Two teosintes made modern maize
Science, 2023The origins of maize were the topic of vigorous debate for nearly a century, but neither the current genetic model nor earlier archaeological models account for the totality of available data, and recent work has highlighted the potential contribution of a wild relative, Zea mays ssp.

Teosinte crossing barrier1, a locus governing hybridization of teosinte with maize
Theoretical and Applied Genetics, 2001A teosinte gene or gene cluster, Teosinte crossing barrier1 (Tcb1), that restricts crossability with maize mapped 6 centiMorgans distal to sugary-1 on chromosome 4. Tcb1 is loosely linked with the gametophyte-1 locus whose Ga1-s allele, present in many popcorns, confers nonreceptivity to the pollen of other maize varieties (ga1).

Teosinte Cytoplasmic Genomes: II. Performance of Maize Hybrids with Teosinte Cytoplasms
Crop Science, 1996Alien cytoplasm substitution effects on quantitative agronomic characters in maize breeding germplasm have been studied many times, but few cytoplasmic effects have been found. This research was conducted to evaluate the importance of nuclear sources of variation often confounded with cytoplasmic effects, and to study effects of substituting teosinte ...

Teosinte Cytoplasmic Genomes: I. Performance of Maize Inbreds with Teosinte Cytoplasms
Crop Science, 1996Cytoplasmic variation in maize (Zea mays L.) is known to influence qualitative phenotypes such as male sterility and teosinte‐cytoplasm‐associated miniature. Cytoplasmic influences on quantitative characters such as grain yield have been difficult to document.

Phyllochron estimate for the teosinte crop
Sigmae, 2023O objetivo deste trabalho foi estimar o filocrono para a cultura de teosinto em datas de semeadura. Foi conduzido um experimento em 12 datas de semeadura (08/10/2021 a 01/01/2022). As semeaduras foram realizadas em uma fileira de 5 m de comprimento, espaçadas em 0,80 m entre fileiras e 0,20 m entre plantas na fileira. Em cada data de semeadura marcaram-

Maize × Teosinte Hybridization
1994The greatest part of the genetic variability of maize has been caused or maintained by the introgression of wild germplasm, especially of the taxa closest to the cultivated species: the teosintes. There exists good documentation regarding the existence of F1 Hybrids and advanced generations, derived from the same, produced by natural Hybridizations ...

Seed Dormancy in Mexican Teosinte
Crop Science, 2011Seed dormancy in wild Zea species may affect fitness and relate to ecological adaptation. The primary objective of this study was to characterize the variation in seed germination of the wild species of the genus Zea that currently grow in México and to relate this variation to their ecological zones of adaptation.
