“…Path analyses dissects the correlation into direct and indirect effects. In current study, the effect of fruit length was found to be positive on yield, although otherwise was the case in previous reports [32,33]. Leaf length negatively correlates with fruit size (fruit length and fruit width).…”

Phenotypic characterization of exotic tomato germplasm: An excellent breeding resource

Tomato production in Pakistan faces significant problems of low yields due to various biotic and abiotic stresses primarily because of a narrow genetic base of the cultivars being used. Therefore, Introduction and evaluation of the exotic tomato germplasm has become necessary to acquire elite material to develop future breeding programs. To this end, the present study was conducted for the phenotypic characterization of twenty exotic tomato genotypes along with two locally grown cultivars in semi-arid subtropical climate. Data were collected for morphological, fruit quality and fruit yield traits. A significant (p<0.05) phenotypic variation was observed for all the studied traits. Maximum yield was obtained from “Rober” i.e., 1508.31 g per plant. The maximum shelf life was observed in the Cromco, with the least weight loss (2.45%) and loss in the firmness of fruit (22.61%) in 4 days. Correlation analyses revealed a strong genetic association among morphological and yield related traits. High estimates of the heritability (ranged from 79.77% to 95.01% for different traits), along with a high genetic advance (up to 34%) showed the potential usefulness of these traits and genotypes to develop breeding programs to improve the tomato yield and fruit quality.

“…The mean squares due sca × environments were found significant for all characters except number of days to first fruit set, number of days to first fruit harvest, number of primary branches plant -1 , number of fruits cluster -1 , plant height, average fruit weight, seed yield fruit -1 and 100 seed weight. The above findings are in accordance with the findings of Dharva et al [8], Kumar et al [9], Rajkumar et al [10], Mishra et al [11], Veena et al [12], Bhajantri et al [13], Ummyiah et al [14] and Ummyiah et al [15].…”

“…Hence, these crosses with desirable SCA for maximum traits, could be selected for use in future breeding programmes i.e., hybrid development. Similar findings with respect to SCA effects were also reported by Dharva et al[8], Kaushik et al[17], Rajkumar et al[10], Veena et al[12], Veena et al[12], Mishra et al[11], Liu et al[22], Ummyiah et al…”

A study was conducted at Vegetable Research Farm, Vegetable Science Division, SKUAST- Kashmir, Shalimar, India to determine the general and specific combining abilities for maturity, growth, yield and quality traits in tomato by crossing 12 parents in a diallel Method II and Model I of Griffing mating design during Kharif season 2020. The F1 progenies of the sixty-six crosses (excluding reciprocals) were evaluated along with the twelve parents in Randomized Block Design during Kharif season 2021 at three locations. The observations were recorded on eighteen diverse traits. The analysis of variance for general combining ability (GCA) and specific combining ability (SCA) revealed significant mean squares due to GCA and SCA for all the traits under consideration. The mean squares due to GCA × environments and SCA × environments were found significant for most of the characters. None of the parents possessed significant and desirable GCA for all the traits. Different parents were found to reveal desirable general combining ability for different traits. Similarly, none of the crosses possessed significant and desirable specific combining ability for all the traits. However, different crosses were found to reveal desirable SCA for different traits.

“…Number of flowers per cluster, number of fruits per cluster, fruit width, plant height and days to first flowering and number of primary branches per plant had association with other traits (Table 6). These findings are in accordance with the findings of of Younis et al (2000) [58] , Lakshmikant and Mani (2004) [25] , Raut et al (2005) [39] , Mayavel (2005) [29] , Sharma et al (2009) [48] , Livia et al (2012) [26] , Kumar et al (2015), Lakshmi et al (2017) [24] , Mishra et al (2019) [31] , Reddy et al (2019) [41] and Sangamesh (2019) [46] . Thus, suggesting the possibility of simultaneous selection for these traits for improving yield in the respective segregating populations.…”
