primary branches per plant, chlorophyll ‘b’ content and seed weight per fruit had positive direct effect on dry fruit yield per plant. Further, on the basis of D2 analysis these genotypes were grouped into five divergent clusters and divergence between cluster V and II is found to be maximum, therefore superior cross combinations are expected to be obtained in future breeding Programmes by crossing between the genotypes of these clusters. Environment and its interaction with the genotypes were observed to be significant for all the traits in the present study. Therefore, environments have significant impact over the performance of the genotype.

    GENETIC EVALUATION OF MARIGOLD GERMPLASM (TAGETES SPP.) FOR GROWTH, YIELD AND QUALITY PARAMETERS UNDER BHARSAR CONDITIONS
    (College of Horticulture, Bharsar Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2017-07) POULOSE, BIBIN; Paliwal, Ajaya (Dr.)
    The present experiment was conducted at Vegetable Research and Demonstration Block of the Department of Vegetable Science, Veer Chandra Singh Garhwali Uttarakhand University of Horticulture and Forestry, Bharsar, Pauri Garhwal during summer season of 2016 on 21 genotypes of both African and French marigold to estimate the genetic variability, heritability, genetic advance and correlation of various traits with yield. The observations were recorded on growth, flowering and yield parameters. The analysis of variance revealed that the mean sum of squares due to genotypes were highly significant for all the characters studied, indicating a wide range of variability in the material investigated. The highest yield per plant was recorded in the genotype Coimbatore Local followed by Pusa Narangi and the lowest in genotype BC-3. The high GCV and PCV values were observed for plant height, number of days for first flower bud initiation, number of flowers per plant, number of ray florets per flower, fresh weight of the flower and yield per plant. In the present study the characters, yield per plant, number of ray florets per flower, number of flowers per plant, number of leaves per plant and plant height showed high heritability along with high genetic gain. Association analysis revealed a highly significant positive correlation of flower yield per plant with plant height, plant spread, number of primary branches, number of leaves per plant, stem diameter, fresh weight of flower, flower diameter, number of ray florets and flowering duration, indicating selection for these characters may help in crop improvement. Path analysis depicted that the characters like fresh weight of the flower and the number of flowers per plant are important characters affecting flower yield since they had a high positive direct effect. Based on D2 values, all the 21 genotypes were grouped into 5 clusters, indicating the presence of a considerable amount of genetic diversity among the genotypes under study

    Evaluation of chrysanthemum (Dendranthema grandiflora Tzvelev.) genotypes under hilly regions of Uttarakhand
    (College of Horticulture, Bharsar Campus, V.C.S.G. Uttarakhand University of Horticulture and Forestry, 2017-08) S., PRASHANTH; Punetha, Parul (Dr.)
    The present investigation was carried out at Floriculture and Landscaping Block, College of Horticulture, VCSG, UUHF, Bharsar, Pauri Gharwal (Uttarakhand) during the year 2016-2017, with 15 genotypes in the Randomized Block Design, with three replications. Observation was made for vegetative, floral, quality and yield parameters. Data were analyzed to study the mean performance, extent of variability, heritability and character association for different parameters. Results revealed that among the vegetative characters, genotype Punjab Anuradha recorded maximum plant height (79.28 cm), plant spread (49.44 cm), numbers of primary branches (19.13), secondary branches (30.13) and number of leaves per plant (373.04), Genotype White star recorded highest leaf area (23.98 cm2). Among the floral characters, significant variations were observed among the genotypes, Genotype Punjab Anuradha recorded early flower bud initiation (62.13 days), minimum days taken for 1st harvesting (88.89 days), whereas genotype Dolly white recorded minimum days taken for 50% flowering (89.21 days), Genotype Ajay recorded minimum days taken for 100% flowering (101.80 days) and the genotype White Bouquet had longest duration of flowering (62.61 days). In case of yield and quality parameters, Genotype White star recorded highest yield per plant (10.56 kg) and highest flower weight (7.47 gm), with maximum vase life (19.67 days) and shelf life (10 days). Genetic analysis indicated that phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) in all of the attributes studied. The phenotypic and genotypic coefficients of variation were found highest for yield per plot (kg), weight of flower (gm), number of flowers per plant, stalk length (cm), number of secondary branches and shelf life (days). Highest heritability coupled with highest genetic advance was seen in number of leaves per plant, whereas, highest heritability coupled with genetic gain was seen in weight of flower (g). In genotypic and phenotypic correlation, significantly positive correlation was found with plant height (cm), plant spread (cm), number of primary branch, number of secondary branch, number of leaves per plant, leaf area (cm2) and number of flower per plant, whereas, in genotypic and phenotypic path coefficient analysis, it is found that number of leaves per plant has direct positive effect on yield per plot. Thus, from the present investigation it can be concluded that out of 15 genotypes, Punjab Anuradha, White Star, Pusa Centenary and White Bouquet were found highly suitable for commercial cultivation under the hilly regions of Uttarakhand.
