Phenotypic Variation and Molecular Marker Network Expression of Some Agronomic Traits in Rice (Oryza sativa L.) RILS of Gr 89-1×Shuhui 527

In this study, a Glutinous rice 89-1 (Gr 89-1) × Shuhui 527 recombinant inbred line population (RIL) comprising 309 F9-generations was used to screen gradient molecular markers. The phenotypic variation and distribution of eight agronomic traits obtained from multiyear multilocation samples, as well the network expression relationships between markers, were investigated. results showed that there 14 lines with significant differences in RILs, testing most consistent phenotype. correlation degree first-level markers 100%. Excluding correlations third-level grain width length, decreased an increase marker levels. RILs divided into core populations one approximate population, revealing genetic correspondence
