우리나라 찰옥수수 및 종실용 옥수수 품종들의 교배친인 11개의 자식계통의 유전적 다양성 및 계통간 유연관계를 50개의 SSR 마커를 사용하여 분석한 결과는 다음과 같다. 1. 50개의 SSR primer들은 찰옥수수 및 종실용 옥수수 품종들의 교배친인 11개 자식계통들에서 총 171개의 대립단편을 증폭시켰고, 각 SSR primer들에서 증폭된 대립단편의 수는 최소 2개에서 최대 6개의 범위로 나타나 SSR loci당 평균 3.4개가 증폭되었으며, 유전
In maize, knowledge of genetic diversity and genetic relationships among elite inbred lines is an significant impact on the selection of parental lines for hybrid varieties. Genetic diversity and genetic relationships among 11 parental inbred lines of Korean waxy and normal corn varieties were analyzed using 50 SSR markers distributed over the whole genome. A total of 171 allele bands were detected with an average of 3.4 alleles per locus. Number of allele bands per locus ranged from two to six and gene diversity varied from 0.165 to 0.900 with an average of 0.596 depending on the SSR loci. The cluster tree recognized three major groups with 61.6% genetic similarity. Group I includes 7 inbred lines (KL103, HW1, HW4, HW6, HW7, HW8, HW9), with similarity coefficients of between 0.616 and 0.730. Group II includes 2 inbred lines (HF1, HF2), with similarity coefficients of 0.959. Group Ⅲ includes 2 inbred lines (HW3, HW5), with similarity coefficients of 0.713. The present study indicates that the SSR markers chosen for this analysis are effective for the assessment of genetic diversity and genetic relationships among 11 parental inbred lines.
