Abstract：Aiming at determining the differences in heading date between the main spike and tiller spikes of barley and the resultant effects on barley spike characters,the current research investigated heading dates of the main spikes and different tiller spikes of a two-rowed and a six-rowed barley variety,as well as their spike characters.The two barley varieties both showed differences in heading date between main spike and tiller spikes.With the delay of heading date,spike length,kernel number per spike,and thousand-ker-nel weight all showed a downtrend.The differences in heading date between the main spike and the 1st and 2nd tiller spikes were rela-tively small.Thus,to achieve a high yield of barley,the density of basic seedlings should be controlled at an appropriate level,and the optimal number of tiller spikes per plant is around two.
