This variation, arising from the lack of ...

Diverse collections of barley germplasm are being assembled and mined via genome-wide association studies and the identified variation can be linked to the barley sequence assembly.

متن کاملThe Virtual Crop-modelling System ‘vica’ Specified for Barley
The paper presents an improved version of the Virtual Canopy model VICA (Wernecke et al. 2000), which is developed to establish a generic functional-structural plant model (FSPM; cf. Vos et al. this volume) specified for barley (Hordeum vulgare L.). The model core is formulated as a set of hierarchically structured objects. These objects are related to morphological and functional ‘plant units’...
