Delineation of Stable High Yielding Lentil Genotypes Through HA-GGE and REML/BLUP Method for Gangetic Alluvial Zone of India

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.

Genotype × Environment Interaction for Appraisal of Iron and Zinc Rich Stable Genotypes in Lentil (Lens culinaris Medik.)

“…Lentil (Lens culinaris Medik.) is one of the healthiest pulses rich in starch, proteins, dietary fibres and notably essential micronutrients including Fe, Zn, selenium (Se), folate (vitamin B9), as well as several other dietary nutrients (Bhattacharya et al, 2022a). The recommended daily allowance (RDA) for Fe and Zn can be substantially met by incorporating 100 g of lentils into the daily human diet (Bhattacharya et al, 2022b).…”
