Abstract
Meiosis and recombination lead to gametes with novel combinations of genes as key processes in evolution and plant breeding. Numerous extrinsic factors have been reported to affect meiotic recombination of plants. The goal of this research was to identify simple, low-cost and effective treatments that affect recombination in maize (Zea mays L.). The treatments, water-deficit stress and defoliation, were separately applied to two F1-generation genotypes, B73/Mo17 and Mo17/H99. The F1 plants were backcrossed to an inbred line to produce the backcross populations that were genotyped at microsatellite loci on chromosomes 1 and 10. Overall, 1,271 crossovers were observed in the progeny of the water-stressed plants while 1,092 were observed in the progeny of the non-stressed plants. The water-deficit treatment may have increased the rates of recombination in both F1-genotypes while the defoliation treatment was ineffective.

Description of the data and file structure
The file contains all raw data and information necessary to support the research findings. The file contains all segregation data collected from all populations described in the manuscript. The file format lists the individual number (1-93) per chromosome of each population along the top, horizontally. On the left side of each of the tables, the first column contains names of the micro satellite loci. The segregation data is represented with letters 'H' or 'B'. Each tab's name describes the Chromosome number, population, stress, and germplasm name, e.g. (Chr1 pop1 WS b73mo17 - chromosome1, population 1, Water Stress, germplasm is B73/Mo17)

Description: The file contains data and distribution of crossovers on chromosome 1 and 10 of 3 maize populations. The populations were exposed to water-deficit and defoliation stress with a control population also included. Regions with crossovers are highlighted in yellow.
