A Critical Evaluation Revealed the 'Proto-indica' Model Rests on a Weaker Foundation and Has a Minimal Bearing on Rice Domestication

We have evaluated the 'proto-indica' model that is the proponent of multiple domestication of rice but a single origin of the key genes in 'japonica'. Attainment of non-shattering, a marker; appeared least integral to the initial phases of domestication. The other archeological d...
