“…x EC-521067 (-7.12) to EC-631364 x Arka Meghali (-6.37). Negative heterosis for earliness days to first flowering was more overobserved by Asati et al (2007), Singh et al (2008), Kumari and Sharma (2011) and Shankar et al (2014) indicated that heterosis over superior, mid and standard parent were the negative course which back our finding.…”

“…Average fruit weight specifically influences the full abdicate, so this character is exceptionally imperative so distance adds up to surrender is concerned. Shankar et al (2014) and Kumari and Sharma (2011) moreover detailed positive heterosis up to 10 to 40 percent for average fruit weight in tomatoes. High Average fruit weight is of prime significance in breeding high-yielding cultivars.…”

“…Investigating common differences as a source of novel alleles to move forward the efficiency, quality and nutritional esteem of the edit is the baseline of any breeding program. Effective misuse of heterosis in tomatoes is temperate since each natural product contains more seeds than other vegetables (Kumari and Sharma, 2011). Presently a day, agriculturists are exceptionally much slanted to develop hybrid assortment for having tall yielding and to induce great quality natural products.…”

Ten parental lines of tomato (Lycopersicon esculantum Mill.) were crossed in 10 x 10 diallel mating plan barring reciprocals. The 45 F1 hybrids along with their parents and one standard check (Pusa Ruby) were evaluated in a randomized block design with three replications. This study relevant that heterosis over the better parent, mid-parent, standard check and inbreeding depression was observed for all the traits under study. Highly significant heterosis was observed for Days to first flowering (-18.35, -14.42 and -3.30%), Days to 50% fruiting (-13.41, -12.30 and -6.71%), Fruit diameter (41.20, 46.07 and 35.57%), fruits length (49.20, 63.23 and 5.98%), Average fruit weight (59.26, 66.89 and 26.72%), Number of fruits per plant (135.19, 159.63 and 80.67%), Number of fruits per cluster (54.55, 54.55 and 80.02%) and total yield per plant (123.71, 146.41 and 99.13%) over the better, mid and standard parents, respectively along with considerable inbreeding depression. The most promising cross EC-165700 × EC-164563 appeared intensely noteworthy positive heterosis over way better parent for total yield per plant. These Heterotic hybrids found superior over better parents and one standard check have the potential to be exploited commercially.

“…Significant negative heterosis for this character has been reported by Rana and Vidyasagar (2005), Rattan (2007), .The range of heterosis over better parent for fruit yield per plant (Kg) recorded from -70.26 per cent (JTL-16-08 × DVRT-2) to 206.04 per cent (JTL-15-02 × Punjab Chhuhara). The range of standard heterosis for this trait varied from -66.32 per cent (JTL-16-08 × AT-3) to 189.32 per cent (JTL-15-05 × DVRT-2).Similar findings were reported by Panchal et al, (2017), Sureshkumara et al, (2017), Tamata and Singh (2017), Triveni et al, (2017), Kattegoudar et al, (2018), Sundharaiya et al, (2018).…”

rabi season of 2017-19 to study performance of nine lines and four testers into thirty-six tomato hybrids for fruit yield and its component traits by Line x Tester analysis. The analysis of variance for seventeen characters showed significant differences for all the genotypes indicating that experimental material had sufficient genetic variability for all the characters studied. Among 36 hybrids, 9 and 12 hybrids manifested significant desirable heterobeltiosis and standard heterosis for fruit yield per plant. The heterobeltiosis for fruit yield ranged from -70.26 to 206.04 % while standard heterosis ranged from -66.32 to 189.32 %. The cross JTL-15-02 × Punjab Chhuhara exhibited the highest desirable heterosis over better parent followed by JTL-15-05 × DVRT-2. These hybrids exhibited desirable heterosis for important yield attributes suggesting that the heterosis for marketable yield was associated with heterosis for component characters.

“…Highly productive competitive domestic hybrids and varieties are needed, the development of which is based on the use of a new type of donors obtained from lines with functional male sterility (FMS) and a complex of economically valuable traits. Heterozygous hybrids usually outperform their homozygous parents in yield; quantity, size and quality of fruits; show increased metabolic activity and usually better resistance to insect pests, diseases and extreme temperatures and, ultimately, have better economically valuable characteristics [3]. Currently, the main method for developing heterotic hybrids is combination breeding, which is based on hybridization.…”

In world agriculture, the tomato plays a leading role due to its high nutritional properties, high yields, adaptive abilities and a wide range of uses in fresh, culinary and processing industries. The global tomato market volume is more than 160 million tons. In the ranking of countries, Russia is in 6th place in terms of area and 11th in terms of gross production of tomatoes. Unfortunately, at the moment, a significant part of tomato seed material is imported. The implementation of the import substitution program creates the need to develop domestic breeding and seed production of this crop. The purpose of these studies was to conduct a breeding assessment of parental tomato lines for productivity traits based on statistical analysis methods and to identify promising source material for further breeding work to develop highly productive hybrids. As a result of the research, three best combinations were identified in terms of productivity of hybrids: 2f2-16(8-2) x Veneta, 108t/20 x Victor and 2f216(8-2) x Victor, which have a positive effect of specific combining ability, have average and high positive effects of the general combining ability of both maternal and paternal lines. Two maternal lines 108t/20 and 3f-14 showed a positive general combining ability for early and total productivity and its components. therefore, these parents can be successfully used in future breeding programs.
