Eight parents and their twenty-eight F1 hybrids along with the standard check (Bharat) were evaluated for thirteen yield and quality traits in bell pepper. Significant variations were noticed among all the genotypes for all the characters under study. Almost all the hybrids generated were better over one or other parent for different character studied. California Wonder x UHFBP-3 was the earliest over all the parents as well as hybrids whereas, UHFBP-3 x KC-12 was the highest yielding hybrid followed by Yolo Wonder x Nishath-1 and Solan Bharpur x Yolo Wonder. Present study suggested hybridization among diverse parents is a great way to create variability within the genus with narrow genetic base.
Genetic Parameters for Yield and Yield Components in F1 Hybrids and Parents of Bell Pepper, 2018

were evaluated for variability, heritability and genetic gain in different yield and yield
contributing traits. The data was recorded on five randomly selected plants for twelve
quantitative characters. The treatment, i.e. mean sum of squares due to genotypes showed
significant differences for twelve characters studied, indicating the presence of high
genetic variability among the genotypes. The estimates of GCV were lower than the
respective PCV, indicating the influence of environmental factors on the expression of the
traits studied. Characters like number of fruits per plant, fruit shape index, number of lobes
per fruit, pericarp thickness and fruit yield per plant showed high heritability coupled with
moderate genetic advance as percent of mean, suggesting that selection for the
improvement of these characters may be rewarding. This also indicates greater role of nonadditive
gene action in their inheritance suggesting heterosis breeding could be used to
improve these traits.

minerals and antioxidants present in them. In India systematic vegetable
improvement work was started in the 1970‟s and since then India has improved
tremendously in terms of vegetable production with respect to world ranking and
ranks 2nd after China. Almost all the varieties of public domain have been evolved
with various special characteristics through conventional breeding approach but
with the recognition of various biotechnological tools for genetic improvement of
crops, emphasis is being given on the integrated approach of vegetable
improvement. As conventional breeding approach of improvement has been
realized a slow process of genetic improvement which improves genome in an
uncontrolled fashion with more number of generations to assemble and fix the
desirable traits while, biotechnological approach allow introgression of a single
distinct gene without linkage drag. Although various biotechnological tools have
their own limitations also so present day need of improvement is based on a
multidisciplinary and coordinated approach where conventional and nonconventional
approaches will be combined.

Analysis of variance showed highly significant differences among genotypes for all the characters under study. Genotype TNBR-1 gave 44.10 and 27.70 per cent more yield over check cultivars Crimson Globe and Detroit Dark Red, respectively and also performed better for other characters. Genotype TNBR-8 and BETA-340 performed better than both the checks for total soluble solids. On the basis of results obtained in the present investigations, it was concluded that TNBR-1 proved as the best genotype for yield and other quality characters.

two check cultivars (Detroit Dark Red and Crimson Globe) were evaluated for nine horticultural traits. The
observations recorded showed that the highest number of leaves were found in genotype BETA-2221(13.41)
whereas genotype TNBR-1 recorded with highest root length (10.46cm), root diameter (76.13mm), average root
weight (336.49g), net root weight (236.52g) and yield per hectare (48.67 q/ha). Genotype BETA-2221 showed
lowest root top ratio on length basis (0.29) while genotype TNBR-8 showed lowest root top ratio on weight basis
(3.07) and non reducing sugar (14.17 %) was highest in genotype BETA-340. Maximum root yield of 448.67q/ha
was recorded in genotype TNBR-1. This cultivar also performed well for majority of other characters viz., root
diameter, root length, net root weight, flesh thickness and average root weight.

High levels of irrigation are often applied in order to maximize yields. Water and temperature are critical for producing vegetable crops, especially during winter, when the availability of water is meager and temperature falls. Studies of drip irrigation and mulch were undertaken to find the effect on different growth and yield parameters in pepper (Capsicum annuum L.) cv. Solan bharpur at Department of Seed Science and Technology, Dr. Y.S Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif 2015. The treatment comprised with eight different levels of irrigations with polythylene mulches viz., T1 = Flood irrigation, T2 = 100% Evapotranspiration through drip irrigation, T3 = 80% Evapotranspiration through drip irrigation, T4 = 60% Evapotranspiration through drip irrigation, T5 = Flood irrigation + polyethylene mulch, T6 = 100% Evapotranspiration through drip irrigation + polyethylene mulch, T7 = 80% Evapotranspiration through drip irrigation + polyethylene mulch, T8= 60% Evapotranspiration through drip irrigation + polyethylene mulch. The observations were recorded on plant height (71.50 cm) at final harvest, days to ripe fruit harvest (102.41), harvest duration (58.00), number of branches per plant (8.20), ripe fruit weight (58.87 g), ripe fruit length (7.38 cm), ripe fruit width (5.83 cm), number of ripe fruits per plant (15.67). The treatment T6 was found superior over all other treatments in terms of plant and fruit growth characters, fruit growth characters.

The experiment was laid under randomized block design with three replications at college of Horticulture, Dr Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra during Rabi season 2012-13 to investigate the genetic variability among 21 genotypes. High degree of variation was observed for all the characters studied. The difference between phenotypic (PCV) and genotypic (GCV) coefficient of variation was found to be narrow for most of the traits except bulb weight and neck thickness. The GCV ranged from 4.82 (bulb diameter) to 14.60 per cent (bulb weight) while PCV ranged from 5.72 (number of marketable bulbs per plot) to 17.29 per cent (bulb weight) for the various characters studied. The high estimates of heritability were found for all the characters studied. Expected genetic advance over mean was observed high for the characters viz yield per plot, bulb weight and number of marketable bulb per plot. These characters are therefore governed by additive gene effects. Selection on the basis of these characters will be more useful for the improvement of this crop towards attaining higher yield.
