摘要

培育养分密集的鹰嘴豆品种是解决养分缺乏问题的一个可行方法。免耕是一种可持续的农业耕作方法,有助于减轻气候变化对作物生产力的不利影响。在免耕系统下开发生物强化鹰嘴豆栽培品种可优化这一农业实践的效益,提高生产力和谷物营养质量。本研究对摩洛哥免耕栽培鹰嘴豆的蛋白质、锌和铁含量的遗传变异进行了评估,以筛选出具有优良品质性状的品种。蛋白质(8.08-29.58%)、锌(11.04-35.02 毫克/千克)和铁(17.04-86.58 毫克/千克)含量的遗传变异很大。与蛋白质(15.38%)和铁(10.7%)含量相比,锌含量(65.83%)的遗传率较高,表明该性状具有较高的选择增益潜力。传统耕作的蛋白质和铁含量较高,而免耕的锌含量较高。通过 MGIDI 选育出 22 个鹰嘴豆品种,这些品种可作为免耕条件下蛋白质、锌和铁生物强化的供体。

Genetic variability for protein, zinc, and iron content in a chickpea collection under no-tillage system conditions

The development of nutrient-dense chickpea cultivars is a promising way to cope with nutrient deficiency. No-tillage is a sustainable agricultural practice that can help mitigate the adverse effects of climate change on crop productivity. Developing biofortified chickpea cultivars under no-tillage system could optimize the benefits of this agricultural practice, enhancing both productivity and the grain nutritional quality. In this study, the genetic variability for protein, zinc, and iron content was assessed in a chickpea collection grown under no-tillage system in Morocco in order to select accessions with superior quality traits. Substantial genetic variation was recorded for protein (8.08–29.58%), zinc (11.04–35.02 mg/kg), and iron (17.04–86.58 mg/kg) contents. High heritability value was obtained for zinc content (65.83%) compared to protein (15.38%) and iron (10.7%) content, suggesting high potential selection gain for this trait. Conventional tillage yielded higher protein and iron contents, while no-tillage showed the higher zinc content. MGIDI allowed the selection of 22 chickpea accessions that could be used as donors for protein, zinc, and iron biofortification under no-tillage conditions.

期刊介绍: Genetic Resources and Crop Evolution is devoted to all aspects of plant genetic resources research. It publishes original articles in the fields of taxonomical, morphological, physiological, biochemical, genetical, cytological or ethnobotanical research of genetic resources and includes contributions to gene-bank management in a broad sense, that means to collecting, maintenance, evaluation, storage and documentation. Areas of particular interest include: -crop evolution -domestication -crop-weed relationships -related wild species -history of cultivated plants including palaeoethnobotany. Genetic Resources and Crop Evolution also publishes short communications, e.g. newly described crop taxa, nomenclatural notes, reports of collecting missions, evaluation results of gene-bank material etc. as well as book reviews of important publications in the field of genetic resources. Every volume will contain some review articles on actual problems. The journal is the internationalized continuation of the German periodical Die Kulturpflanze, published formerly by the Institute of Plant Genetics and Crop Plant Research at Gatersleben, Germany. All contributions are in the English language and are subject to peer reviewing.
