In the present study aphids density and yield components of 12 genetically diversified Brassica genotypes were determined under field conditions during 2006-08. The genotypes tested were Brassica napus (Westar), B. napus (Ganyou-5), B. napus (Rainbow), B. napus (Oscar), B. napus (Vanguard), B. napus (Crusher), B. napus (Torch), B. napus (Legend), B. napus (Altex), B. juncea (Raya Anmol), B. carinata (Peela Raya) and B. campestris (T-16-401). The results showed that mean aphids density was significantly higher (37.94 aphids plant-1) on Legend and lower (12.84 aphids plant-1) on Vanguard. With respect to yield and its components, highest values for seed yield (2386 kg/ha), plant height (214.3cm)rnand number of branches/plant (19.20) were recorded in Peela Raya, whereas maximum 1000 grain weight (4.80g), siliqua length (8.31cm) and seed/siliqua (23.57 seed) were found in Westar, Ganyou-5, and Oscar, respectively. Overall, among the 12 genotypes Vanguard, Crusher and Legend were the best. Based on comparatively better performance against aphids attack and giving better yield components, Vanguard, Crusher and Legend were found best among the Brassica genotypes.
