Aneeta has more than 20 years' experience in agricultural research in Australia and overseas. She has made a number of contributions in plant breeding and Molecular Genetics. She has developed DNA fingerprinting keys, the first of its kind in the world, for the identification of radish cultivars. She has successfully created a trigenomic hexaploid, ‘Super Brassica’ from the interspecific hybridisation between B. napus and B. nigra. After completing her PhD at UWA in 2010, Aneeta joined Canola Breeders Western Australia Pty Ltd. for canola crossing programme and in lupin marker project at UWA and CSIRO, where she was involved in developing molecular marker tools for improving the adaptation of wild and domesticated lupin. Aneeta also worked in tedera marker project at UWA and DPIRD, where she was responsible for in-vitro seed germination, the assessment of genetic diversity, the selection of hybrids useful in developing new cultivars, and evaluation of out-crossing rates. In 2016, she joined Batley lab where she is primarily responsible for assessing genetic variation and genotype screening with traits of interest using different techniques of genotyping by sequencing (GBS) methods such as Restriction site Associated DNA Sequencing (RAD-Seq), double digest RAD-seq (ddRAD-Seq), skim sequencing and genome-wide association studies with the Illumina Infinium HD Assay. Currently, her research also involves interspecific crossing among Brassicaceae species to capture useful genes and to produce a population of trigenomic Brassica hexaploids with greater genetic variation to develop a new crop species that may be suitable for vegetables, oilseed crops or condiments which are more vigorous, better adapted and higher yielding than their diploid and tetraploid progenitors.
Plant genetics and genomics, wide hybridisation, phenotypic and genotypic characterisation, trait association, seed testing and quality control
Interspecific and intergeneric hybridisation, polyploid induction, cytogenetics, in-vitro culture, high throughput genotyping
Interspecific hybridisation is a valuable tool for transferring traits from one species to another. Successful interspecific crosses depends on diverse genotype selection and enhanced performance through heterosis. Estimates of genetic diversity and the relationships among germplasm collections are very useful for diverse genotypes selection, identification of variation within traits, making crosses, mapping and potentially for production of new breeding lines/cultivars. The breeding target of Brassica at the hexaploid level has potential for greater disease resistance and wider adaptation to varied environments.
