Abstract we have used polymorphic chloroplast simple sequence repeats (cpssrs) to analyse levels of diversity and relationships within the genuszea between two and nine alleles were found at 15 polymorphic loci and combining the data from these loci gave 32 haplotypes in the 37 accessions studied.

The effect of low temperature on the physiology of maize has been well studied, but the genetics behind cold tolerance is poorly understood to better understand the genetics of cold tolerance we conducted a quantitative trait locus (qtl) analysis on a segregating population from the cross of a cold. As z mays ssp parviglumis, shares a particularly close genetic relationship with maize and available evidence indicates that it is the direct ancestor of maize (15, 54.

Abstract this study demonstrates the relative ease of generating high-density linkage maps using the aflp® technology two high-density aflp linkage maps of zea mays l were generated based on: (1) a b73 × mo17 recombinant inbred population and (2) a d32 × d145 immortalized f 2 population.
Previously, we detected significant associations between polymorphisms in nine candidate genes and phenotypic variation in the maize ancestor, balsas teosinte (zea mays ssp parviglumis) (w eber et al 2007) our study builds upon our prior analyses in several ways, including an increase in the numbers of individuals, candidate genes, and traits.
