Screening of turmeric germplasm for resistance to rhizome rot

Thirty varieties of turmeric Curcuma longa L. were screened in the field against Pythium aphanidermatum for one year during 2016-2017 at College of Horticulture, Anantharajupeta, Y.S.R. Kadapa, Andhra Pradesh. These varieties were also screened in lab and net house (pot) condition. Out of 30 varieties two varieties (Salem and Prathibha) showed resistance to rhizome rot and five (TCP-129, VK-9, IC-330113, IC-033007 and IC-212606) were moderately resistant, providing good material for developing rhizome rot resistant turmeric varieties.
