Improving tomatoes keeping quality is crucial for reducing post-harvest losses. Knowledge on heterosis, and combining ability is pre requisite for breeding high yielding and good shelf life heterotic hybrids. An investigation was undertaken with each of 3 lines, testers, and 9 hybrids to identify desirable parents and crosses for 20 fruit biochemical, morpho-physiological, and yield traits and to elucidate nature of gene action for shelf life and its contributing traits through Line × Tester analysis. The lines contributed to most of hybrids variability than testers and fruit quality traits had higher degree of SCA variance as compared to GCA variance. pH, ascorbic acid, fruit firmness, and plant height governed by additive gene action. Lycopene, titratable acidity, TSS, calcium, magnesium, pericarp thickness, pulp content, locule number, fruit length, diameter, weight, shelf life, number of branches, number of clusters, number of fruit/cluster, and yield/plant were under the control of non-additive gene action. All the lines and Arka Saurabh were best general combiners and IIHR 2349 × Arka Vikas, IIHR 2349 × Arka Saurabh, IIHR 2358 × Arka Ahuti and IIHR 2357 × Arka Ahuti were the best specific combiner in producing heterotic hybrids. IIHR 2349 × Arka Vikas and IIHR 2349 × Arka Saurabh were promising hybrids for high yield and shelf life. The crosses involved both parents with high, one parent with high and other with low and both parents with low good overall general combining ability status respectively indicated the additive, non-additive and epistatic gene action in fruit quality and yield traits inheritance.

“…The tomato genotypes or lines were screened using the 140 SNPs with a minimum of 10 SNPs for each tomato chromosome. One hundred and forty (140) SolCap SNPs were converted to allele-specific primers by Ag-Biotech, Inc. Information from Yogendra and Ramanjini (2013) and Vrebalov et al (2002) was used to design KASP primer sets by Ag-Biotech, Inc. A total of 19 SNPs that were unlinked to the target gene were used for background selection.…”

Tomato is one of the most important vegetable crops cultivated and consumed worldwide. Demand is increasing daily because of increase in per capita fresh fruit consumption. Despite the economic importance of tomato, it has relatively short shelf-life after ripening and experiences remarkable post-harvest losses. This study was aimed at using marker-assisted backcrossing (MABC) to transfer shelf-life gene (alc) into the genetic background of two elite Ghanaian tomato breeding lines. The MABC derived lines at BC2F3 were evaluated to confirm selections using molecular markers. All the MABC-derived lines gave significant extended shelf life compared to the checks except for Alc-LA3134, the alc donor parent, which was, however, not significantly different from one of the backcrosses (BC2F2.3-E-80-19-26). This confirms that the genetic regulation of the shelf-life trait is dependent on the alc gene. The performance of the donor check (Alc-LA3134) against the 12 MABC-derived lines indicated no significant differences for the fruit firmness (except for BC2F2.3-E-80-19-4), number of locules per fruit and shelf life (for only BC2F2.3-E-80-19-26), thus suggesting similar backgrounds of the MABC as the recurrent parents. A considerable increase in the shelf-life value was observed among the MABC-derived lines. The introgression of the alc gene into cultivated tomatoes for extended shelf-life could reduce post-harvest losses of tomato in Ghana.

“…The pre-harvest treatments of fruits with vinegar, salicylic acid (Chavan and Sakhale 2020), origanum oil, calcium chloride, and anti-sense RNA technology are e cient methods in extending the shelf life of tomatoes but these technologies are laborious, unfeasible in farmer's eld and need social acceptance. Therefore, Identi cation of tomato germplasm lines with high shelf life and other associated fruit quality traits is the best option and safest way (Yogendra and Gowda 2013).…”

Prolonging the keeping quality of tomatoes is very essential for reduction of great losses in quality and quantity. Fruit shelf life is ripening-associated complex trait affected by many quantitative fruit quality traits. In this study, 30 tomato germplasm lines were characterized for very important less pursued shelf life and its contributing traits. Shelf life ranged from 10.50 to 34.43 days. Slower dehydration rate noticed in tender fruit tissues in turning stage. Slow pace in rate of change in physiological losses in fruit weight led to high shelf life. Fruit firmness ranged from 2.49 to 5.76 kg/cm2 and pericarp thickness from 1.33 to 6.70 mm. High shelf life germplasm lines contained 6.98–19.29 mg/100g and 8.64–13.38 mg/100g of fruit calcium and magnesium content respectively. The fruit epicuticular wax content varied from 34.64 to 96.77 µg/cm2. Calcium, magnesium, and epicuticular wax decrease respiration rate, maintain firmness, delay senescence, reduces incidence of physiological disorders and extend fruit storage life. Higher shelf life in germplasm lines P-4, L-00191, L-03686, AR-23, PKM-1, and Bony best are contributed by higher firmness and epicuticular wax content and high shelf life in Red ball is due to higher firmness, pericarp thickness, calcium, magnesium and epicuticular wax content.
