Abstract Thirty-four accessions from Zea and 10 accessions from related genera were assayed for the presence of Bg, a transposable element originally found in maize (Zea mays ssp. mays). Bg-like sequences, identified as hybridizing bands on Southern blots, were visualized in all Zea accessions and were present in approximately equal numbers in teosinte and maize. With the exception of Tripsacum dactyloides, all accessions from related genera failed to hybridize with the Bg probes, even at reduced stringency. A comparison of the restriction patterns of related inbred lines revealed numerous common hybridizing fragments. An index of molecular similarity (MS) was used to determine the degree of similarity between pairs of inbred lines. Computed MS values endorse an inbred relationship and are in good agreement with published results of cluster analysis on these inbred lines.
