According to the recent information, a team of scientists from University of Manchester have undertaken a study to understand better the origin of rice cultivation. The study aims to help the scientific community to come up with a better collaboration between genetic and archaeological studies of rice domestication as narrated by the lead scientist Professor Terry Brown. According to the earlier studies it proved that rice was domesticated twice and the researchers mostly focused on Japonica and Indica because of their longest history of cultivation. Most of the studies show that Japonica was domesticated some 10,000 years ago in lowland Asia and Indica emerges as a hybrid form a little afterwards. Further, the new study also shows that a third variety Aus was also domesticated separately between India and Bangladesh.
In the present project, 446 samples of different wild rice varieties were studied to find common characteristics with Aus. It was found that similar genes were present in a number of wild type rice varieties found in South Asia. In view of these findings, now the farmers in Asia can select these wild varieties with specific characters and begin to cultivate them as stated by the team. According to the conclusions, it has been revealed that this archaeological evidence suggests widespread origins of rice cultivation. It is, therefore, it anticipates that our results will stimulate a more productive collaboration between genetic and archaeological studies of rice domestication, as told by Prof.Brown.
