N2 - Hybrid sterility of the cross between Silewah, an Indonesian native variety and Hayakogane, a Hokkaido rice variety in Japan was confirmed to be caused by anther indehiscence, based on a lot of spikelets with fewer numbers than 3 of dehiscent anthers and fewer numbers of pollens poured onto stigma per spikelet in Silewah/Hayakogane F1. In Silewah/Hayakogane//Hayakogane BC1F1, spikelet fertility was correlated with mean number of dehiscent anthers per spikelet. So, genic analyses for hybrid sterility by anther indehiscence were conducted by scoring spikelet sterility in F2, BC1F1s and triple cross. As a result, it was concluded that the hybrid sterility was controlled by complementary action of three dominant genes. Silewah has one of the three genes and Hayakogane has the other two. It was presumed that the two genes which Hayakogane possesses were derived from those of Aikoku, an old native variety in Japan.
