Stability analysis of short duration rice genotypes in Telangana using AMMI and GGE Bi-plot models

In order to identify stable short duration rice genotypes across different agro-climatic zones in Telangana state, Additive Main Effects and Multiplicative Interaction Models (AMMI) GGE Bi-plot analyses was performed. Analysis of variance clearly revealed that contributed highest (34.57 %) followed by environments (32.31 genotype environment interaction (17.10 total sum squares indicating very greater role played genotypes, their interactions realizing final grain yield. AMMI analysis viz., KNM 2305 (G12), 2307 (G16) JGL 20776 (G9) were recorded higher mean yield with positive interactive principal component 1 (IPCA1) scores whereas, RNR 23595 (G5) plotted near zero IPCA1 axis relatively more performance locations. However, the view depicts RDR 1188 (G6) (G12) known as highly unsteady Among environments, Rudrur (E4), Kunaram (E2) Rajendranagar (E5) locations identified ideal realize good yields whereas Jagtial (E1), Kampasagar (E3) Warangal (E6) poor most discriminating. six locations, similar (E2), though they belong (E1) location seems be little divergent. Further, US 314 (G17) performed better at while MTU 1010 (G8) found have (E4) The results conclude high yielder but unstable KPS 6251 (G15) reasonably over
