CULTIVAR VARIATION IN TOTAL NITROGEN UPTAKE IN RAPE

Abstract

Summer rape (Brassica napus L.) cv. Tower contained higher nitrogen contents in the vegetative plant parts at anthesis and maturity, and higher seed protein than cv. Midas when grown under similar conditions. The high protein trait in cv. Tower was directly associated with its greater ability for the uptake and translocation of nitrogen. The differential nitrogen uptake appeared to be inherited.
