The Journal of Applied Botany and Food Quality is the Open Access journal of the German Society for Quality Research on Plant Foods and the Section Applied Botany of the German Society for Plant Sciences (DBG). It provides a platform for scientists to disseminate recent results of applied plant research in plant physiology and plant ecology, plant biotechnology, plant cultivation, phytomedicine, plant nutrition, plant stress and resistance, plant microbiology, plant analysis (including -omics techniques), and plant food chemistry. The articles have a clear focus on botanical and plant quality aspects and contain new and innovative information based on state-of-the-art methodologies.

icons of sustainable development goalsSpecial Section 2022 – Applied Botany for Sustainability

Effects of climate change emerge in many ways. Among others, it has a main impact on current plant production systems. Increasing areas of marginal soil are observed, but more and more people need to be fed. To fulfill some of the sustainable development goals ( such as SDG2 Zero Hunger, SDG6 Clean Water and Sanitation, SDG12 Responsible Consumption and Production at least partially, the potential of plants need to be fully developed and exploited.

With this special section, we offer the opportunity to demonstrate how applied botany contributes to these goals. In general, every topic that uses botany to work towards the Sustainable Development Goals is welcome. We invite everyone to participate by submitting a manuscript until August 31, 2022!

This special section is also connected to the symposium “Applied Botany for Sustainability” by the Section Applied Botany of the DGB at this year’s International Conference of the German Society for Plant Sciences. If you plan to contribute to the symposium, we invite you to submit a connected manuscript to the Journal of Applied Botany and Food Quality until May 31, 2022.

Spontaneous polyploidisation of interspecific and intersectional Pelargonium hybrids during embryo rescue

by S. Plaschil, H. Budahn, E. Klocke, M. Wiedemann and K. Olbricht

Modern Pelargonium crispum hybrids (section Pelargonium) show low genetic and phenotypic variation due to the domestication effect. Species of the sections Cortusina, Ligularia, and Pelargonium are potential breeding partners at the diploid level (2n = 2x = 22). Five P. × crispum cultivars were used as seed parents and pollinated with one genotype of P. grandiflorum (section Pelargonium) and three genotypes of P. fulgidum (section Ligularia). In both combinations, embryo rescue was necessary. Embryos were rescued and cultured on Murashige & Skoog medium supplemented with phytohormones. After callus and adventitious shoot regeneration 15 viable interspecific hybrids were obtained from crossbreeding with P. grandiflorum and 11 intersectional hybrids from crossings with P. fulgidum, respectively. The hybrids were cultivated in the greenhouse until flowering. Their hybrid character was evident due to the intermediate morphological traits. Molecular investigations using dp-RAPD analysis confirmed this. Within the F1 population P. × crispum with P. grandiflorum three hybrids and after crossing with P. fulgidum one hybrid possessed larger flowers and fully developed anthers, respectively. Their ploidy level was confirmed as tetraploid using flow cytometry. Therefore, a spontaneous polyploidisation occurred during in vitro regeneration. The tetraploid F1 hybrids are fertile and could be used for further breeding.
