“…The focus of this study was the quantitative analysis and research and technological trends in the area of Biotechnology in agriculture and agro-industry. Despite international comparisons, the current study indicated a notable increase in the number of publications and patents at the international level in recent years, because, in the agricultural and agricultural sector, biotechnology has played an important role in sustainability of production [53], through the development of technologies that promote conserving soil characteristics, increasing crop productivity and increasing pest resistance [54].…”

This article presents Scientometrics as a major element in quantitatively addressing the study of a field of knowledge. This study seeks to combine complementarily and integrally the bibliometry with the technological outlook to obtain an image of the current state of biotechnology in a specific area. This contributes with a trend-setting in a socially relevant sector that currently addresses global challenges such as climate change and energy and food security. Through a bibliometric study, it determines the dynamics of the scientific production, key authors, country participation and language trends in the domain of Biotechnology in the agricultural and agro-industrial sectors. In addition, a technological outlook is presented, in which, based on the analysis of trends in patents, the innovative state of the area is established. The main result is associated with the dynamics of scientific production, which according to the Lotka law; states that the percentage of authors who produce N articles is inversely proportional to a power of N. The technological outlook is consistent with the Latin American studies, concluding that, despite of the increasing dynamics, there is a poor development of technology in the sector.

“…Landraces are a potential source of original traits and new variability [90] desirable to be used in plant breeding programs. There is no doubt that the landraces are adapted to a specific environment and region [91]. Furthermore, the main reason to use landraces is to bring novel favorable alleles to a breeding population [92].…”

“…Furthermore, the main reason to use landraces is to bring novel favorable alleles to a breeding population [92]. The local landraces are rich in diverse genetic materials and are a good source of important genes such as resistance to biotic and abiotic stresses and quality traits [91] and have a better capacity to absorb and utilize N under low N fertilization conditions [93].…”

Assessment of Nitrogen Use Efficiency in Algerian Saharan Maize Populations for Tolerance under Drought and No-Nitrogen Stresses

et al. 2022

Increasing drought incidence and infertile soils require the improvement of maize for nitrogen use efficiency (NUE) under drought conditions. The objectives were to assess tolerance and genetic effects of Algerian populations under no-nitrogen and water stress. We evaluated a diallel among six Algerian maize populations under no-nitrogen vs. 120 kg/ha N fertilization and drought vs. control. Variability was significant among populations and their crosses for NUE under drought. Additive genetic effects could be capitalized using the populations BAH and MST, with high grain nitrogen utilization efficiency (NUtE). The most promising crosses were SHH × AOR with no-nitrogen supply under both water regimes for NUtE, AOR × IGS, under water stress for partial factor productivity (PFP), and well-watered conditions with nitrogen supply for protein content; AOR × IZM for agronomic nitrogen use efficiency (AE) under water stress; and AOR × BAH for grain nutrient utilization efficiency (NUtE) under well-watered conditions with nitrogen. These parents could be promising for developing drought-tolerant or/and low nitrogen hybrids to improve these traits. Maximum heterosis could be exploited using those populations and crosses. Reciprocal recurrent selection could be used to take advantage of additive and non-additive gene effects found based on estimations of genetic parameters.

“…For genetic improvement, aside from sequencing data, an array of genetic resources and biparental populations like doubled haploids (DHs), F2 or F2-derived F3 populations, recombinant inbred lines (RILs), backcrosses, near-isogenic lines (NILs), nested association mapping (NAM), and multiparent advanced generation inter-cross (MAGIC) populations are essential for linking gene(s)/QTLs to specific traits. The identified marker–trait associations can then be harnessed for crop enhancement or development using marker-assisted recurrent selection (MARS), marker-assisted backcross breeding (MABB), and genomic selection (GS) approaches [ 37 , 68 ].…”

Advances in genomics resources have facilitated the evolution of cereal crops with enhanced yield, improved nutritional values, and heightened resistance to various biotic and abiotic stresses. Genomic approaches present a promising avenue for the development of high-yielding varieties, thereby ensuring food and nutritional security. Significant improvements have been made within the omics domain, specifically in genomics, transcriptomics, and proteomics. The advent of Next-Generation Sequencing (NGS) techniques has yielded an immense volume of data, accompanied by substantial progress in bioinformatic tools for proficient analysis. The synergy between genomics and computational tools has been acknowledged as pivotal for unravelling the intricate mechanisms governing genome-wide gene regulation. Within this review, the essential genomic resources are delineated, and their harmonization in the enhancement of cereal crop varieties is expounded upon, with a paramount focus on fulfilling the nutritional requisites of humankind. Furthermore, an encompassing compendium of the available genomic resources for cereal crops is presented, accompanied by an elucidation of their judicious utilization in the advancement of crop attributes.
