Performance of turmeric (Curcuma longa L.) genotypes for yield and yield attributing traits under high altitude conditions of Andhra Pradesh

Abstract

The present experiment was conducted in randomized block design with three replications during Kharif 2014-15, 2015-16 and 2016-17 at Horticultural research Station, Chintapalli. Total 12 genotypes were taken for study including one local check and one national check. Observations were recorded on various growth and yield characters. Analysis of variance revealed that a wide range of variation was observed for all the characters under the study except for leaf width. Among the genotypes, PTS-12 recorded the highest plant height (130.78 cm) followed by PTS-55 (125.16 cm) whereas SLP 389/1 recorded the lowest plant height (84.91 cm) followed by ACC-48 (85.07). The genotype NDH-98 recorded highest yield (53.76 t/ha) followed by NDH-8 (41.36 t/ha). NDH-98 also recorded highest dry recovery percentage (23.13) followed by PTS-8 (22.35). Thus, these genotypes may be recommended for commercial cultivation under high altitude and tribal area of Andhra Pradesh. They can be further evaluated to identify best genotypes suitable for cultivation at other locations and further used in breeding programmes.
