Abstract
From an economic standpoint, tomatoes are considered the second most valuable agricultural product after potatoes. In terms of per capita consumption worldwide, tomatoes closely follow potatoes. However, tomato production in Iran faces challenges, particularly low yield per unit area. One contributing factor is the limited use of high-quality hybrid seeds. The objective of the present study is to predict the phenotypic characteristics of commercial Amaris hybrid parents. In this research, the Amaris variety (a type of cherry tomato) was cultivated in a greenhouse in Shahrekord in 2021. Approximately 100 self-pollinated seeds were collected from ripe fruits of this cultivar and replanted alongside Amaris hybrid seeds. The desired traits of these plants were recorded. Based on similarities with parental plants, specific genotypes were selected. For the first component, genotypes 1, 21, 25, 39, 44, 47, 58, 59, 66, 31, 32, 34, and 35 were chosen. For the second component, genotypes 3, 6, 8, 23, 46, 52, 56, 76, and 37 were identified. It is anticipated that Amaris hybrids will be obtained by crossing individual plants from these selected groups after further purification. Among the candidate individuals, genotypes 11 and 47 exhibit the closest resemblance to one parent, while genotypes 21 and 25 are similar to another parent. By carefully selecting and purifying the progeny based on this genetic combination, commercial hybrids similar to Amaris can be produced.
