The malaysian agricultural research and development institute (mardi) released the eksotika, a petite fruited self-pollinating pureline with strong solo genetic background at that time, many researchers thought that pureline homozygous cultivars were the accepted norms in their breeding programmes. This thought was strengthened by the belief that papayas do not suffer inbreeding depression upon selfing and hence hybridization between inbred lines was unlikely to bring about heterosis (hybrid vigour). indeed, the popular cultivars in that era were from the self-pollinating gynodioecious cultivars from the solo family (sunrise, kapoho and waimanalo) and the open pollinated cultivars from gynodioecious or dioecious sources. f1 papaya hybrids were not actively pursued, although globally, the seed industry for horticultural and food crops was moving rapidly towards using f1 hybrids... we can help you to establish your own plantation, all you need is to contact us.
