Abstract

Distinct polymorphism in electrophoretic banding patterns of seed protein following SDS-PAGE was noted in 11 guava genotypes, which led to the detection of 23 polypeptide bands. The highest number of bands (16) was observed in RCG-11 followed by Sangam (14), RCG-3 (13), RCGH-7 (12) and least in Lalit (9). The Rm values ranged from 0.097 to 0.958 in the size range of 97.4 to 14.3 kD. Genetic similarity ranged from 52.6 to 90.90 percent among the genotypes. High similarity index value (90.9%) was recorded in between RCGH-4 and Lucknow-49, Allahabad Safeda and Lucknow-49, Allahabad Safeda and RCG-2 were the genotypes, which relatively close The least similarity value (52.6%) was observed between RCG-11 and RCG-3 followed by RCG-11 and RCG-1 (52.90%). In cluster analysis, total seven clusters were formed and genotypes RCG-1, RCG-3, Sangam, RCGH-7 and RCG-11 were monogenotypic in cluster.
