“…These mutants can be used as elders in plant breeding programs to produce new superior tomato cultivars with longer fruit shelf life (Mubarok et al, 2015;Wiguna et al, 2021). With the production of this shelf-resistant commercial tomato cultivar, the post-harvest problem in tomato fruits can be solved.…”

The presence of ethylene during postharvest handling of tomatoes can be the main problem in maintaining fruit shelf-life by accelerating the ripening process and causing several quality changes in fruit. Several researchers have studied the methods for improving the postharvest life of tomato fruit by controlling ethylene response, such as by mutation. New ethylene receptor mutants have been identified, namely Sletr1-1, Sletr1-2, Nr (Never ripe), Sletr4-1, and Sletr5-1. This review identifies the favorable and undesirable effects of several ethylene receptor mutants. Also, the impact of those mutations on the metabolite alteration of tomatoes and the future perspectives of those ethylene receptor mutants. The review data is taken from the primary data of our experiment related to ethylene receptor mutants and the secondary data from numerous publications in Google Scholar and other sources pertaining to ethylene physiology. This review concluded that mutation in the SlETR1 gene was more effective than mutation in NR, SLETR4, and SLETR5 genes in generating a new ethylene mutant. Sletr1-2 mutant is a potential ethylene receptor mutant for developing new tomato cultivars with prolonged fruit-shelf life without any undesirable effect. Therefore, that has many challenges to using the Sletr1-2 mutant for future purposes in breeding programs.

The demand for tomato fruit has increased along with the human population. The increasing income of peoples also affect the demand orientation for high nutrition content and the shortage of resources is the obstacle for future tomato farming. Breeding tomato has been intended to create a new cultivar with high yield and quality. Previously, there were fourteen selected promising lines with high fruit firmness and yield components resulting from plant breeding program. Therefore, further steps need to be evaluated regarding yield potential and the plant quality. This study aimed to identify fourteen promising lines of high yield and high quality and compared to commercial varieties. Fourteen tomato accessions were evaluated by three control varieties. The accessions and controls varieties were assigned in a randomized completely block design (RCBD) with three replications. Data collections were analyzed using Analysis of variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) analysis with α = 5%. Path analysis showed that the selection criteria for selecting high yield of tomato lines were fruit length, pulp thickness, fruit weight /plant, and flowers number per bunch. There were five lines of fourteen accessions which had high yield potential and four tomato lines which had worth considering fruit size and fruit firmness. These lines contained high potential characters to be used as breeding materials for improvement of hybrid.

“…An approach to this issue is developing tomato cultivars with an extended shelf life. Previous research has shown that genetic mutations that affect specific genes can alter fruit ripening, senescence, and shelf life [4] [5]. Hybridization is a promising strategy for developing new tomato varieties with desirable traits, as it involves crossing two genetically different individuals.…”

Enhancing fruit quality and yield is the goal of creating superior tomato varieties. One area of concern for breeders is fruit shelf life. To produce better offspring, hybridization attempts to combine the traits of two parents, but the results can be unpredictable. Backcrossing can create stable offspring with desired traits and eliminate undesirable characteristics from the parent plants. This study aimed to assess the diversity among advanced backcross strains and to obtain backcross genotypes carrying mutant alleles that have a high level of similarity with the superior parental lines. The study was carried out from April to September 2019 at the Indonesian Vegetable Research Institute’s screen house. In this experiment, two populations of backcrossing comprised of commercial parents of ‘Intan’ and ‘Mutiara’ varieties as well as backcross genotypes including MBC3F1 32, MBC3F1 32.2, MBC3F1 32.3, MBC3F1 37.2, MBC3F1 45.3, MBC3F1 37.1, IBC3F1 34.2, IBC3F1 37.2, and IBC3F1 34 were utilized. A variance analysis was used to determine genotype diversity. The genetic similarity between parents and offspring was determined using cluster analysis, and a t-test was used to compare mean performance values. According to the results, the BC3F1 populations of ‘Intan’, and ‘Mutiara’ exhibited a high degree of phenotypic variability. Cluster analysis and a t-test revealed that the IBC3F1.37.2 and IBC3F1.45.3 genotypes resembled ‘Intan’, furthermore MBC3F1.34 and MBC3F1.34.2 had strikingly similar characteristics to ‘Mutiara’. Therefore, several individual plants carrying the Sletr1-2 mutant allele in these four genotypes can further assemble longer tomato fruit shelf life and high-yielding varieties.
