【 摘 要 】

Corn is one of the carbohydrate-producing plants in addition to rice and wheat which contains nutrients that can be used for humans and animals. Local plants have an important role for genetic resources and can create new varieties. So it needs to be preserved and utilized. The purpose of this research is to characterize the local maize of Siarang Dairi. This research uses qualitative method is descriptive analysis. The data collected include the quantitative and qualitative character of agronomic and morphological characters using 5 plant samples. The results showed that the local Siarang Dairi maize had a root falling percentage of 0% and the stem fall percentage of 3.07%. The high of the plant ranged from 236 - 277 cm. The length of the cob were from 16 - 19 cm with an almost homogen diameter of 4 - 4.5 cm. The uppermost form of cylindrical and cylindrical conical. Grain lengths range from 6 - 8 mm, with grain widths ranging from 5 - 9 mm, and grain thicknesses ranging from 3 - 5 mm. The top grain surface shape is jagged, round, and flat. Specific color grains are unique and varied from brown, orange and red color.
