[Effects of nitrogen application on yield and nitrogen use efficiency of rapeseed (Brassica napus)].

A greenhouse pot experiment was conducted to study the effects of nitrogen application on the yield and nitrogen use efficiency of rapeseed under post anthesis waterlogging condition. Two high nitrogen use efficiency rapeseed genotypes 'Monty' and 'Xiangyou 15' and two low nitrogen use efficiency rapeseed genotypes 'R210' and 'Bin270' were treated with 3 nitrogen levels (0.05, 0.

Molecular validation of multiple allele inheritance for dominant genic male sterility gene in Brassica napus L.

Dominant genic male sterility (DGMS) has been playing an increasingly important role, not only as a tool for assisting in recurrent selection but also as an alternative approach for efficient production of hybrids. Previous studies indicate that fertility restoration of DGMS is the action of another unlinked dominant gene. Recently, through classical genetic analysis with various test populations we have verified that in a DGMS line 609AB the trait is inherited in a multiple allelic pattern.
