20.500.12556/RUL-175636 Inheritance mechanism of fruit yield and yield-related traits in tomato for cadmium stress tolerance Mehanizmi dedovanja tolerance na kadmijev stres pri pridelku plodov in z njim poveznih lastnosti pri paradižniku Understanding inheritance patterns and yield-related traits under cadmium stress is essential for breeding strategies that reduce cadmium’s negative effects on crops. In a study, fifteen F1 tomato hybrids from six genotypes were evaluated under both cadmium and non-cadmium conditions. The genetic analysis confirmed that a simple additive-dominance model explained the inheritance of most traits, suggesting that a few genes, often with one having a stronger effect, control these traits. Over-dominance was observed in most traits, and genotypes P3 and P5 carried the most dominant genes, performing best under cadmium stress. Heritability estimates showed that, under non-cadmium conditions, traits like branch number, fruit set, fruit mass, and locule number had medium narrow sense heritability, indicating dominance gene action was the main factor in inheritance. Other traits with low heritability also pointed to the importance of dominance effects. As a result, P3 and P5 genotypes were more tolerant to cadmium stress due to their dominant gene composition. Understanding the roles of dominance and non-additive gene action can guide the development of high-yield, cadmium-tolerant tomato varieties. average degree of dominance Cd stressed gene action heritability Solanum lycopersicum variance/covariance graphs poprečna stopnja dominance Cd stres delovanje gena dednost Solanum lycopersicum statistična analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2025-11-06 15:23:16 2025-11-06 15:23:22 2025-12-13 03:55:18 0000-00-00 00:00:00 2025 0 0 11 str. no. 3 Vol. 121 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2025.121.3.22246 256229635 ABDELSATAR+et+al.+(G).pdf ABDELSATAR+et+al.+(G).pdf 1 0F59E2DC9E9CA5AF1C3A71D69968936F de66ea6b4bc9e4528c847b0fa01599e4be6bd2174f4d38b404b65b0465a19967 202b26f0-bb1c-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221480 https://journals.uni-lj.si/aas/article/view/22246/18913 1 d4a9af4b-bb1b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=221479 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
