Abstract
Background: Delineation of high yielding stable lentil genotypes (G) with least environmental (E) influence is a challenging issue. In the present study, an attempt has been made to unravel the magnitude of the effect of GEI for appraising the stable lentil genotypes through deploying HA-GGE biplot along with linear unbiased prediction (BLUP) using restricted maximum likelihood (REML) and other stability indices. Methods: The present experiment was conducted with 30 promising lentil genotypes grown at four different locations of West Bengal during two consecutive years for recording grain yield. Subsequently, G x E interaction was deciphered integrating HA-GGE and REML/BLUP method. Result: Genotypes appraisal detected presence of adequate genetic variability and significant G ´ E interaction. Integration of GGE biplot along with REML/BLUP precisely delineated G30 (IC 521442); G9 (BM 5); G11 (IC 560212) and G8 (Moitree) as stable and desirable lentil genotypes with coherent response across the locations over the years.
