In support of Singapore’s initiative to increase food production to meet its ’30 by 30’ goal of achieving 30% of the nutritional needs of the population by 2030, the team plans to leverage their knowledge of genetics and breeding to develop vegetable cultivars with improved agronomic traits desirable for indoor farming. Some of the vegetable crops that the team are currently studying include arugula, kale, bok choy and cai xin.
The research aims to study cultivar development and create indoor-adapted desirable traits for local farmers, as well as working towards seed innovation technologies and large-scale production.
Phenotyping and whole-genome sequencing: Conducted to study the genetic and morphological diversity of the worldwide collection of kale and other leaf crop varieties, sourced from various gene banks and commercial seed companies. Harnessing the association information between the genotype and phenotype of the plants allows the researchers to select potential parental candidates for crossing and breeding to enhance the performance of the current kale varieties.
Identifying crop genetic components: The researchers also performed assays on the anti-oxidation, antimicrobial and anti-cancer properties of kale and arugula plants. In addition, the plants were screened for their metabolite contents using a liquid-chromatography mass spectrophotometer (LC-MS).
HPC resources: This project was allocated 3,000 CPU hours on NSCC Singapore’s supercomputing resources.
By characterising the genetic diversity of the vegetable crops, the team was able to understand the trait adaptability of the plants under indoor farming conditions. The results can then be used to develop genomic prediction models to select high-yielding varieties with value-added or other desirable traits of the plants as well as to develop a targeted approach in cultivar development in order to achieve speed breeding.
For indoor farmers, these crops maximise their productivity and resource-use efficiency, which may in turn improve food security and facilitate the sustainable growth of the urban farming industry in Singapore.
