Abstract: Studies were conducted to evaluate the locally developed, improved genotype of Brassica napus viz., HS-98, and compared its performance with the established commercial varieties viz., Dunkled, Rainbow, Oscar and Altex. The agronomic traits taken into consideration were siliqua per plant, siliqua length, siliqua width, pedicle length and 1000 seed weight. The biochemical parameters included the percentage of oil in the seed, oleic acid, linoleinic acid, protein and seed moisture. The mean squares for siliqua per plant, siliqua length and 1000 seed weight were significant at 1% level of probability, whereas siliqua width and pedicel length were non significant. HS-98 had maximum number of siliqua per plant (156.0) and siliqua length per plant (6.7 cm) and therefore high yielding among all the genotypes. The seed protein was highest (25.1 %) in HS-98 followed by Rainbow, Oscar, Altex and Dunkled.
