Molecular breeding of a novel orange-brown tomato fruit with enhanced beta-carotene and chlorophyll accumulation
BACKGROUND Tomatoes provide a significant dietary source of the carotenoids, lycopene and β-carotene. During ripening, carotenoid accumulation determines the fruit colors while chlorophyll degradation. These traits have been, and continue to be, a significant focus for plant breeding efforts. Previous work has found strong evidence for a relationship between CYC-B gene expression and the orange...
متن کاملInheritance of Beta Carotene Content in the Wild Tomato Species Lycoporsicon cheesmanii
Beta carotene and lycopene, the two principal colored carotenoids present in tomato fruit, were measured in mature fruit of parental, F,, F2, and backcross populations derived from an initial cross of an orange-fruited accession of the wild tomato species Lycopersicon cheesmann Riley with the cultivated tomato L esculentum Mill. Segregation patterns for fruit pigmentation and percentage beta ca...
متن کاملOptimizing sampling of tomato fruit for carotenoid content with application to assessing the impact of ripening disorders.
Color defines one aspect of quality for tomato and tomato products. Carotenoid pigments are responsible for the red and orange colors of tomato fruit, and thus color is also of dietary interest. The aims of this study were (1) to determine the relative importance of field sampling and analytical replication when measuring lycopene and beta-carotene in tomato fruit and (2) to determine the effec...
متن کاملModification and Dominance of the Gene Governing Formation of High Concentrations of BETA-Carotene in the Tomato.
ROM the progeny of crosses between normal canning tomatoes, LycoperF sicon esculentum Mill., and the wild species L. hirsutum Humb. and Bonpl., LINCOLN et al. (1943) and KOHLER et al. (1947) isolated a new tomato type which was distinguished from normal tomatoes by producing orange fruits in which most of the carotene produced was beta-carotene. From the study of a cross between the red canning...
متن کاملGenetic and Environmental Variation for Tomato Flesh Color in a Population of Modern Breeding Lines
The genetic and environmental variation for flesh color of tomato (Lycopersicon esculentum Mill.) fruit was quantified using 41 red-fruited breeding lines, open-pollinated cultivars, and hybrids that are representative of the diversity of tomatoes grown for whole-peel processing in the midwestern and eastern United States and Ontario, Canada. Objective color measurements were made for 2 years f...
