Genetic dissection of seed yield and yield-related traits in Brassica napus grown with contrasting nitrogen supplies.

ABSTRACT: Oilseed rape (B. napus) is the main oil crop in China as well as in the world. Nitrogen (N) deficiency significantly reduces the seed yield of B. napus. However, a very few studies involved in the genetic mechanism of seed yield and SY-related traits of B. napus in response to N deficiency. In this study, plant height (PH), branch number per plant (BN), pod number per plant (PN), seed number per pod (SN), 1000-seed weight (SW), and seed yield per plant (SY) were investigated using a B. napus double haploid (BnaTNDH) population derived from a cross between cultivars "Tapidor" and "Ningyou7" grown at an optimal N (ON) and a low N (LN) supplies in three-year field trials. Great variations of SY and related traits were observed in BnaTNDH population un
