A field experiment was conducted during three consecutive Rabi seasons (2002-03 to 2004-05) at Kumarganj, Faizabad, (UP). The coriander genotypes, received from All India Coordinated Research Project on Spices, were tested for resistance against stem gall disease and powdery mildew under natural condition. The promising genotypes were also tested at Dholi (Bihar), Hissar (Hariyana) and KVK and farmers field in Uttar Pradesh. The data on coriander genotypes revealed that genotype K.Selection showed lowest disease severity of stem gall 6.4% in 2002-03, 6.7% in 2003-04 and 6.8% in 2004-05. Whereas, pooled disease severity of stem gall in K.Selection during 2005-08 was 8.62% as compared with Pant Haritma (11.78%), UD-118 (18.78%), RD-154 (33.33%) and LCC-174 (37.46%). The yield performance of K.Selection in coordinated varietal trials at Kumarganj was significantly higher over the national check Pant Haritma. K.Selection also recorded higher seed yield at farmer's field (10.9%) and Krishi Vigyan Kendra (23.5%).
