坐果率高的花穗,一般大小中等,主轴基部穗梗节较密,隆起较高,似鱼鳞排列状,顺序从主轴茎部伸向花穗尾端:支轴具有同样特征,只是穗梗节隆起没有主轴高。葡萄优良穗主轴、支轴均较细且柔软,伸展有力,穗轴呈黄绿色或鲜绿色。坐果后果穗紧凑,籽粒大小均匀,排列有序。抵御温差能力强,一般落果少或不落果。

Spikes with high fruit setting rate are generally medium in size. Spike stems are densely arranged at the base of the spindle, with a high uplift. They appear like fish scales that extend from the stem of the spindle toward the caudal end of the spikes: the spindles have the same characteristics but only the stems Uplift no spindle height. Grapes excellent spike spindle, spindle are thin and soft, stretch strong cob yellow-green or bright green. Fruiting fruit ear compact, uniform grain size, arranged in an orderly manner. Strong ability to resist the temperature difference, usually less or no fruit drop.
