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)... publisher: John Wiley & Sons contributor: Yadav, S S contributor: Redden, R J contributor: Hatfield, J L contributor: Ebert, A W date: 2019 type: Book Section type: PeerReviewed format: application/pdf language: en identifier: http://oar.icrisat.org/11181/1/Role%20of%20Plant%20Genetic%20Resources%20in%20Food%20Security.pdf identifier: 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.
