The potato (Solanum tuberosum) is the world's fourth most important
food crop after maize, rice and wheat with 377 million tonnes
fresh-weight of tubers produced in 2016 from 19.2 million hectares
of land, in 163 countries, giving a global average yield of 19.6 t
ha-1 (http://faostat.fao.org). About 62% of production (234 million
tonnes) was in Asia (191), Africa (25) and Latin America (18) as a
result of steady increases in recent years, particularly in China
and India. As a major food crop, the potato has an important role
to play in the United Nations "2030 Agenda for Sustainable
Development" which started on 1 January 2016
(http://faostat.fao.org). By 2030 the aim is to "ensure access by
all people, in particular the poor and people in vulnerable
situations, including infants, to safe, nutritious and sufficient
food all year round". By then, the world population is expected to
reach 8.5 billion and continue to increase to 9.7 billion in 2050.
For potatoes, the need is to increase production and improve
nutritional value during a period of climate change, a key aspect
of which will be the breeding of new cultivars for a wide range of
target environments and consumers. The aim of the book is to help
this endeavour by providing detailed information in three parts on
both the theory and practice of potato breeding. Part I deals with
the history of potato improvement and with potato genetics. Part II
deals with breeding objectives, divided into improving yield,
quality traits and resistance to the most important diseases and
pests of potatoes. Part III deals with breeding methods: first, the
use of landraces and wild relatives of potato in introgression
breeding, base broadening and population improvement; second,
breeding clonally propagated cultivars as a way to deliver potato
improvement to farmers' fields; third, as an alternative, breeding
potato cultivars for propagation through true potato seed; and
fourth, gene editing and genetic transformation as ways of making
further improvements to already successful and widely grown
cultivars. Included are marker-assisted introgression and selection
of specific alleles, genomic selection of many unspecified alleles
and diploid F1 hybrid breeding.
