Correlation coefficients (R²) between yield and yield component traits in Caiapo × MG12 interspecific cross

Traits	Plant height	Tillering	Yield	Panicle Length	Sterility
Tillering	0.079
Yield	0.376 **	0.015
Panicle Length	0.548 **	-0.070	0.110
Sterility	0.131 *	0.295 **	-0.244 **	0.119 *
1000-grain weight	-0.172 **	-0.118 *	-0.140 *	-0.056	-0.084

Units: Plant height (cm), Tillering (tiller number per plant), Yield (Kg/Ha), Panicle length (cm), Sterility percentage (number of empty spikelets/total number of spikelets), and 1000-grain weight (grams)
