To get basic information on the Korea local corn lines collected from Busan and Gyungnam Province, a total of 49 lines were classified by the principal component analysis method. The lines were classified into 4 lineal groups by the taxonomic distance. Croup I included 11 lines, and groupII, groupIII and groupIV included 20 lines, 14 lines and 4 lines, respectively. Four groups could be characterized as follows: Croup I : early maturity, short plant, small ears, small kernels, low tillering and medium yielding. Croup II : early maturity, tall plant, large ears, large kernels, multi-ears, low tillering and high yielding. GroupIII: late maturity, short plant, small ears, small kernels, high tillering and low yielding. Croup W medium maturity, tall plant, large ears, small kernels, prolific ears, high tillering and higher yielding.
