The shape of cross-section for endosperm tissue in the grain of six-rowed barley (Hordeum vulgare L. emend LAMALK var. Minorimugi) changed through the shortened U-letter form into the grotto form which had a hole in the central part of endosperm with progress in ripening at the first half of ripe stage. The hole in grotto grain contracted with accumulation of photosynthate and decreasing of the moisture content in the grain, then finally disappeared at around 35 % of the moisture content in the latter half of ripening period. The remain rate of grotto grain correlated with the maturing grade, the moisture content and the fresh thousand kernel weight, therefore many grotto grains were found in the green colored immature ear. The soil moisture condition during ripening and the late time of snow melt affected to the developing and disappearance of grotto grain
