Breeding and biotechnology for improving berry nutritional quality

Area of Science:

• Plant breeding and biotechnology
• Agricultural science
• Food science

Background:

• Plant metabolism manipulation for bioactive compounds is challenging.
• Genetic and environmental factors influence bioactive compound accumulation, often overlooked in marketing.
• Developing new cultivars requires exploring novel sources of Quality Attributes (QA) and Nutritional Attributes (NA).

Purpose of the Study:

• To evaluate scientific evidence for breeding and biotech programs focused on nutritional value and fruit quality.
• To explore new sources of QA and NA for developing improved fruit genotypes.
• To establish reliable screening methods for high-nutritional-quality genotypes.

Main Methods:

• Evaluation of scientific evidence using defined criteria.
• Exploration of wild species (e.g., F. virginiana glauca, F. vesca, R. parvifolium) as sources of bioactive compounds.
• Utilizing methods for detecting fruit total anthocyanin content (TAC), total phenolic (TPH), sugars, total acidity, and fruit color.

Main Results:

• Wild strawberry species show potential for bioactive compounds, while wild raspberry germplasm did not improve nutritional quality.
• TAC and TPH detection methods, alongside other quality parameters, are effective for screening breeding populations.
• Nutritional Attributes (NA) can aid in assessing the substantial equivalence of transgenic and control fruits.

Conclusions:

• Developing new fruit varieties with enhanced nutritional value requires careful selection and screening.
• Established analytical methods provide tools for efficient identification of high-quality genotypes.
• Nutritional profiling is crucial for both breeding advancements and regulatory assessments of novel fruit products.
