Abstract

A study was conducted in 22 turmeric cultures to evaluate the level of variability, associative relationship of yield and its contributing traits along with direct and indirect effects of 15 quantitative traits. All the turmeric cultures (22 nos.) for evaluation purpose were collected from various geographical regions of India to examine the variations among them and to study their performance and suitability for Coimbatore condition. The experiment was laid out in Randomized block design with three replications at the Department of Spices and Plantation Crops, TNAU, Coimbatore. Availability of high yielding varieties of turmeric for particular locality are limited and identification of contributing characters towards yield is needed for the selection of varieties with high yield. Owing to clonal propagation, self-incompatibility and self-sterility, availability of natural genetic variation in turmeric is reported to be narrow. Among the 15 quantitative traits studied, many of the char
