Genotypes differing in height were found to differ in biomass partitioning among organs and a tall hybrid had significantly increased radiation use efficiency: a novel finding in sorghum. Experiments on diverse genotypes of sorghum that underpin the development and testing of the adapted crop model are detailed.
#APSIM SOURCE CODE SOFTWARE#
The model builds on existing approaches within the APSIM software platform. The approach quantifies capture and use of radiation, water, and nitrogen within a framework that predicts the realized growth of major organs based on their potential and whether the supply of carbohydrate and nitrogen can satisfy that potential. It is designed to exhibit reliable predictive skill at the crop level while also introducing sufficient physiological rigour for complex phenotypic responses to become emergent properties of the model dynamics. A generic cereal crop growth and development model is outlined here. Suitably constructed crop growth and development models have the potential to bridge this predictability gap. #' The \sQuote if ( upp.Progress in molecular plant breeding is limited by the ability to predict plant phenotype based on its genotype, especially for complex adaptive traits.
