Description
Summary:All maize inbreds have been classified into heterotic groups based on pedigree information or combining ability. The Lancaster Sure Crop and BSSS heterotic groups are the most commonly used heterotic pair to developing commercial maize hybrids in central and southern Europe. One of the best middle late hybrids was that between B73 (BSSS) and Mo17 (Lancaster). In the present study, we analyzed the means of test cross grain yield, grain yield per se, ear length, number of grain rows, grain mass, cob diameter, kernal length, kernal width and stem rot of 19 maize inbreds derived from Mo17 family. The Mo 17 derivative inbreds are characterized by divergence of all the above traits. Two of the 19 inbreds crossed with the B73-type inbred tester 568 had significantly higher grain yield (P
