A Giemsa C-banding method was used for the identification of somatic chromosomes and heterochromatic knob position in Korean indigenous waxy com (Zea mays L.). 5 inbred stocks were examined and their heterochromatic knob numbers ranged from 6 to 12. In comparison of homologous chromosomes of two stocks of YS-1 and MY-1, knob numbers, knob positions, arm ratios and relative length of chromosomes were different between the genotypes. The length of homologous chromosomes in YS-1 were generally larger than those of MY-1. The Giemsa method was proved to be useful for the identification of somatic chromosome and a C-banded diagram showing knob positions, arm ratios and relative length of chromosome could be used as a good tool to compare the characteristics of chromosomes of Korean indigenous waxy corn stocks.

A Giemsa C-banding method was used for the identification of somatic chromosomes and heterochromatic knob positions in Korean indigenous maize(Zea mays L.). Total of 10 inbred stocks were examined and their knob numbers ranged from 6 to 12. In comparison of homologous chromosomes of two stocks of Waesungri and PI 213749, arm ratios and relative length of chromosomes were different between genotypes. In comparison of arm ratios, all the homologous chromosomes except chromosome 2 were different each other. In comparison of relative length of chromosomes, that of chromosome 1 in Waesungri and PI213749 was 223.22 and 192.03 respectively. The relative length of homologous chromosomes in Waesungri were generally lager than those of PI213749. A C-banded diagram showing knob positions, arm ratios and relative length of chromosome could be used as a good tool to compare the characteristics of chromosomes of Korean indigenous maize stocks.

A Giemsa C-banding method was used for the identification of somatic chromosomes of Korean indigenous maize(Zea mays L.). Two Korean indigenous maize stocks and an American hybrid maize for comparison were examined. Ten deeply stained heterochromatic knobs whose position and size were different between the genotypes, two satellites and interstitial bands were observed. The length of homologous chromosomes compared by the relative lengths of chromosomes presented as a percentage of the length of chromosome 10 were different between the genotypes. The Giemsa method proved to be useful for the identification of somatic chromosomes and for the characterization of different stocks of Korean indigenous maize.
