Abstract

Morphological characterization of bell pepper (Capsicum annuum L. var. grossum Sendt.) germplasm is a prerequisite in any crop improvement programme. The present study was conducted in 2015 at the Vegetable Experimental Farm of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to evaluate morphological traits of bell pepper genotypes in 43 F₅ progenies, one susceptible and two resistant checks. Characterization of genotypes was done for the plant descriptors that included fruit shape, fruit shape at pedicel attachment, blossom end fruit shape, fruit position, plant height and fruit colour. Blocky fruit shape, truncate/ cordate fruit shape at pedicel attachment, sunken blossom end fruit shape, pendent/ erect fruit position and dark green fruit colour at the time of horticultural maturity were the desirable horticultural attributes from consumer's point of view. Bell pepper germplasm contains sufficient genetic variability and can be used for crop improvement. Among the evaluated genotypes, 14 had blocky fruit shape, 12 with lobate fruit shape at pedicel attachment, 25 with sunken blossom end fruit shape, 7 with upright fruit position and 28 genotypes with plant height of 46-65 cm. Green and yellow green coloured fruits were prominent. 27, 9 and 10 progenies were categorized under green group, yellow yellow green group and yellow green green group, respectively. Characterization of bell pepper germplasm will provide valuable information for strengthening breeding programmes because it helps in selection of parents on the basis of morphological characters. P-43, P-24, P-25, P-33, P-34, P-10, P-23 were the progenies with desirable horticultural attributes and can be used for their exploitation in future breeding programme.

Abstract

Forty six genotypes of bell pepper were evaluated during the summer rainy season of 2015 at CSKHPKV, Palampur to study the extent of genetic variability, determine the association between different characters, understand the direct and indirect effects of component traits on marketable fruit yield, and identify desirable genotypes. Sufficient genetic variability was observed for all horticultural traits studied; that is, days to 50 per cent flowering, days to first picking, plant height, primary branches per plant, harvest duration, fruit length, fruit width, pericarp thickness, lobes per fruit, average fruit weight, fruit yield per plant, fruits per plant, marketable fruit yield per plant and marketable fruits per plant. On the basis of mean performance, the progenies P-30, P-39 P-33, P-11 and P-28 were the highest yielder. The phenotypic coefficient of variation (PCV) indicated higher values than genotypic coefficient of variation (GCV) for all the traits, indicating close association between phenotype and genotype. High heritability estimates along with high genetic advance were recorded for average fruit weight, fruit yield per plant and marketable fruit yield per plant indicating the role of additive gene action for their inheritance. Harvest duration and fruit width had high heritability estimates along with low genetic advance, indicating non-additive gene activity, and these could be improved through hybridization The maximum direct effect on marketable fruit yield per plant was exhibited by marketable fruits per plant, average fruit weight and fruit width, whereas days to 50 per cent flowering and marketable fruits per plant had negative direct effects. Adequate genetic variability was present within bell pepper germplasm to aflow breeding improvement of marketable yield.

Abstract

Present investigation was carried out for two successive years i.e. 2016-17 and 2017-18 to study the performance of grafted tomato with respect to growth, yield and quality of tomato under polyhouse conditions at Department of Vegetable Science and Floriculture, CSKHPKV, Palampur. Sixteen different ischolar_mainstocks of tomato were grafted with scion cultivar 'GS-600'. The experiment was laid out in a Randomized Block Design with three replications and cleft grafting method was used. Plants grafted on ischolar_mainstock LS-89 proved superior to other ischolar_mainstocks for days to first flowering and days to first harvest. For prolonged harvest duration plants grafted on tomato ischolar_mainstock Green Gourd found superior. Higher yield in terms of number of marketable fruits per plant, marketable fruit yield per plant and marketable fruit yield per square metre in were recorded plants grafted on tomato ischolar_mainstock Green Gourd.
