Selection and Breeding for High β-Carotene Content (Provitamin A) in Tomato

Genetic Improvement of Tomato

“…Fruit pigmentation after hybridization of the cultivated tomato with green-fruited species has been the object of many investigations (Lincoln et al 1943;Lesley 1943, 1947;Porter and Szheile 1946;Kohler et al 1947;Chmielewskii andBerger 1962, 1966;Chmielewski 1968;Rick 1974;Manuelyan et al 1975;Slavov 1975;Georgieva 1976;Ayuse et al 1986). Fruit pigmentation after hybridization of the cultivated tomato with green-fruited species has been the object of many investigations (Lincoln et al 1943;Lesley 1943, 1947;Porter and Szheile 1946;Kohler et al 1947;Chmielewskii andBerger 1962, 1966;Chmielewski 1968;Rick 1974;Manuelyan et al 1975;Slavov 1975;Georgieva 1976;Ayuse et al 1986).…”

“…The first publications communicating about the development of f3-carotene lines by hybridization with L. hirsutum f. typicum are from Lincoln et al (1943), Kohler et al (1947) and Lincoln and Porter (1950). On the basis of crosses with the same wild species the first f3-carotene cultivar Caro red (Tomes and Quackenbush 1968) and later the cultivar Caro rich, having fruits with higher f3-carotene content (Tigchelaar and Tomes 1974) were developed.…”

Comparison of the Carotene and Nitrogen Contents of Alfalfa Forage from Selected Clonal Lines1

“…On the average 77% of the carotene content of the plant was found in the leaves. Varietal or genetic differences shown to affect the carotene content of other plants have been pointed out by Kohler et al ( 5) for tomato fruits, and by Aurand,Miller and Huber ( 1) for the grain of yellow dent corn.…”

Análisis de la variabilidad en poblaciones naturales de Solanum, secciones Lycopersicon y Basarthrum.

“…Recientemente, se ha publicado una revisión de este tema, distinguiendo entre la mejora de la calidad en tomate para industria (Gragera 2006) y para consumo en fresco (Roselló y Nuez 2006 habrochaites (Lincoln et al 1943;Kohler et al 1947). Asimismo, también se han descrito numerosos QTLs introgresados de S. pimpinellifolium, S. habrochaites, S. pennellii, S. peruvianum y S. neorickii, que influyen sobre el color del fruto (Labate et al 2007).…”
