The establishment of dedicated biomass&nbsp;crops&nbsp;raises huge concerns, as they can subtract land that is required for food&nbsp;production, undermining food security. In this context,&nbsp;perennial biomass crops suitable&nbsp;for cultivation on marginal lands (MALs) raise attraction, as they could supply biomass&nbsp;without&nbsp;competing for land with food supply. While these crops withstand marginal&nbsp;conditions well, their biomass yield and quality do not ensure acceptable economic&nbsp;returns to farmers and cost-effective biomass conversion into bio-based products,&nbsp;claiming genetic&nbsp;improvement. However, this is constrained by the lack of genetic&nbsp;resources for most of these crops. Here we first review the advantages of cultivating&nbsp;novel perennial biomass crops on MALs, highlighting management practices to enhance<br> the environmental and economic sustainability of these agro-systems. Subsequently, we&nbsp;discuss the preeminent breeding targets to improve the yield and quality of the biomass&nbsp;obtainable from these crops, as well as the stability of biomass production under&nbsp;MALs conditions. These targets include crop architecture and phenology, efficiency in&nbsp;the use of resources, lignocellulose composition in relation to bio-based applications,&nbsp;and tolerance to abiotic stresses. For each target trait, we outline optimal ideotypes,&nbsp;discuss the&nbsp;available breeding resources in the context of (orphan) biomass crops,&nbsp;and provide meaningful examples of genetic improvement. Finally, we discuss the&nbsp;available tools to breed novel perennial biomass crops. These comprise conventional&nbsp;breeding methods&nbsp;(recurrent selection and hybridization), molecular techniques to&nbsp;dissect the genetics of complex traits, speed up selection, and perform transgenic&nbsp;modification (genetic mapping, QTL and GWAS analysis, marker-assisted selection,&nbsp;genomic selection, transformation protocols), and novel high-throughput phenotyping&nbsp;platforms. Furthermore, novel tools to transfer genetic knowledge from model to&nbsp;orphan crops (i.e., universal markers) are also conceptualized, with the belief that their&nbsp;development will enhance the efficiency of plant breeding in orphan biomass crops,&nbsp;enabling a sustainable use of MALs for biomass provision.</p></description> </descriptions> <fundingReferences> <fundingReference> <funderName>European Commission</funderName> <funderIdentifier funderIdentifierType="Crossref Funder ID">10.13039/501100000780</funderIdentifier> <awardNumber awardURI="info:eu-repo/grantAgreement/EC/H2020/727698/">727698</awardNumber> <awardTitle>Marginal lands for Growing Industrial Crops: Turning a burden into an opportunity</awardTitle> </fundingReference> </fundingReferences> </resource>
