Abstract

Percentage of grains with chalkiness (PGWC) controlled by multi-genes is one of the main appearance quality of rice. The selection among the offspring using genetic separation directly influences quality improvements of hybrid rice. The present study focused on the segregation of PGWC, using Huanghuazhan as the female parent and CS197 as the male parent to construct hybrid rice F2 population. Molecular markers were used for genotype analysis among the extremely low and high PGWC individuals from the F2 population. The results revealed that the genotypes of 10 extremely low PGWC individual plants were 80.00% and 3.33% identical to that of Huanghuazhan and CS197, respectively. Genotype and phenotype of the most 10 individual plants were similar to Huanghuazhan. On the contrary, the genotypes of 10 extremely high PGWC individual plants were 37.78% and 32.22% identical to that of Huanghuazhan and CS197, respectively. Genotype and phenotype of the most of 10 individual plants were the similar to CS197. The extremely low and high PGWC individuals had high coincidence with the corresponding F2:3 family lines in phenotype and genotype. This is the first report on the genetic separation of PGWC in Huanghuazhan.
