Such selection was affected by available gene pools, continuing sources of genetic diversity from wild relatives andmutations, natural selection pathways fromstabilising to directional, and both allo- and auto-polyploidy, to result in unique gene pool patterns for each crop (Hancock, 2012b; Cortes et al., 2013). Thedistribution of wheatwas expanded greatlywith the addition of the Aegilops tauschii D genome to tetraploid durum wheat, thereby enabling hexaploid wheat to adapt to a much wider agroecological range from the subtropics to high latitudes, and to provide a wider diversity of food uses (Hancock, 2012c)... date: 2019 date_type: published publisher: John Wiley & Sons pagerange: 159-188 refereed: TRUE isbn: 978-1-119-18064-7 book_title: Food Security and Climate Change editors_name: Yadav, S S editors_name: Redden, R J editors_name: Hatfield, J L editors_name: Ebert, A W citation: Redden, R J and Upadyaya, H D and Dwivedi, S L and Vadez, V and Abberton, M and Amri, A (2019) Role of Plant Genetic Resources in Food Security.
