Abstract:
Coriander is an annual seed spice crop, which belongs to family Apiaceae. It is native of Mediterranean region. The aromatic characters of plants are due to presence of linalool compound in essential oil of seeds. The green leaves of coriander are used in salads and are a good source of vitamin A and vitamin C. Powdery mildew of Coriander (Coriandrum sativum L.) caused by Erysiphe polygoni DC. Has become a serious and widespread problem in many parts of India, including Rajasthan. In order to manage air borne pathogens of coriander, resistant varieties serve as an eco-friendly approach. Field screening of coriander genotypes against this disease a study was conducted in agronomy research farm, Department of Plant breeding & genetics. Coriander one hundred twenty eight (128) accessions were screened to find out resistant sources against powdery mildew of coriander. Disease intensity (%) for coriander germplasm lines was calculated 110 days after sowing. Screening of germplasm lines revealed that minimum disease intensity of 32.40% was observed in UD-39 and maximum was found in UD-81 (92.40 %). Powdery mildew score ranged from 0.0 (free) to 5.0 (highly susceptible), 7 genotypes found moderately resistant, 31 genotypes showed susceptible and 90 genotypes comes under highly susceptible. Despite being high susceptible, some test entries produced good yield and showed tolerance to powdery mildew disease. Resistant genotype could be utilized as donar parent for powdery mildew resistance breeding programme. None of the line was found completely resistant against powdery mildew.
