The present study aims at assessment of genetic diversity in 43 extra early pigeonpea genotypes with 41 simple sequence repeat markers.
In the present investigation, 41 HASSR markers were used to assess the genetic diversity. Similarity matrices were utilized to construct the unweighted pair group method with Arithmetic average dendrogram using NTSYs PC software.
Out of 41 HASSR markers, 21 markers were showed distinct banding pattern, while 11 markers were showed monomorphic banding pattern and remaining 9 markers showed no banding pattern or not amplified. Cluster analysis done using HASSR markers revealed that ICPL87119 was found to be the most diverse. This genotype also found to be resistant to wilt. Based on similarity coefficients and cluster analysis genotypes ICPL87119, ICPL84031, ICPL88014, ICPL161, ICPL87091 and CORG9701 were genetically more distant from other genotypes studied and these varieties can be used for their desirable characteristics in breeding programs for pigeonpea improvement.
