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

每穗总粒数与结实一次枝梗数和现存二次枝梗数均密切相关。

There is a significantly linear relation between secondary branch 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 secondary branch per panicle, spikelets in secondary branch per secondary branch, 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。
