Crop characteristics of 136 foxtail millet (Setaria italica BEAUVOIS) resources collected in
South Korea were investigated in order to establish basic informations for crop breeding. Spike types of
136 genetic resources were classified as 5 types (conical, clavate, fusiform, cylindrical and top diverge).
Among them, conical type was showed the highest percentage (41.2%). Seed of 136 resources was yellow
color. Spike color of 136 genetic resources were classified as 6 colors (dark brown, light brown, red
brown, yellow, yellowish brown and yellowish white). Yellowish white color showed the highest percentage(
33.8%) among them. Leaf color of 136 genetic resources were classified as 6 colors (brown, dark
green, green, green brown, light green and light brown). Green color was showed the highest percentage(
44.9%) among them. Culm length showed a wide variation from 112cm to 183cm (average is
153.8cm) and spike length from 17.7 to 41.2cm (average is 24.1cm). Days from seeding to heading date
and days from seeding to physiological maturity were showed the range from 63 to 111 days (average is
90.3 days) and the range from 119 to 149 days (average is 117.7 days) respectively. Number of grains per
spike and 1000 grain weight were showed the range from 2,197.0 to 16,980.0 grains (average is 5,839.1
grains) and from 0.6 to 3.1 g (average is 1.79g) respectively. Days from seeding to heading date and days
from seeding to physiological maturity showed highly significant positive correlation coefficient with
culm length, while those were significant negative correlation coefficient with 1000 grain weight.
