Abstract：The relationships between millet grain weight and high -dimensional forms,including the length,diameter,side area and volume of spikes,were examined.The spike geometric features of 9 millet va-rieties were collected using image processing technology,and the spike grain weight regressed respectively to the 4 spike geometric features to establish their linear equations.The determination coefficients of 4 linear e-quations were 0.0786 ~0.7842 for the spike length,0.2686 ~0.7894 for the spike diameter,0.5705 ~0.9176 for the spike side area,0.5527 ~0.9057 for the spike volume respectively.The side area and volume of spikes were 2 important traits of millet,and could be used to accurately predict the spike grain weight of millet.
