This collection features five peer-reviewed reviews on optimising rootstock health. The first chapter explores optimising rootstock health to improve root function, resource-use efficiency, sustainability and agricultural productivity. The chapter also presents a case study on tomato rootstocks as a viable strategy to overcome abiotic stresses in Ghana. The second chapter reviews the important aspects of tree growth and development in apple production which are integral to ensure product quality. The chapter discusses the importance of rootstocks and emphasises the mechanisms and morphological effects of dwarfing on rootstocks. The third chapter considers recent advances in the development and utilisation of fruit tree rootstocks, focussing primarily on apples. The chapter also reviews rootstock tolerance to both abiotic and biotic stresses. The fourth chapter discusses advances in avocado tissue culture for clonal propagation and highlights the potential of this technology for improving the sustainable supply of high-quality avocado plants to support future avocado industry growth. The final chapter addresses the challenges and opportunities in pear breeding, focussing on pear cultivars, pear rootstocks and germplasm resources. The chapter also considers the use of dwarfing as a means of improving particular traits.

Originating in Central Asia, apples are one of the most important fruits globally and are grown in over 100 countries. Apple cultivation faces a number of challenges. Increasing global competition has put the focus on lowering costs whilst further improving sensory quality and shelf-life. There is a need to reduce inputs such as water, fertiliser and labour, both to save costs and reduce environmentally-damaging emissions and pollution. There is a continual battle with fungal, viral and bacterial diseases as well as insect pests. In the long term there is a need for new varieties able to withstand disease or more extreme conditions associated with climate change. This means preserving genetic variety and exploiting new molecular breeding techniques opened up by the sequencing of the apple genome in 2010. Drawing on an international range of expertise, this collection focuses on ways of improving the cultivation of apples as a food crop at each step in the value chain, from breeding through to post-harvest storage. The book first reviews research in apple physiology and breeding. The following sections focus on cultivation techniques through to post-harvest storage, followed by a discussion of diseases and pests and their management. Concluding chapters address wider issues such as economics, consumer trends and sustainability. Achieving sustainable cultivation of apples will be a standard reference for fruit and horticultural scientists in universities, government and other research centres and companies producing apples.
