Eloquent information about the genetic basis of inheritance is important for any breeding program. Therefore, a diallel study was conducted under the influence of tomato leaf curl virus (TLCV) disease, using the eleven advanced lines of tomato. Firstly, information regarding percent disease index (PDI) was determined via artificial screening with viruliferous whiteflies. Later, these lines were crossed in a half diallel mating design to produce fifty-five one-way hybrids. These hybrids and parental genotypes were evaluated for morphological and biochemical traits under open field conditions. Using the Griffing approach (Method II and Model I), the basis of the inheritance of traits was determined. Furthermore, a Bayesian model was applied to the total yield descriptor. Correlation data indicated that total yield was not correlated with any other trait. The significant general combining ability (GCA) and specific combining ability (SCA) values indicate exploitable genetic variation. The broad-sense heritability values were larger than narrow-sense heritability, showing that selection will be efficient for the improvement of these traits. Hybrid combinations H23, H42 and H49 can be considered efficient for the selection of multiple traits, including yield. Overall, this study provides useful information regarding the genetics of important traits of tomato under TLCV infestation.

“…The fruit length and diameter in tomato hybrids is also associated with their genetic makeup, and governed by the cell size and intercellular space of the flesh (Khapte et al 2018). The results are in confirmation with finding of (Shende et al 2012 andPandiarana et al 2015) for fruit length and (Solieman et al 2013) for fruit weight in tomato hybrids. For fruit diameter the hybrid P 3 × P 1 and P 2 × P 7 were heterotic over check hybrid NUN 5024 and no hybrids were heterotic over check hybrid COTH-3 for fruit diameter.…”

“…Even though a large number of hybrids have been released so far, most of them are of round in shape, however some of the oblong/square blocky fruited hybrids are released by the private sector but their seeds are costly. The hybrids available in the market do not have good processing qualities, leading to limited development of value added products (Pandiarana et al 2015). Oblong fruited hybrids can be used for fresh market as well as for processing because of their high TSS and dry matter content.…”

Heterosis in oblong fruited tomato (Solanum lycopersicum) hybrids for growth and yield traits

2019

In the present investigation, oblong fruited nine tomato lines were crossed in full diallel mating design to produce 72 F1 hybrids. Heterobeltiosis and standard heterosis were estimated for growth, fruit yield and quality traits in F1 hybrids. The parental lines, viz. BRML (P3), Arka Ashish (P4), Vybhav (P5), IIVR-L (P6), EC 608406 (P7) and EC 608395 (P8) were found most promising for exploiting heterosis. Considering all the cross combinations individually, the hybrid combinations that out fielded their parents for a maximum number of components for heterobeltiosis and standard heterosis coupled with highper se values were; IIVR-LÃ—Arka Ashish (P6Ã— P4), IIVR-LÃ—Vybhav (P6Ã— P5), EC 608406 Ã— BRML (P7Ã— P3), EC 608395 Ã—IIVR-L (P8Ã— P6) and EC 608406 Ã—IIVR-L (P7Ã— P6). However, hybrids those performed better for yield parameters were not heterotic significantly for quality parameters except P7Ã— P3. The standard heterosis noted in outperforming hybrids P7Ã— P3 (23.99% and 19.80%) and P6Ã— P4 (18.97% and 14.95%) over check hybrids NUN 5024 and COTH-3 respectively. The yield per plant based on per se values were also highest in hybrids P7Ã— P3 (3.91 kg) and P6Ã— P4 (3.75 kg). These promising hybrids could beused for dual purpose (fresh market as well as processing), since they have improved economic traits besides good fruit quality parameters (high TSS) and oblong in shape.

“…Therefore, hybrids FDT 4 × UC-OP, FDT 2 × Ib-local and UC-OP × Ib-local which involves one parent with a high GCA effect for number of fruits per plant and fruit mass per plant may be considered useful for the improvement of fruit yield, lycopene, vitamin C and total soluble solid and heterosis breeding may be recommended (Saleem et al, 2013a). These hybrids would be expected to produce segregants of a fixable nature in segregating generations through the simple pedigree method (Pandiarana et al, 2015).…”

Tomato (Solanum lycopersicum L.) is one of the most important vegetable crops grown in Nigeria, either for fresh market or industrial purposes, necessitating the development of a robust tomato breeding programme aimed at maximizing genetic improvement on economically important traits. In this study, the combining ability, nature of gene action, heterosis, and heritability for morphological, nutritional, and physicochemical parameters of tomato were examined in five tomato parents and ten F1 offsprings, generated with a 5 × 5 half diallel mating design in the greenhouse in 2017. The field evaluation was conducted at the Teaching and Research Farm of Ladoke Akintola University of Technology, Ogbomoso, Nigeria during the cropping season of 2018 using a randomized complete block design with three replications. Analysis of variance for combing ability revealed that both additive and nonadditive gene actions contributed to the fundamental genetic mechanism underlying the inheritance of the measured traits. The top two general combiner parents were UC-OP and Ib-local. Furthermore, the best tomato hybrid specific combiners were FDT4 × UC-OP, FDT2 × Ib-local and UC-OP × Ib-local which involved one parent having a high general combining ability effect for fruit yield and the other having other desirable traits. These hybrids may be further utilized in tomato breeding programmes.
