Unveiling Genetic Diversity in Paprika Capsicum spp Using RAPD Markers

Introduction Paprika (Capsicum spp.) is a crucial horticultural crop valued for its culinary and economic significance. Understanding genetic diversity within paprika germplasms can enhance breeding programs and conservation strategies. A recent study utilized Random Amplified Polymorphic DNA (RAPD) markers to analyze genetic relationships among 22 paprika accessions.

Genetic Diversity Analysis in Paprika Germplasms Researchers examined genetic variations and similarities among different paprika species using RAPD-PCR markers. Key findings include:

• 16 ICBD lines showed 100% genetic similarity.
• ICBD 03 had a 76% similarity compared to other ICBD lines.
• CC01 exhibited the lowest similarity with ICBD lines (30%), followed by EC01 (28%) and EC02 (33%).
• The Jaccard’s Similarity Index (JSI) helped construct a UPGMA dendrogram showcasing seven genetic groups.

Significance of Molecular Markers in Crop Improvement Molecular markers, like RAPD, facilitate the classification and improvement of crop plants by:

• Identifying genetic relationships.
• Enhancing breeding programs through precise genetic selection.
• Assessing polymorphism within species.
