Boron (B) efficiency of oilseed rape (Brassica napus) and mustard (B. juncea) genotypes was determined on a low B soil at Mt. Compass, South Australia. B efficiency was observed in oilseed rape genotypes, Zhongyou 821, Dunkeld and Zheyou 2, and in mustard genotypes Pusa Bold and CSIRO 6. Genotypes grown in the field were also grown under glass-house conditions, in pots filled with pre-washed sand extracted from the Mt. Compass field site. Two B treatments, one B adequate (0.25 mg B kg−1 soil) and one B deficient (imposed by omission) were used to indicate whether vegetative response to B could predict final yield response and provide a more convenient selection criterion for identifying B-efficient germplasm. Vegetative response of 35 d old (D35) genotypes grown in pot culture closely reflected field response, indicating the expression of B efficiency traits in early growth, and its potential use in selection.
