Genetic diversity of common bean ( L.) ecotypes from Pakistan using Simple Sequence Repeats. | LitMetric

AI Article Synopsis

  • The common bean is a vital legume crop for protein intake among mountain communities in Pakistan, yet it faces underappreciation and reliance on imports from Ethiopia.
  • Biodiversity in the Western Himalayan region includes numerous unexplored landraces, highlighting the need for preservation and sustainable production practices.
  • A research study assessed the biological diversity of 35 common bean varieties from Azad Kashmir, revealing significant genetic diversity and potential for breeding improvements through morphological and molecular analysis.

Article Abstract

Common bean ( L.) is a legume crop grown all over the world and is a very important food of mountain population of Pakistan for protein intake. The Western Himalayan Mountains are rich in biodiversity including unexplored landraces of the common bean crop. Unfortunately, very little attention has been given to this valuable crop in Pakistan, and it is being exported, majorly from Ethiopia, to meet the country's requirements. The exploitation, utilization, preservation and multiplication of existing germplasm within the area are very important for sustainable production of the crop and enhancing the nutrition value for the local community in mountain regions. A research study was conducted for evaluation of biological diversity of common bean landraces from Azad Kashmir and Northern areas of Pakistan using morpho-physiological and molecular markers. Thirty-five common bean ecotypes along with one check variety were collected from different altitudes of Azad Kashmir and Northern Pakistan and screened for biological diversity. Morphological characterization revealed high genetic diversity in parameters including stem anthocyanin, growth type, days to flowering, pods/plant and 100 seeds weight. Genomic characterization using SSR markers, for allelic diversity evaluation among germplasm, also provided diverse profile with 83.3% polymorphism in banding pattern. The bulk of gene pool diversity evaluated within bean landraces may help to initiate breeding program for common bean improvement.
