Abstract: Field experiments are conducted with 87 wheat,67 barley and 6 triticale samples to approach the ecologi-cal mutations of their main agronomic characters. The results indicate that the sprouting stage(X1)of wheat and triticale in Japan and in the Loess Plateau arid mountainous region of China tends to be paral-lel. With intensifying drought,plant height(X2)shortens obviously,and ear length(X3)has no marked mutation. On arid lands of China, the 1000 grain weight(X4)of wheat and triticale is similar to that onmoist lands of Japan, but that of barley is higher. There are positive correlations among X1,X3 and X4 of barley in Japan,and among X1,X2,X3 and X4 in China,Later varieties may be high yielded on China drought lands. It is considered reasonable to introduce late variet
