Abstract:
Thirty five finger millet genotypes were evaluated using ISSR markers to study the genetic diversity in finger millet varieties. The study was conducted at the Forest Biotechnology laboratory, College of Forestry, Navsari Agricultural University, Navsari, Gujarat, India. The genetic variability among the 35 finger millet genotypes were studied in an initial screening using 60 ISSR primers. Fifteen of the 60 primers were produced informative, polymorphic products. Polymorphic information content (PIC) value ranged from 0.13 to 0.57. The highest PIC value observed for primer UBC-811 (0.57). The Jaccard’s similarity coefficient obtained in this study ranged from 0.47 to 0.90. The maximum genetic similarity was found between the genotypes, VL-314 and PR-202 (0.90). The minimum genetic similarity was found between the genotypes, KOPN-235 and GN-5 (0.47). The information obtained in this study is useful in choice of related or diverse parents and genetic constitution of genotypes without any environmental influence.
