The angle between the leaf blade and stem is small, contributing to a compact plant form. The sheath of the first leaf has medium anthocyanin coloration, and the leaf tip is rounded. Roots at the stem are colored anthocyanin from medium to strong intensity. Tassel flowering occurs in early or medium time, with weak or very weak anthocyanin coloration of the spikelet bracts and stamens. The tassel has sparse or medium-density ears, the main axis is short or medium length and positioned above the upper lateral branch, forming a small or medium angle with lateral branches. Primary lateral tassel branches are straight or slightly curved, short, and few. Silk emergence occurs in early or medium time, with very weak or weak anthocyanin coloration. The ear is medium length, thin, cylindrical, with a short stalk. The number of rows varies from small to medium, and the ear stalk is not colored. The kernel is intermediate type, closer to starchy, with yellow-orange color. These characteristics make NPNU 1629 suitable for cultivation under various climatic conditions, ensuring stable yield and high-quality yellow-orange kernels.
