Values followed by the same letter are not significantly different at 5% level of LSD test.
PHT = plant height; RTR = percent reproductive tillers; DH = days to 50% heading;
DPM = days to 50% physiological maturity; KWT = kernel weight; EAR = ear length;
SPK = spikelets per head; SF = sterile florets per head; TL= tillers per plant.
