Abstract :
Field screening studies were conducted over a period of one year i.e. 2016-2017 in augmented block design with 120 available germplasm lines of turmeric (Curcuma longa L.) at College of Horticulture, Anantharajupeta. These lines were screened against the rhizome rot caused by Pythium graminicolum and Fusarium solani under natural conditions. The severity of rhizome rot is ranged from 0.00 to 92.86 per cent irrespective cultures screened. Among the germplasm cultures screened, cultures like IC-319341, Tenali Kasturi, VK-23, GS, IC-420606, IC-033007, IC-211641, PTS-8, Vikici, Dhindigam, ACC-48, Sonia, NB-60, Kasturi in short duration group, Prathibha, Thodupuztha, KTS-9, Prasangali, ACC-79 in medium duration group and NH-1, Ranga, Salem, Salem-2, Wagon, PTS-12, CL-8, CL-9, CL-10, CL-3, CL-4 in long duration group were resistant to rhizome rot showed 0.0% diseases incidence. More disease incidence (susceptible reaction) of rhizome rot was observed in long duration group.
