ZmCCA1a on Chromosome 10 of Maize Delays Flowering of Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2020
Maize (Zea mays) is a major cereal crop that originated at low latitudes, and thus photoperiod sensitivity is an important barrier to the use of tropical/subtropical germplasm in temperate regions.

Integrating Wheat Canopy Temperatures in Crop System Models

open access: yesAgronomy, 2016
Crop system models are generally parametrized with daily air temperatures recorded at 1.5 or 2 m height. These data are not able to represent temperatures at the canopy level, which control crop growth, and the impact of heat stress on crop yield, which ...

Evolutionary plant breeding for low input systems [PDF]

open access: yes, 2005
Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to
