| Abstract: | Common bean (Phaseolus vulgaris L.) is considered as one of the principal grain legume crops grown in north-western Himalayan state of Jammu and Kashmir (J&K), India. Huge diversity has been observed for this crop in state Jammu and Kashmir. The hilly regions of the state J&K are famous for producing high quality, tasty and highly flavoured beans. In order to characterise this huge diversity and trace the origin of common bean, systematic efforts have been made for the first time in collection, evaluation and characterization of bean collection from Jammu & Kashmir. A set of 428 common bean lines were initially collected/procured and based on cluster analysis using few qualitative traits/site of collection, a diverse set of 96 lines was selected. The PCR assay for phaseolin locus led to the characterization of 96 lines into Meso-american and Andean types. Out of 96 lines tested, 45 possessed “S” type phaseolin and 51 possess “T” type phaseolin. The ITS region of selected local and exotic lines was Sanger sequenced and the sequence analysis of ~ 800 bp long region revealed the presence of 12 SNPs including one promising SNPs showing significant association with phaseolin patterns. The clustering based on ITS sequence data led to the clear cut separation of common bean lines into two distinct clusters based on their phaseolin types. The results of the present study helped to gain insights into the origin of common bean landraces grown in state of J&K, India. |
