title: Genetic variability of pepper (Capsicum annuum L.) seed proteins studied by 2-D electrophoresis with immobilized pH gradients.
abstract: Ten pepper (Capsicum annuum L.) inbred lines were successfully differentiated by two-dimensional electrophoresis with immobilized pH gradients. Qualitative polymorphism of water-soluble and urea/detergent-soluble seed proteins, respectively, was investigated by computer analysis and used for establishing a dendrogram derived from maximum-parsimony analysis. The dendrogram calculated from urea/detergent-soluble proteins shows four types of distance indices, whereas water-soluble proteins show two sets of inbred lines with similar intraset distance indices. The validity of the dendrograms with respect to quantitative inherited traits, such as cold tolerance and earliness, will be tested by field trials.
