Hepper) using SDS-PAGE of seed storage proteins JF - Research in Biotechnology JA - RIB VL - 7 IS - 0 SE - Research Articles DO - 10.19071/rib.2016.v7.2863 UR - https://www.updatepublishing.com/journal/index.php/rib/article/view/2863 SP - AB - <p><strong>Total seed storage protein profiles of 20 urdbean genotypes including the popular variety T9 were analysed by Sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). 14 genotypes could be clearly identified based on genotype-specific seed protein fingerprints while rest of the test genotypes were categorized into three protein types. Dendrogram based on electrophoretic data clustered the genotypes into seven groups at 78.5% phenon level.  TU 95-1 with TU 12-25-4 revealed lowest similarity index value (0.33) followed by TU 95-1 with PU 30 and KU 96-3(SI=0.35). Clustering pattern revealed distinctly divergent group formed by TPU 95-1 and TPU 4. These may serve as a valuable source genotype in recombination breeding.   </strong></p><p><strong>Key words: </strong>Seed storage protein profiling, SDS-PAGE, Genetic variation, urdbean.<strong></strong></p> ER -
