摘要
高温和干旱是全球小麦生产力的两个重要制约因素;了解在苛刻的生产条件(干旱和高温)下小麦品质参数的基因型反应对于开发营养丰富的小麦品种非常重要。在 2020-21 年期间,对 15 个现代面包小麦(Triticum aestivum L. subsp.通过 AMMI 和 GGE Biplot 分析,利用多环境试验评估了基因型在产量、营养和品质参数方面的稳定性能。我们发现了谷物锌含量(Zn)和铁含量(Fe)的有趣胁迫动态。在热胁迫下,锌含量会增加,但在干旱胁迫下会减少,而铁含量则相反。在终期热胁迫下选择锌、淀粉和籽粒重量可提高产量。蛋白质含量与产量成反比,因此育种者很难优化这两个性状。在所有环境中的 G × E 相互作用和稳定性指数发现,高产稳产基因型 G12(MP1358)(42.09 ppm)和 G5(HI1544)(42.41 ppm)的铁含量较高。G12(MP1358)(14.98%)的蛋白质含量最高。同时,在锌含量方面,G11(MACS 4058)(45.23 ppm)和 G15(WH730)(42.44 ppm)在各种环境中表现最佳。G7(HI 1636)和 G12(MP1358)因其在产量、蛋白质、锌和铁含量方面的高潜力和稳定性而成为双赢基因型。我们的研究表明,在高温和干旱胁迫条件下,小麦籽粒品质和微量营养元素含量之间存在复杂的关系,并可能为有针对性的育种计划提供建议,从而在不造成产量损失的情况下改善小麦籽粒品质和微量营养元素含量。
Multi-Environment Analysis of Nutritional and Grain Quality Traits in Relation to Grain Yield Under Drought and Terminal Heat Stress in Bread Wheat and Durum Wheat
Heat and drought are two important constraints to global wheat productivity; understanding the genotypic responses for quality parameters under harsh production conditions (drought and heat) is very important for developing nutrient-dense wheat varieties. A set of 15 modern bread wheat (Triticum aestivum L. subsp. aestivum) and durum wheat (Triticum turgidum subsp. durum) cultivars were tested in nine environments, including three different production conditions (normal, heat and drought) during 2020–21. Genotype stability performance for yield, nutrition and quality parameters is assessed using multienvironment trials through AMMI and GGE Biplot analysis. We discovered intriguing stress dynamics in grain zinc content (Zn) and grain iron content (Fe). Under heat stress, zinc concentration increases but decreases under drought stress, while iron does the opposite. Selecting zinc, starch and kernel weight under terminal heat stress can boost yield. Protein content and yield are inversely related, making it difficult for breeders to optimise both traits. G × E interactions and stability indices across all environments have found genotypes with high-yielding stable genotypes, G12 (MP1358) (42.09 ppm) and G5 (HI1544) (42.41 ppm) have high Fe content. G12 (MP1358) (14.98%) ranked highest in protein concentration. Meanwhile, for Zn content, G11 (MACS 4058) (45.23 ppm) and G15 (WH730) (42.44 ppm) were top performers across environments. G7 (HI 1636) and G12 (MP1358) stand out as a win-win genotype for their high potential and stability in yield, protein, Zn and Fe content. Our study shows the complex relationships and possible suggestions for targeted breeding programmes under heat and drought stress conditions to improve wheat grain quality and micronutrient profiles without yield loss.
期刊介绍:
The effects of stress on crop production of agricultural cultivated plants will grow to paramount importance in the 21st century, and the Journal of Agronomy and Crop Science aims to assist in understanding these challenges. In this context, stress refers to extreme conditions under which crops and forages grow. The journal publishes original papers and reviews on the general and special science of abiotic plant stress. Specific topics include: drought, including water-use efficiency, such as salinity, alkaline and acidic stress, extreme temperatures since heat, cold and chilling stress limit the cultivation of crops, flooding and oxidative stress, and means of restricting them. Special attention is on research which have the topic of narrowing the yield gap. The Journal will give preference to field research and studies on plant stress highlighting these subsections. Particular regard is given to application-oriented basic research and applied research. The application of the scientific principles of agricultural crop experimentation is an essential prerequisite for the publication. Studies based on field experiments must show that they have been repeated (at least three times) on the same organism or have been conducted on several different varieties.
