This project was part of the ongoing research collaboration between the Australian vegetable seed industry, TIAR, and seedPurity Pty Ltd to improve standards of vegetable seed production in Australia. This project helped to develop cultural practices for management of flowering time in carrot seed crops to maximise pollination, identify floral traits for use in breeding and selection of carrorts to maximise seed yields, extend previous research outcomes to develop a group of skilled growers and agronomists within the Tasmanian carrot seed industry undertaking best practice carrot seed production, and identify key limiting factors for hybrid onion seed yields.
