Screening of Some Recently Developed Coriander Varieties against Stem Gall Disease Caused by Protomyces macrosporus

Manzoor Raiees Khan and Ghazala Parveen

Twenty-seven varieties of coriander were evaluated for their resistance against stem gall disease caused by Protomyces macrosporus. Out of 27 varieties screened only four varieties viz., UD-125, UD-317, UD-749 and Rlr- 480 having less than 10% stem gall intensity were graded as resistant. The mean yield of healthy seeds was found between 1.33 to 1.97 g/plant and of diseased seeds was between 0.13 to 0.68 g/plant. Average seed yield loss (%) ranged between 6.04 to 27.87%. Minimum yield loss was recorded in UD-125 and maximum in American green.
