This study was conducted to evaluate growth characteristics, yield and feed value of newly developed domestic teosinte (Geukdong 6) compared to widely cultivated silage corn hybrid (31N27) and sorghum × sudangrass hybrid (P877F). Geukdong 6, a new single cross (Teosinte × Suwon 19) variety, is a teosinte (Zea may L. ssp. maxicana) developed by the Geukdong 6 of agricultural company corporation (GACC) in An-dong province. This field experiment was designed in a randomized block design with three replications and consisted of silage corn (T1), sorghum x sudangrass hybrid (T2) and Geukdong 6 (T3). Leaf length, number of leaves, number of tillers and fresh yield of T3 were higher than that of T1 and T2 (p<0.05). Dry matter yield of T3 was lower than that of T1 (p<0.05). In particular, T3 (0.1 kg/cm2) showed to be very tender compared to other T1 (0.5 kg/cm2) and T2 (0.5 kg/cm2), (p<0.05). The crude protein content of T3 as 8.25% was higher than that of T2 (5.90%), (p<0.05). However, there was no significant differences between T1 (8.14%). The brix degree of T2 was higher than that of T1 and T3 (p<0.05). T3 showed higher content of total minerals compared to T1 and T2 (p<0.05). The relative palatability of T3 was higher than T1 and T2 (p<0.05), when fed to deer as soiling crop. However, it showed a lower than T1 in Korean native cattle and korean native goats. The relative palatability of the silage shown in order of T1> T3> T2 in korean native cattle, spotted deer, and korean native goats. As mentioned above the results, Geukdong 6 (T3) could be recommended as using of soiling and lab silage, when high fresh yield, tender stem, number of many leaf, content of high crude protein, and palatability higher than sorghum × sudangrass hybrid were considered.
