“…In the present investigation high (>20%) genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were observed for the traits viz., number of primary branches per plant, fruit length, fruit width, fruit shape index, pericarp thickness, lycopene content, average fruit weight, fruit yield per plant and fruit yield per m 2 in the both segregating population of Cheramy RZ-F 1 and Sheeja derived F 2 population. These results are in accordance with Hazim et al (2017) [16] , Mamatha et al (2017) [27] , Rakesh et al (2018) [37] , Reddy et al (2019) [41] and Anuradha et al (2020) [5] . It indicates existence of broad genetic base, which would be amenable for further selection.…”

“…Heritability was calculated according to Weber and Moorty (1952) [56] and genetic advance as per cent of mean was estimated using the method of Johanson et al (1955). Genotypic and phenotypic correlations were calculated as per Al-Jibouri et al (1958) [5] . The direct and indirect paths were obtained according to the method of Dewey and Lu (1959) [11] .…”

“… Javed et al (2022) studied the higher PCV and GCV for yield and yield-related traits in tomato hybrids and indicated the role of genetic variability in plant selection. Understanding the nature of the inherited trait of tomatoes, whether they are phenotypic or genotypic, is essential ( Anuradha et al, 2020 ). Erazo et al (2020) investigated the higher h 2 coupled with higher genetic advance for the number of fruits per cluster (NFRC) and single fruit weight (SFW) (g).…”

Tomato is one of the most significant vegetable crops, which provides several important dietary components. Pakistan has a significant low tomato yield compared to other countries because of low genetic diversity and the absence of improved cultivars. The present study aimed to investigate the genetic variability, heritability, and genetic advance for yield and yield-related traits in tomato. For this purpose, eight tomato parents and their 15 crosses or hybrids were evaluated to study the relevant traits. Significant variation was observed for all studied traits. Higher values of the genotypic coefficient of variability (GCV) and phenotypic coefficient of variability (PCV) were recorded for yield per plant (YP) (kg) (37.62% and 37.79%), as well as the number of fruits per cluster (NFRC) (31.52% and 31.71%), number of flowers per cluster (24.63 and 24.67), and single fruit weight (g) (23.49 and 23.53), which indicated that the selection for these traits would be fruitful. Higher heritability (h2) estimates were observed for the number of flowers per cluster (NFC) (0.99%), single fruit weight (SFW) (g) (0.99%), and yield per plant (YP) (kg) (0.99%). Single fruit weight (SFW) (g) exhibited higher values for all components of variability. High genetic advance as a % of the mean (GAM) coupled with higher heritability (h2) was noted for the yield per plant (YP) (kg) (52.58%) and the number of fruits per cluster (NFRC) (43.91). NFRC and SFW (g) had a highly significant correlation with YP (kg), while FSPC had a significant positive association with YP (kg), and these traits can be selected to enhance YP (kg). Among the 15 hybrids, Nagina × Continental, Pakit × Continental, and Roma × BSX-935 were selected as high-yielding hybrids for further evaluation and analysis. These findings revealed that the best performing hybrids could be used to enhance seed production and to develop high-yielding varieties. The parents could be further tested to develop hybrids suitable for changing climatic conditions. The selection of YP (kg), SFW (g), NFC, and NFRC would be ideal for selecting the best hybrids.

High heritability in broad sense indicated that large proportion of phenotypic variance was attributable to the genotypic variance and were less influenced by environment.…”

Key fruit characters of 27 segregating variants of Oriental pickling melon (Cucumis melo var. conomon) local variety of Telangana state were assessed. Analysis of variance had shown highly significant (P=0.01) difference among variants for all the five fruit parameters, with the highest variation in average fresh fruit weight. Based on per se performance, MCHCM-26 for fruit weight, MCHCM-22 for fruit polar diameter and MCHCM-08 followed by MCHCM-22 for fruit equatorial diameter were identified as promising variants. While, for flesh thickness, MCHCM-06 and MCHCM-25 for desirable cavity diameter was scored better. Greater variability was assessed for all the five fruit traits based on per se performance in the present study. The variants can be used as parents or inbred lines for improving melon varieties. The estimates of PCV are in perfect agreement with GCV in all the characters studied indicating no influence of environment of expression of characters. High GCV and PCV (>20%) were observed for all the five key fruit traits. High heritability (>60%) was also registered for almost all the traits. Direct selection of these traits is effective for increasing the commercial fruit yield.

Genetic Variability, Heritability and Genetic Advance for Yield and Yield Attributes in Tomato (Solanum lycopersicum L.)

Abstract: The magnitude of variability and its genetic components are the most pivotal aspects of breeding material. Variability in tomato is anticipated to be immense as the fruits vary greatly in shape and size (Dixit and Dubey, 1985;Bhardwaj and Sharma, 2005). Studies
