| Research Abstract |
This research was focused on production potential of japonica rice in the United States. Japonica rice in the U. S. is mainly produced in California. However, California has been suffering from six consecutive year drought, which has caused more rice diversion than ever before and change in decision making strategies. On the other hand, water shortage problems do not exist in the southern rice producing states, especially in Arkansas where rice production is much greater than any other states. Upon reduction in rice acreage in California in 1991, rice production in Arkansas increased considerably, and a large portion of the increase was planted to medium grain, the type of rice popular in California.
Regarding japonica rice varieties, it had been long believed that the southern states were not suitable. According to our research, however, some varieties developed in California may be well adopted in Arkansas. It was also found during the research that rice experiment stations in individual states often have territorial behavior or "regionalism" in which they rival against one another and tend to avoid to accept varieties developed in other states. Therefore, it is necessary to keep this in mind when one investigates potential of production of a new variety.
We came to an agreement with an Arkansas rice producer, who has been partially producing japonica rice during the last few years, to provide each other with data and other production related information. This arrangement should equip us with real data for further research to evaluate potential of japonica rice production in the South, in particular. Because of strict environment protection requirements and water shortages, it is economically quite difficult to expand rice production in California. It appears that the southern states have greater potential of increase in rice production in general and japonica rice.
