Hatton’s research focused on improving the yield, disease resistance, and quality of citrus varieties. He conducted detailed studies on the physiology of citrus trees, rootstock compatibility, and the impacts of climate and soil on fruit quality. By developing better rootstocks, Hatton helped increase the resilience of citrus orchards to pests, diseases, and environmental stresses.
His work was crucial during a period when citrus growers faced challenges like citrus tristeza virus and other devastating diseases. Hatton’s efforts in breeding and selecting superior varieties contributed to sustaining and expanding citrus production worldwide.
Advances in Apple Breeding and Pomology
While Hatton made significant strides in citrus research, his legacy is perhaps most closely associated with apple breeding and pomology. The early 20th century was a period when many traditional fruit varieties were being replaced or improved upon through scientific breeding programs.
Hatton applied genetic principles and rigorous testing to develop apple varieties that were not only flavorful but also suited to various climates and resistant to common diseases like apple scab and fire blight. He emphasized the importance of selecting rootstocks that could control tree vigor and improve fruit yield and quality.
His approach to pomology was systematic and data-driven. Hatton cataloged fruit characteristics such as sugar content, acidity, texture, and storage life, which helped growers choose the best varieties for commercial production and export. He also championed the use of controlled pollination and crossbreeding techniques, which accelerated the development of new cultivars. shutdown123
