Norin PL 9 was developed by using Ketan Nangka as a source of wide-compatibility (WC). It has japonica-like characteristics and a compatibility with several indica as well as with japonica varieties. The WC varieties, including Norin PL 9, are expected to contribute to the rice breeding program, especially indica-japonica cross breeding, by means of their broad capabilities of overcoming sterility problems caused by remote crossing.
