Genetic Analysis of Some Commonly Grown Genotypes of Maize in Pakistan Using Maize Specific Simple Sequence Repeat (SSR) Primers

並列摘要


Maize (Zea mays) belongs to the family gramineae (poaceae), genus Zea and speciesmays. The genome of maize comprises approximately 2500 million base pairs. During the present study, maize specific Simple Sequence Repeat (SSR) primers were used to estimate genetic distances among fourteen varieties/genotypes of maize commonly cultivated in Pakistan. On an average, 3.2 alleles per genotype were amplified. Average genetic distance estimated using the four SSR primer sets ranged from 0 - 53%. Dendogram based on DNA data showed that the fourteen genotypes were clustered in six groups A, B, C, D, E and F comprising 3, 4, 2, 2, 2 and 1 genotypes respectively. It has been concluded that genotypes 6098 and Ev-1097 were most distantly related to each other.
