Eleven F1 rice hybrids were developed by using the genetic male sterile lines having the backgrounds of Korean variety. The average heterosis, heterobeltiosis and standard heterosis for grain yield were 15.2%, 8.7% and 17.9%, respectively. Significant heterobeltiosis for number of grains per panicle was observed. The leaf blast reaction of the hybrids was mostly similar to that of the more resistant pare1542nt. Amylose content of the hybrids ranged from 20.5% to 22.5% and protein content from 10.4% to 11.1%. The degrees of alkali digestion value, white center or hite belly, clearance and heading date of the hybrids were almost the same as their par
