The founder crops (or primary domesticates) are the eight plant species that were domesticated by early Neolithic farming communities in southwest Asia, which formed the basis of systematic agriculture in the Middle East, North Africa, India, Persia and Europe. They consist of flax, three cereals and four pulses, and are the first known domesticated plants in the world.  Although domesticated rye (Secale cereale) occurs in the final Epi-Palaeolithic strata at Tell Abu Hureyra (the earliest instance of domesticated plant species),  it was insignificant in the Neolithic Period of southwest Asia and only became common with the spread of farming into northern Europe several millennia later. 
This list applies mainly to agriculture in southwest Asia. Rice was cultivated at the Yangtze River in East Asia around the same time,  peanuts, squashes, and cassavas had been domesticated in the New World,   and other plants were used in southwest Asia such as figs.
