Abstract

Background: Micronutrient malnutrition is a severe peril for wellbeing of humankind, which can be holistically addressed through genetic biofortification. Lentil, proclaim as poor man’s meat can hold a great promise in global biofortification programme. The present study was designed to appraise genetic variability for Fe and Zn content and elucidate the role of Genotype × Environment interaction for delimitation of micronutrient enriched stable lentil genotypes integrating HA-GGE biplot with REML/BLUP. Methods: Grain Fe and Zn content of 44 lentil genotypes grown at three different locations of West Bengal during two consecutive years were estimated for deciphering the G × E interaction combining HA-GGE and REML/BLUP. Result: Results revealed substantial genetic variability for Fe (48.07 to 107.45 mg kg-1) and Zn (38.72 to 60.07 mg kg-1) in 44 lentil genotypes with significant influence of environment and GE interaction. The present study precisely detected ILL-10123 and VL-156 as the ‘ideal’ genotypes for Fe and Zn content, respectively in addition to non-redundant testing location. Identified genotypes and testing location aid in global biofortification programme for upscaling micronutrient concentration in lentil.

评估扁豆（Lens culinaris Medik.）

背景：微量营养素营养不良是人类福祉的一个严重威胁，可通过基因生物强化全面解决这一问题。被誉为 "穷人的肉 "的扁豆在全球生物强化计划中大有可为。本研究旨在评估铁和锌含量的遗传变异性，并阐明基因型与环境的交互作用，通过整合 HA-GGE 双图与 REML/BLUP 方法，确定富含微量营养元素的稳定扁豆基因型。方法：结合 HA-GGE 和 REML/BLUP，对连续两年在西孟加拉邦三个不同地点种植的 44 个小扁豆基因型的籽粒铁和锌含量进行估计，以解读 G × E 的相互作用。结果结果表明，44 个小扁豆基因型中铁（48.07 至 107.45 毫克/千克）和锌（38.72 至 60.07 毫克/千克）的遗传变异性很大，环境与基因型的交互作用影响显著。除了非冗余测试地点外，本研究还精确地发现 ILL-10123 和 VL-156 分别是铁和锌含量的 "理想 "基因型。确定的基因型和测试地点有助于全球生物强化计划提高小扁豆的微量营养素含量。
