1 potato is in fact the world's fourth largest food crop, with a global annual yield of around 330 million tonnes.
in an international project
2 several years, researchers have successfully recorded its complete chemical
3, deciphering and organising hundreds of millions of pieces of
4 coding.
by mapping the plant's genome scientists can locate the
5 that control various traits, like colour, starchiness and flavour, leading to the creation of improved varieties at a much quicker pace.
professor iain gordon from the james hutton institute in dundee, which headed the british team, said the genome sequence would allow breeders to develop new types that are more
6,
7 to pests and diseases and easier to cultivate.
he said the breakthrough could help to meet the challenge of feeding the world's soaring population.
