南京林学院叶培忠教授于６０年代初通过中国马褂木与北美马褂木有性杂交选育的杂交马褂木，经在长江流域诸大城市栽培，表现出明显的杂交优势。与中国原种比较，生长期长一个月，材积生长量大１３２％，具有抗高温、抗日灼和抗二氧化硫污染的能力。９０年代初引进淮河流域的大别山区，生长表现良好。今后应继续开展北移驯化和向黄河流域中、下游城市试种推广研究工作。
In the early 1960s, Professor Ye Peizhong of Nanjing Forestry College demonstrated hybrid vigor by cross-breeding of hybrids of Chinese Lolium perfoliatum and North American Lolium perfoliatum in the major cities of the Yangtze River valley. Compared with the Chinese original species, the growth period of one month, volume growth of 132%, with high temperature, anti-sunburn and anti-sulfur dioxide pollution. The early 90s the introduction of the Huaihe River Dabie Mountains, good growth performance. In the future, it is necessary to continue to move northward and domestically and promote the research of popularization and cultivation in the middle and lower reaches of the Yellow River valley.
