Iron and zinc malnutrition is a global humanitarian concern that mostly affects newborns, children, and women in low- and middle-income countries where plant-based diets are regularly consumed. This kind of malnutrition has the potential to result in a number of immediate and long-term implications, including stunted growth, an elevated risk of infectious diseases, and poor development, all of which may ultimately cause children to not develop to the fullest extent possible. A determination of the contributions from genotype, environment, and genotype by environment interactions is necessary for the production of nutrient-dense lentil varieties that offer greater availability of iron and zinc with a high level of trait stability. Understanding the genotype and environmental parameters that affect G x E (Genotype x Environment) interactions is essential for plant breeding. We used GGE(Genotype, Genotype x Environment interactions) and AMMI (Additive Main effects and Multiplicative Interaction) models to study genetic stability and GE(Genotype x Environment interactions) for grain Fe, Zn, Al, and anti-nutritional factors like phytic acid content in sixteen commercially produced lentil cultivars over several different six geographical locations across India. Significant genetic variability was evident in the Fe and Zn levels of different genotypes of lentils. The amounts of grain iron, zinc, and phytic acid varied from 114.10 to 49.90 mg/kg, 74.62 to 21.90 mg/kg, and 0.76 to 2.84 g/100g (dw) respectively. The environment and GE (Genotype x Environment interactions) had an impact on the concentration of grain Fe, Zn, and phytic acid (PA). Heritability estimations ranged from low to high (53.18% to 99.48%). The study indicated strong correlation between the contents of Fe and Zn, a strategy for simultaneously increasing Fe and Zn in lentils may be recommended. In addition, our research revealed that the stable and ideal lentil varieties L4076 (Pusa Shivalik) for Fe concentration and L4717 (Pusa Ageti) for Zn content, which have lower phytic acid contents, will not only play an essential role as stable donors in the lentil bio-fortification but will also enable the expansion of the growing area of bio-fortified crops for the security of health and nutrition.
铁和锌营养不良是一个全球性的人道主义问题,主要影响低收入和中等收入国家中经常食用植物性饮食的新生儿、儿童和妇女。这种营养不良有可能导致一系列直接和长期的影响,包括生长发育迟缓、传染病风险升高以及发育不良,所有这些最终都可能导致儿童无法充分发育。为了培育出营养丰富的小扁豆品种,使其铁和锌的利用率更高且性状稳定性高,有必要确定基因型、环境以及基因型与环境相互作用所起的作用。了解影响基因型与环境互作(G x E)的基因型和环境参数对于植物育种至关重要。我们使用基因型主效应和基因型与环境互作(GGE)模型以及加性主效应和乘积互作(AMMI)模型,研究了印度六个不同地理位置的16个商业生产的小扁豆品种的籽粒铁、锌、铝含量以及植酸等抗营养因子的遗传稳定性和基因型与环境互作(GE)。不同基因型小扁豆的铁和锌含量存在显著的遗传变异。籽粒铁、锌和植酸的含量分别在114.10至49.90毫克/千克、74.62至21.90毫克/千克以及0.76至2.84克/100克(干重)之间。环境和基因型与环境互作(GE)对籽粒铁、锌和植酸(PA)的浓度有影响。遗传力估计值从低到高(53.18%至99.48%)。该研究表明铁和锌含量之间存在很强的相关性,因此可能建议采用一种同时提高小扁豆中铁和锌含量的策略。此外,我们的研究还发现,铁浓度稳定且理想的小扁豆品种L4076(Pusa Shivalik)和锌含量稳定且理想的小扁豆品种L4717(Pusa Ageti),其植酸含量较低,它们不仅将在小扁豆生物强化中作为稳定的供体发挥重要作用,还将有助于扩大生物强化作物的种植面积,以保障健康和营养安全。
