Genotypic x Environment interaction and stability analysis in turmeric (Curcuma longa L.)

Seventeen genotypes of turmeric (Curcuma longa L.) were grown during two consecutive seasons during 2007-08 and 2008-09 at two locations i.e. Main Experiments Station, Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad, U.P and Krishi Vigyan Kendra, Masodha, Faizabad, U.P, for their stability analysis for yield and yield components like weight of mother rhizome (g), weight of primary rhizomes per plant (g), weight of fresh rhizome per plant (g), rhizomes yield (q/ha), dry matter (%), curcumin (%) and oleoresin (%). Mean square due to environment and linear were expressed highly significant for all the traits except curcumin and oleoresin per cent. Linear components of genotypic × environment interaction assumed importance for weight of mother rhizome, weight of primary rhizome per plant and dry matter. Genotypic ×Environment interactions were found to be significant for all the characters except rhizome yield, curcumin and oleoresin. The pooled deviation was found to be significant for weight of mother rhizome and weight of fresh rhizome per plant. | Genotypic x Environment interaction and stability analysis in turmeric Curcuma longa L.
