“…It is worthwhile also at this point to call attention to the wild tomato used in breeding experiments by Holmes (1939) and Lesley and Lesley (1943). This material, which was all derived from a single viable seed obtained from a herbarium specimen (No.…”

“…This fine dissection in addition to the presence of 11 large segments are features scarcely ever seen in leaves of 1. peruuianum. Lesley and Lesley (1943), moreover, mention the difficulty they experienced in growing this collection and also call attention to the brittleness of its shoots. Their illustration, furthermore, shows the characteristically long peduncles.…”

“…Mull.) and species of Eriopersicon, in addition to the difficulty of their production, have been found to be rather sterile in spite of the fact that the behavior of meiotic chromosomes was normal in the first hybrids studied (Lesley and Lesley, 1943). MacArthur and Chiasson subsequently (1947) attributed the sterility of the F 1 of L. esculentum Mill.…”

Taken partly from a thesis submitted by the senior author to the Graduate Division of the University of California in partial fulfillment of the requirements for the degree of Doctor of Philosophy. The junior author provided supplementary data on compatibilities of the species hybrids and observations on the pollination relations of the species in Peru during tenure of a fellowship of the John Simon Guggenheim Memorial Foundation.

Identification and assessment of alleles in the promoter of the Cyc‐B gene that modulate levels of β‐carotene in ripe tomato fruit

Novel diversity may be mined from databases and de novo sequencing, but functional characterization remains a limiting step to identifying new alleles. Classical breeding approaches augmented by marker‐assisted selection offer a means to rapidly assess the function of new variation in coding or regulatory regions to modulate traits. We used the Cyc‐B gene (B) of tomato (Solanum lycopersicum L.) for a proof of concept because of its role in the production of β‐carotene, a provitamin A carotenoid with importance to human nutrition. We measured carotenoid content in vintage and contemporary varieties and the profiles had a range of β‐carotene from 0.2 to 4.06 mg 100 g−1 fresh weight. We characterized variation in B from 84 sequences recovered from public databases and from an additional 29 high β‐carotene tomato, S. galapagense S. C. Darwin & Peralta, and S. cheesmaniae (L. Riley) Fosberg accessions. Thirteen unique haplotypes across 1600 bp of sequence 5′ to the first ATG were identified with 11 occurring in high β‐carotene accessions we sequenced, and additional haplotypes were identified in public data. Phylogenetic analysis suggested that the alleles in high β‐carotene varieties were derived from wild species. Association analysis suggested two single nucleotide polymorphisms (SNPs) as the most likely causes of high β‐carotene, presumably through their influence on transcription of B that is elevated in ripening fruit. A marker‐assisted backcross breeding scheme leveraging SNPs for background genome selection was used to rapidly develop germplasm resources containing different alleles of B in a uniform genetic background. Evaluation demonstrated that distinct promoter haplotypes function as different alleles that can be used to modulate the levels of β‐carotene in tomato.
