“…Bhandari et al (2017) reported very high heritability estimates for all traits. Moreover, our results agree with those obtained by Singh and Singh (2018), as they reported high heritability estimates for plant height, average fruit weight, TSS, number of fruits per plant, and weight of fruits per plant. On the contrary to our results, they found low heritability estimates for number of fruits per truss.…”

“…Also, Sidhya et al (2014) found medium PCV and GCV for plant height, while, in contrast to our findings, they reported medium PCV and GCV for number of fruits per plant and weight of fruits per plant. Singh and Singh (2018) agree with our results for plant height, number of fruits per truss, average fruit weight, number of fruits per plant, weight of fruits per plant, and TSS. Moreover, Saravanan et al (2019) found high PCV and GCV for number of fruits per plant.…”

“…Many researchers investigated the genetic parameters and correlation among economic traits in different breeding schemes of tomato and reported various recommendations about the utilization for such information to develop new genotypes with desirable traits (Ghosh et al, 2010;Sidhya et al, 2014;Bhandari et al, 2017;and Singh and Singh, 2018).…”

Tomato is one of the most important vegetable crops grown in Egypt. We aimed to investigate the genetic variability parameters, heritability, genetic advance, and correlation coefficient analysis for some important traits. Therefore, we evaluated the cross Ms35 × I-4, along with its parents and F2 generation, at Ad-Daljamun village, Kafr El-Zayat, Egypt, during the 2017 summer season. High genotypic coefficient of variation (GCV) was found for average fruit weight, number of fruits per plant, and weight of fruits per plant. Heritability in broad sense was very high for number of fruits per truss, number of days to 50% mature fruits, average fruit weight, total soluble solids content, number of fruits per plant, and weight of fruits per plant. The genetic advance as percentage of the mean (GA%) was high for number of flowers per inflorescence, number of fruits per truss, average fruit weight, number of fruits per plant, and weight of fruits per plant. Generally, average fruit weight, number of fruits per plant, and weight of fruits per plant, had high values of genotypic coefficient of variation, heritability, and GA%, therefore, they are important for the direct selection. The correlation coefficient analysis indicated a high association between weight of fruits per plant and average fruit weight, also, between number of fruits per plant and each of number of inflorescences per plant, number of flowers per inflorescence, and number of fruits per truss. Moreover, a high correlation was found between number of flowers per inflorescence and number of fruits per truss.

“…Similarly low amount of PCV and GCV for harvest duration and days to marketable maturity were also observed by Ara et al, (2009) and Patel et al, (2013). Kumar (2014), Singh et al, (2015) and Singh and Singh (2019) reported low phenotypic and genotypic coefficients of variation for days to 50 % flowering.…”

Tomato is an important plant grown in tropics as a perennial plant and in other areas mostly as annual plant. Tomato plant grows upto an height of 9 feet. The flowers are small, yellow and have five lobes on corolla. The fruit colour is green when unripe and red when it is fully ripe. Fruit is low in calorie and rich in vitamins and minerals. Genetic variability, heritability and genetic advance were assessed in thirty five genotypes of tomato at Departmental Research Farm of Vegetable Science, UHF, Solan, HP during kharif season, 2016. The experiment was laid out in RCBD with three replications. Analysis of variance revealed highly significant differences among genotypes for all the characters under study. The PCV (Phenotypic coefficient of variation) and GCV (Genotypic coefficient of variation) were higher for fruits per cluster (49.66 % and 49.50 %), fruits per plant (46.28 % and 46.11 %), yield per plant (38.13 % and 38.04 %) and average fruit weight (30.39 % and 30.29 %). High GCV and PCV provide the possibility of improving and fixing the characters through selection breeding. High heritability along with high estimates of genetic gain were observed for number of fruits per cluster (99.33 % and 101.63 %), number of fruits per plant (99.28 % and 94.66 %), fruit yield per plant (99.52 % and 78.18 %) and average fruit weight (99.35% and 62.19 %). High heritability and genetic gain suggest the possibility of improvement of traits by means of selection due to existence of additive gene effect. Selection for these above characters will be fruitful in improving fruit yield in tomato.

“…The mean square due to genotypes were highly significant for all traits (P < 0.01) except for days to 50% flowering, plant height, number of branches per plant, number of fruits per cluster and pericarp thickness which were significant at (P < 0.05), indicating the presence of sufficient genetic variability in the genotypes and considerable scope for their improvement Table 1. According to Asati, et al [17] analysis of variance revealed that significant differences among the genotypes for all the traits; Aysh, et al [18] reported that the highly significant differences observed among the genotypes evaluated indicates existence of a good deal of variability with respect of the characteristics assessed and offers ample chances for the genetic improvement of the tomato germplasm; Meena and Bahadur [19] reported that there were significant differences among germplasm for all the traits studies indicating the presence of significant variability in the materials which can be exploited through selection; Shankar Shankar, et al [20]; Haydar, et al [21] and Singh, et al [22] revealed that highly significant differences among the genotypes for all the characters indicating sufficient variability existed in the present material selected for the study and indicating the scope for selection of suitable initial breeding material for crop improvement; Kumar, et al [23] reported that significant differences among germplasm for all the traits studies indicating the presence of significant variability in the materials which can be exploited through selection.…”

Investigation of variability existing in crop cultivars is important to crop improvement. The study was conducted at Melkassa Agricultural Research Center (MARC) to assess the genetic variability among 36 tomato genotypes using 6*6 simple lattice designs. There were significant differences among genotypes all traits. High phenotypic and genotypic variances were recorded for number of fruits per plant, average fruit weight, fruit shape index and juice volume indicating the existence of substantial variability. High heritability along with high genetic advance as percent of the mean was exhibited by characters viz. plant height, number of fruits per plant, average fruit weight, fruit shape index and juice volume, reflecting the presence of additive gene action for the expression of these traits and selection based on them would be ideal. Generally, the present study implied the presence of genetic variability among the test genotypes with respect to the traits considered indicating an opportunity to bring about fruit yield improvements in snap bean either through direct selection or hybridization.
