Appraisal of Rapeseed Genotypes for Yield Traits and Oil Quality under Swat Valley Condition

Abstract

Eight rapeseed genotypes were evaluated for agronomic parameters, yield, oil quantity and quality. Significant differences were observed for all the parameters except oil and protein percentage. The genotype PI-26369 outperformed the rest of genotypes in yield potential (3118 kg ha^-1), followed by PI-26337 (2422 kg ha^-1). For yield contributing characters like 1000 seed weight, Seed pod^-1 and pods plant^-1, genotype PI-26369 again showed good results that are, 4gm, 20 and 343 pods plant^-1, respectively. The genotype H-19 showed low glucosinolate (54.9 µmol/g), genotype PI-26369 have lowest amount of erucic acid (21.8 µmol/g) and higher amounts of oleic acid (48.09 %). Due to its high yield and oil quality, the genotype PI-26369 is recommended for general cultivation in the area and further use in breeding programmes for Brassica Juncea.
