Abstract

The genotype x environment (G X E) interaction effects for glucosinolate, free fatty acids (FFA), iodine value and oil content in rapeseed were studied on the basis of four year data. Fourteen cultivars including seven European were grown during rabi 1996–97 to 2000–2001 in a randomized block design with three replications. The G X E interaction was significant for all the biochemical traits except iodine value. The cultivar Topa possessed minimum glucosinolate content (36.25 mmol/g defatted meal), maximum FFA (1.99) and 39.25 per cent oil content. The cultivar DGS 1 and two European cultivars viz., Karat and Legend contained medium mean glucosinolate content, bi»0 and S2di»0. These cultivars were designated as stable and widely adapted for glucosinolate.
