摘　　要：Fifteen turmeric genotypes from the germplasm held at National Root Crops Research Institute Umudike, Nigeria, were evaluated during the season of 2012-2013 at four locations-Jos （8.3833°N, 7.1833°E, 1,200 m a.s.l.）, Otobi （7.11667°N and 8.08333°E）, Umudike （5.4758°N, 7.5489°E） and Igbariam （6.4°N and 6.93333°E）-in order to select high yielding and stable turmeric cultivars with good quality for release in Nigeria. At each location, the experiment was laid out in randomized complete block design （RCBD） in three replications. Plot size was 9 m2. Data were collected on sprout count, plant height, number of tillers, number of leaves, main pseudo stem girth, rhizome number and weight. Analysis of variance was carried out on the combined data using GenStat Discovery Edition software. Results based on the combined data from four locations indicate that turmeric genotypes did not vary in percentage emergence and number of leaves. However, they varied in height, main pseudo stem girth, tillering, number and yield of fresh rhizomes. The effect of location on all attributes was significant （P 〈 0.05） with Jos location giving consistently the least values for all attributes thus suggesting that this location may not be suitable for the commercial production of turmeric. Genotype by environment interaction for most attributes was not significant indicating that the genotypes responded the same way across the locations. Ten genotypes, viz., UT39, UT44, UT46, UT58, UT50, UTI4, UT41, UT6, UT38 and UT35, are identified as promising and require further evaluation as pre-condition for nomination for official release to farmers.
