Comparison of tikhur genotype by using GGE BI plot

Abstract

Tikhur (Curmuma angustifolia) is one of the herbs mentioned in ancient scriptures of Ayurveda. It is economically and medicinally important product of India as well as Chhattisgarh. The edible rhizome rich in the starch content is processed to obtain tikhur flour. Tikhur production in Chhattisgarh is fairly high. The experiment carried out in Randomized Block Design on Tikhur genotype in Chhattisgarh state of Bastar district during 2015-16 crop years. The objective of the study is to find which genotype the highest yield and most desirable genotype of Tikhur crop in Bastar region. The GGE bi plot graphically displays G plus GE of a MET in a way that facilitates visual cultivar evaluation and mega-environment identification. This technique can serve as a useful tool for recommendation of Tikhur genotype for specific growing region taking into account the specification of genotype and growing conditions. GGE bi-plot analysis depicted the adaptation pattern of genotypes at varied environments and discrimination ability of environments. The IGDMT-10-1(G5) most stable genotype and E5 most suitable environment all the genotype.
