“…Number of fruits directly affects the total fruit yield per plant, so this character is very important for fruit yield. These findings are in close agreement with (Dundi and Madalagaeri,1991;Kumar et al,2006;Asati et al,2007;Saleemet al,2009;Kumari and Sharma ,2011;Shankar et al,2013;Solieman et al,2013;Madhaviet al,2013;Syarifah et al,2016;Savita and singh,2017;VRamana et al, 2018;and Pramod et al,2019). Midparent heterosis of total fruit yield ranged from -4.65 percent (P4xP5) to 11.55 percent (P1xP5) and better parent heterosis from -3.55 percent (P1xP4) to 7.08 percent (P1xP5).Total fruit yield per plant is the most important trait which deserve highest consideration in any breeding program.…”

“…(Singh et al, 2005;Asati et al, 2007;and Singh and Asati, 2011) also reported positive heterosis for average fruit weight in tomato. Similar results were also obtained by (Dod et al,1995;Kumar et al, 2009;Kumari and Sharma, 2011;Shankar et al, 2013;Solieman et al,2013;Madhavi et al, 2013;Syarifah et al,2016;Vramana et al,2018;and Pramod et al,2019). Heterosis for number of Fruits / plant was found in a range of -25.63 % (P 4 x P 5 ) to 13.97 % ( P 1 x P5) for mid parent and -13.76 % ( P2 x P5) to -40.21 % ( P4 x P5 ) over better parent .…”

“…Singh and Asati (2011) also noticed heterosis in favorable direction. Heterosis range (-29.13 to 33.26%), was reported by (Kumari and Sharma, 2011;Shankar et al, 2013;Solieman et al, 2013;Madhavi et al ,2013;Syarifah et al, 2016;Savita and singh, 2017;Vramana et al, 2018 andPramod et al,2019). Heterosis for number of branches/ plant was found in a range of -33.29 % (p 3 x P 5 ) to 47.57 % (P 1 x P 3 ) over mid parent and -20.68 % (P 4 x P 5 ) to 40.93 % (P 1 x P 3 ) over better parent.…”

The present experiment was performed to classify best combiner parents and cross combinations for developing accomplished hybrids for yield and quality components in tomato, using half diallel analysis for five parents and ten hybrids including; Super Marmande, Peto 86, Super strain B, Edkawy and Red Star. The results indicated that heterosis over high parent gave significant values in most crosses. The combinations of good combiner parental cultivar and best hybrids for each character were estimated according to the best GCA and SCA. Specifically, all the studied traits showed highly significant GCA and SCA values. Therefore, additive and non-additive gene actions were vital in the expression of these traits. Concerning general combining ability, it was found that ̔ Red Star̕ was the best combiner for plant height, number of branches, fruit length, number of fruit locules, and total fruit weight;̔ Peto 86̕ for leaf area index, fruit shape index and number of fruits per plant, ̔ Super strain B ̕ for T.S.S. and total fruit yield, and ̔ Edkawy̕ for number of leaves, fruit diameter, number of fruit locules and average fruit weight. The cross P1xP2 was found to be the best combination for plant height, (P1 x P3) for number of branches/ plant, (P2 x P5) for No. of leaves / plant, (P 1 x P 5) for total fruit yield and number of fruit per plant, (P 2 x P 3) for fruit shape index and leaf area index ,(P2 x P4) for fruit weigh/ plant, (P2 x P5) for fruit length and number of leaves / plant, (P3 x P4) for fruit diameter, (P3 x P5) for number of fruit locules and (P4 x P5) was the best combination for T.S.S. Effects of additive gene appeared to be more important than non-additive gene effect as reflected on plant height, No. of leave, fruit length, fruit diameter, T.S.S, No. of fruit locules, average fruit weight, No. of fruit / plant, and total fruit weight. However, it was found that nonadditive gene effect appeared to play important roles than additive effect for No. of branches and fruit shape index. In addition, both broad and narrow sense heritability values were high for all studied traits, indicating that all traits were highly heritable.

“…The cross VRT-18×H-86 exhibited the highest significant negative standard heterosis at -21.50% followed by VRT-50×SEL-7 at -16.53% and VRT-50×H-86 at -13.90%. Negative heterosis for the trait days to 50% flowering is observed by Hannan et al (2007) [4] , Islam et al (2010) [5] , Ahmad and Quamruzzaman (2011) [6] , Kumar et al (2012) [7] Khan and Jindal (2016) [8] , Ramana et al (2018) [9] and Sah et al (2020) [10] in tomato. With regards to plant height, VRT-51×SEL-7 (44.5%) displayed the highest level of significant positive relative heterosis followed by H-24×H-86 (41.63%) and VRT-74×SEL-7 (34.47%) as indicated in Table 1.…”

The experimental material consisted of 13 genotypes, including 10 lines, 3 testers, and one standard check (Pant T1). These genotypes were chosen based on their performance for various traits. A Line Tester design was used to evolve 30 F1s and 30 F2s from these 13 genotypes. An investigation was conducted on the three growth parameters, specifically Days to 50% flowering, plant height, and number of primary branches per plant, to examine heterosis and inbreeding depression. The cross VRT-18×H-86 exhibited the highest significant negative mid-parent, better parent, and standard heterosis for days to 50% flowering, which is advantageous in terms of early flowering. Additionally, it displayed the lowest level of inbreeding depression. The cross VRT-51×SEL-7 exhibited the highest level of heterosis in terms of plant height, with a significant magnitude of 44.50%. On the other hand, the cross H-24×SEL-7 displayed the lowest level of inbreeding depression, with a magnitude of 17.48%. When examining the number of primary branches per plant, we found that Kashi Aman×SEL-7 exhibited the highest level of heterosis at 48.40%. On the other hand, the cross VRT-01×ToLcv-41 showed the lowest level of inbreeding depression at -35.35%, which is quite desirable. These findings suggest that these specific crosses have the potential for further selection in varietal development programmes.

This study was conducted to estimate heterosis for the yield and yield contributing traits of 32 cross combinations involving 12 diverse lines of some Bangladeshi tomato genotypes considering line x tester mating fashion at the experimental field of Sher-e-Bangla Agricultural University, Dhaka in 2016-2017 and 2017-2018 winter season. The experiment was designed in a Randomized Complete Block Design (RCBD) with three replications. The analysis of variance (ANOVA) showed highly significant difference for all the characters suggesting the presence of genetic variability among the studied materials. Four cross combinations (L1xT1, L3xT2, L3xT3, L5xT1) showed desirable negative significant heterosis for days to first flowering in both relative heterosis (RH) and heterobeltiosis (HB) ranged from -2.56% to -19.05%, respectively. Highest positive significant heterosis in both RH and HB was observed in four crosses L4xT4 (63.48% and 48.25%), L5xT2 (46.77% and 46.27%), L5xT4 (62.58% and 34.78%) and L8xT3 (37.39% and 35.12%) for individual fruit weight (g), while six crosses L1xT2, L1xT4, L3xT2, L4xT4, L5xT4 and L6xT1 exhibited highest positive significant heterosis for yield per plant (kg) in both HB and RH ranged from 16.09% to 88.46% respectively. Heterotic hybrids with maximum number of studied desirable yield contributing traits (8) of both RH and HB were identified only two crosses L1xT2 and L4xT4.
