There is a significantly linear relation between secondarybranch grain number and grain number per panicle, and they have the same changing tendency.
穗粒数与二次枝梗粒数随品种的变化是一致的，二者有极显著的 线性相关。

Generally, spikelets per panicle were more closely correlated with number of secondarybranch per panicle, spikelets in secondarybranch per secondarybranch, and spikelet density.
总体上，每穗颖花数与每穗二次枝梗数、每个二次枝梗上的颖花数、颖花密度有更大的相关性。

Total grain number per spike correlated closely to fruiting primary rachis branch number and existing secondary rachis branch number.
