Sunmang' is a new rapeseed (Brassica napus L.) of F₁ hybrid with high yield and high quality for oil and meal. This hybrid was developed from the cross between Mokpo-CGMS (male sterile line) and 84055-B-10-3-1-6 (restore line) in 1996. It was a

The purpose of this study was to investigate the magnitude of commercial heterosis for seed yields in oilseed rape to determine the potential advantage of hybrids, especially to observe morphological charactes which may influence seed yields. Field tests
