We present a fast and reliable method to quantify vitamin C in Lactuca spp. using UPLC-UV, potentially transferable to other plants. The key steps are the sample preparation and vitamin C extraction under stable conditions, the reduction of dehydroascorbic acid to ascorbic acid and the optimization of the chromatographic procedure.

Characterizing root system traits is one of the areas of research that is still in its infancy, particularly in sugarcane. Integrating multiple approaches to precisely phenotype sugarcane roots leads to comprehensive and holistic results, enabling the utilization of identified traits and mechanisms for conventional and molecular breeding.
FAQs
Genetic variation provides the differences in plant traits that breeders can evaluate and use. Some variants may support higher yield, improved quality, disease resistance, drought tolerance, or better adaptation to local conditions. Without this diversity, selection has fewer useful options, so conserving valuable crop variation also maintains resources for future breeding and biological research.
Controlled crosses bring together selected parent plants so their offspring may inherit favorable traits from both. Breeders then examine the resulting plants and select individuals with desirable characteristics. Repeating crossing and selection can assemble useful combinations, although the outcome depends on the genetic variation present in the parents and the traits being evaluated.
Molecular markers help researchers track genes or genomic regions linked to traits such as disease resistance or drought tolerance. This information can assist selection by indicating which offspring are more likely to carry a desired trait, complementing observations of plant performance. The approach connects measurable genetic information with breeding decisions and trait evaluation.
A program begins by identifying useful variation and choosing plants with relevant traits. Breeders may make controlled crosses, grow and evaluate the offspring, and select individuals that show favorable characteristics. Molecular markers can help follow linked genes during selection. The process may also consider yield, quality, resilience, and adaptation to intended growing conditions.
A variety that performs well in one setting may not perform equally well elsewhere because growing conditions influence plant performance. Breeding therefore considers adaptation to local environments alongside yield, quality, and resilience. Evaluating traits in relevant conditions helps identify varieties suited to particular regions and supports more efficient use of available resources.
Improved varieties can support food security by combining useful productivity, quality, resilience, and resource-use characteristics. The work also preserves diversity that future breeding may require. From a biological perspective, comparing varieties and their performance under different environments helps researchers examine how genetic differences and environmental conditions interact to shape plant traits.
