Description Under field conditions, 38 coriander genotypes were screened against powdery mildew disease during Rabi 2021-22. Out of these none of the genotype was found free from disease. Genotype NCOR-124 had the lowest intensity of the disease by 32.69%, while which was at par with genotype NCOR-122 (33.11%). In the context of the disease reaction, none of the genotypes showed resistant reaction; only two genotypes, NCOR-124 and NCOR-122, were found moderately resistant, and six genotypes, COR-129, COR-132, COR-15, Rcr-475, Rcr-480, and Rcr-684, were found susceptible to powdery mildew disease under field conditions. Early flowering was observed in genotypes NCOR-124 and NCOR-122 which initated at 38 and 39 days after sowing (DAS), respectively. Similarly, early maturity was also observed in both the genotypes at 87 and 88 DAS, respectively. While late flowering was observed in genotype NCL-13 and Rcr-475 at 57 DAS, while late maturity was observed in variety Rcr-684 at 104 DAS. The leaf area of among genotypes was recorded in ranged from 2.34 to 7.12 cm2. Highest leaf area of 7.12 cm2 was recorded in genotype NCOR-144 and lowest leaf area 2.34 cm2 was recorded in genotype Hissar Anand. Maximum plant height (75.34 cm) was measured in genotype GDLC-1, while it was lowest (49.43 cm) in genotype NCOR-103. Genotypic correlation analysis of various morphological characters against powdery mildew disease intensity showed a highly significant positive correlation between maturity (r = 0.529), plant height (r = 0.492), and flower initiation (r = 0.317), but no significant negative correlation was observed with leaf area (r = -0.079). It has also been identified that genotypes that showed characteristics of early maturity had a resistant response.
