Canopy temperature: a predictor of sugarcane yield for irrigated and rainfed conditions* [Full subscriber]

Abstract Our recent work with a large genetically diverse sugarcane germplasm (131 clones) grown at different commercial production regions over multiple years with varying water supply (a total of 27 crop cycles) has shown that canopy conductance (gc), and a related easy-to-measure trait, canopy temperature (Tc), when integrated with canopy development, have a strong genetic correlation with crop yield irrespective of the growing condition. In order to exploit this result for variety improvement in the Sugar Research Australia breeding program, three different Tc measurement systems were assessed for their accuracy, genetic correlation of measured Tc with cane yield (tonnes cane…
