Evaluation of Coriander Germplasm Against Stem Gall Disease of Coriander (Coriandrum sativum L.)

One hundred two germplasm of coriander (Coriandrum sativum L.) were screened for resistance against stem gall, a severe disease caused by Protomyces macrosporus Unger. Out of 102 germplasm of coriander, thirty five germplasm of coriander showed moderately susceptible reaction to stem gall disease namely ND Cor- 9,13, 14, 15, 18, 19, 20, 22, 23, 24, 25, 27, 34, 38, 49, 60, 61, 64, 65, 67,70, 71, 73, 76, 81, 82, 86, 88,94, 95, 96, 97, 98, 99, 101 whereas, sixty seven germplasm of coriander were observed susceptibility to stem gall disease of coriander e.g., ND Cor- 1, 2, 3, 4, 5, 6, 7, 8, 10, 11, 12, 16, 17, 21, 26,28, 29, 30, 31, 32, 33, 35, 36, 37, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 62, 63, 66, 68, 69, 72, 74, 75, 77, 78, 79, 80, 83, 84, 85, 87, 89, 90, 91, 92, 93, 100, 102. Minimum per cent disease intensity of 27.5% of stem gall disease was recorded in NDCor-18 and NDCor-76 whereas maximum per cent disease intensity of 82.5 was recorded in NDCor-32 showing maximum susceptibility among the germplasm. Rest of the germplasm ranged in between 25.0 - 82.5 % PDI.
