Agronomic performance of dihaploid lines of Brassica napus in Chile.

摘要

Information is given on the agronomic performance of 8 selected dihaploid lines obtained via microspore culture from F1 donor plants originating from winter type X spring type rape crosses. The value of this procedure for rape breeding programmes isnoted. Two of the dihaploids (DH024 and DH010) produced grain yields which were not statistically different from the highest yielding control cultivar Tornado, and also performed well for percentage oil content. They are 100% homozygous and are well adapted to the productive conditions of Chile.
