Abstract

The current research entitled “Analysis of genetic variation among brahmi (Bacopa monnieri) accessions in Andhra Pradesh” was carried out at Dr. Y.S.R. Horticultural University, Horticultural Research Station, Venkataramannagudem, Andhra Pradesh. Genetic variations were evaluated for 22 accessions of brahmi using 20 ISSR markers.PIC value for each ISSR primer was calculated which ranged from 0.089 to 0.992 with an average of 0.678 which showed 95% polymorphism. Average genetic similarity among twenty two accessions ranged from 0.111 to 1.000. Among the 22 accessions studied APBm-3 was found to have the least genetic distance of 0.111 with APBm-22 and showed maximum genetic divergence. The APBm-9 and APBm-12 accessions had a high genetic similarity of 1.000 and showed minimum genetic divergence. Since, genetic variability is essential for the crop improvement it is important to know genetic variation between the accessions. The findings suggested that ISSR primers can be used to identify the genetic relationships between B. monnieri accessions. It is possible to draw the conclusion that knowledge of genetic diversity and genetic similarity among brahmi accessions is essential for their breeding and conservation programmes.

Conclusion

It can be concluded that ISSR markers may be an useful tool for the identification of Brahmi. The present findings can help the genetic variation analysis among different accessions of Brahmi. The accessions showed a considerable level of genetic diversity, indicating a high genetic variability in the population. The genetic variability in a gene pool is normally considered as being the major resource available for breeding programs.
