The Genomic Signature of Crop-Wild Introgression in Maize [PDF]
PLoS Genetics 2013 9(5): e1003477, 2012 The evolutionary significance of hybridization and subsequent introgression has long been appreciated, but evaluation of the genome-wide effects of these phenomena has only recently become possible. Crop-wild study systems represent ideal opportunities to examine evolution through hybridization.

Combining randomized field experiments with observational satellite data to assess the benefits of crop rotations on yields [PDF]
Environmental Research Letters (2022). Volume 17, Number 4, 2021 With climate change threatening agricultural productivity and global food demand increasing, it is important to better understand which farm management practices will maximize crop yields in various climatic conditions. To assess the effectiveness of agricultural practices, researchers often turn to randomized field experiments, which are reliable for ...

Antioxidative enzyme activities in maize genotypes grown under saline water irrigation
Electronic Journal of Plant Breeding, 2017 Plants with high levels of antioxidant enzymes have been reported to have greater tolerance to this oxidative damage caused by salinity. Role of antioxidative enzyme activity in salt stress and screening maize hybrids for salinity tolerance was ...

Genetic characterization of early maturing maize hybrids (Zea mays L.) obtained by protein and RAPD markers [PDF]
, 2005 Knowledge of maize germplasm genetic diversity is important for planning breeding programmes, germplasm conservation per se etc. Genetic variability of maize hybrids grown in the fields is also very important because genetic uniformity implies risks of ...

A Hybrid Two-layer Feature Selection Method Using GeneticAlgorithm and Elastic Net [PDF]
, 2020 Feature selection, as a critical pre-processing step for machine learning, aims at determining representative predictors from a high-dimensional feature space dataset to improve the prediction accuracy. However, the increase in feature space dimensionality, comparing to the number of observations, poses a severe challenge to many existing feature ...

Drought responses of foliar metabolites in three maize hybrids differing in water stress tolerance. [PDF]
PLoS ONE, 2013 Maize (Zea mays L.) hybrids varying in drought tolerance were treated with water stress in controlled environments. Experiments were performed during vegetative growth and water was withheld for 19 days beginning 17 days after sowing.
