Integrating molecular and physiological approaches to quantify genetic controls for wheat development and improve phenotyping

Hamish Brown, John A. McCallum, Paul A. Johnston, Meeghan D. Pither-Joyce, Richard C. Macknight, Neil Ian Huth, Derrick Jan Moot, Bangyou Zheng, Zhigan Zhao, James Hunt, Enli Wang

The paper updates and validates a model for predicting wheat development by integrating molecular and physiological data, showing it can predict phenological responses to environment and guide genetic studies.
