Studies on breeding of hybrid rice using the Korean cytoplasmic and genetic male sterile rice. III. Yield and grain quality of the F1 rice hybrids developed by using the genetic male sterile lines having backgrounds of Korean variety



Studies on breeding of hybrid rice using the Korean cytoplasmic and genetic male sterile rice. III. Yield and grain quality of the F1 rice hybrids developed by using the genetic male sterile lines having backgrounds of Korean variety



Korean Journal of Crop Science 32(2): 151-156



Male sterile lines with cytoplasm from Korean rice varieties were used to produce 11 F1 hybrids. The average heterosis, heterosis over the better parent and standard heterosis for grain yield were 15.2%, 8.7% and 17.9%, respectively, and heterosis over the better parent was significant for the number of grains per panicle. Resistance to Pyricularia oryzae in the hybrids was similar to that of the more resistant parent of each cross.
