| Abstract

:
|
As the first objective, I assessed the genetic diversity of different Capsicum landraces grown in Northeast India. For this purpose, 171 accessions of Capsicum spp. were used. Out of these, 131 accessions were collected from NE states of India. A total of 420 bands were obtained with six primer combination of which 254 (60.48 %) were polymorphic across the dataset. The neighbor joining tree grouped all accessions into two major clusters each of which further divided into two sub-groups. Principal coordinate analysis (PCoA) displayed groupings which were consistent with neighbour joining analysis. Structure results indicated that the sampled accessions belonged to two distinct populations designated as Pop A and Pop B. This study revealed the presence of high diversity in the accessions of NE India which may be due to natural interspecific hybridization and selection pressure due to environmental and anthropogenic factors.
