| dc.description.abstract | This study aims to determine the characteristics of F3 generation corn
plants from F2 free crosses which are expected to be useful as a genetic source for
the formation of new basic populations as selection material to form the desired
varieties. The research was conducted at the Faculty of Agriculture, University of
North Sumatra in June-September 2023 using descriptive statistical analysis
method. Corn seeds used were pre-mixed seeds and taken randomly. The
parameters observed were plant height, stem diameter, number of leaves, stem
diameter, male flowering age, female flowering age, difference between male and
female flowering age, male flower color, female flower color, and stem hair color.
The results showed that the value of phenotypic variation has diverse or broad
criteria on the characters of plant height, number of leaves, stem diameter, male
flowering age and female flowering age. Qualitative observation characters on the
color of male flowers and variations between observations, namely purple and
green colors and on female flowers there are variations in the color of observations,
namely green and white. Qualitative observation characters on stem color have
color variations, namely green and yellow. In qualitative observations of feather
color there is no variation because it only has one color, namely white. | en_US |
