To identify the relative performance of yield compenents of wheat in South Huang-Huai River,28 wheat varieties( lines) collected from winter water group on the South Huang-Huai River from 2011 to 2012 were studied by correlation and path analysis. The results showed that: the coefficient of variation of yield components: 1000-grain weight > grains per spike > spikes; correlation between yield components and yield: spikes > grains per spike > 1000-grain weight. The results of partial correlation analysis sho...
