Biography

Dr. Robert S Kawuki is a principal research officer and his research interest hinges on studying relationships between plant phenotypes (end-user traits) and genotypes using tools, principles, and techniques available within the realms of plant breeding, all with intention of improving crop value for benefit of humankind. Accordingly, I have since 2000 undertaken crop research on staple and/or leverage commodities including soybean, banana, and cassava, and thus attained islands of success!

  Microspore embryogenesis is the developmental plasticity of juvenile male gametophytes to switch from pollen to embryo development upon exposure to in vitro stress. It is a common method for obtaining haploid and doubled haploid plants in breeding programs for development of superior varieties via haploid-diploidization which allows fast development of homozygous lines from heterozygous parents. In cassava, obtaining haploidization through traditional methods of successive selfing is difficult because of cassava’s long reproductive cycle, high heterozygosity, and inbreeding depression. As a first step towards microspore embryogenesis, callus induction following heat treatment has not been investigated in cassava. We used two elite Ugandan cassava varieties, hereafter called “genotypes”, NASE3 and NASE14, for the study of callus induction. Heat stress of 40°C for .. View More»
