Abstract

Abstract: A segregation population derived from a cross of two indica cultivars,Erqiuai No.1 and Minghui63, which have significant differences in seed storability,was assessed, and the seed storability was identified by artificial aging protocol. The results indicated that the genetic of seed storability phenotype in Erqiuai No.1 conformed to recessive epistatic genetic model and seed storability phenotype was recessive. Furthermore,a series of breeding materials with seed storability were obtained and laid a sound foundation for rice storability breeding.

Key words: rice（Oryza sativa L.）, seed storability, genetic, breeding
