The results revealed that, higher germination and field emergence (88.07 and 79.94 %) was recorded in C4 (KBSH-44) and Z1 (Bangalore and Kolar) (93.07 and 84.80 %). Highest (96.45%) physical purity was found in Morden (C1) and Z1 (97.80 %). Highest (96.50%) genetic purity was recorded in C5 and Z1 (97.33%). Highest (41.33%) oil content was recorded in KBSH-1 (C2) and Z1 (37.48 %). In Morden and KBSH-1, T6 (Thiram @ 3g per kg + Metalaxyl 35 SD @ 2.5g per kg + Imidocloprid 70 WS @ 4g per kg seed treatment (Dry dressing) + Confidar 200 SL (0.1%) foliar spray at 30 DAS and Triazophos 40EC (Hostothion) @ 0.2% foliar spray at 45 DAS) recorded largest head diameter (15.00cm and 18.00cm), 100 seed weight 5.820 and 6.553g), more seed filling (88.86% and 90.00%), higher bulk seed yield per plant (37.93kg and 40.33kg), graded seed yield per plant (35.67 and 37.33 kg) and seed yield (1681.7 and 1773.3 kg/ha, respectively). Same treatment recorded highest germination (96.00 and 95.00%), seedling length (36.11 and 35.44 cm), highest seedling vigour index (3452 and 3366), oil content (34.82and 42.63%) were recorded in both Morden and KBSH-1.ennullThesis
