single segment substitution linegrain shapequantitative trait locusRice grain shape is one of the important factors affecting grain quality and yield, but it is liable to be influenced by genetic backgrounds and environments. The chromosome single segment substitution lines (SSSLs) in rice have been ...
Single-segment substitution linesStigma exsertion rateQTL detectionPyramiding lineEpistasisSeed yield is one of the main limitations in hybrid rice production. The improvement of stigma exsertion rate (SER) of male sterility lines is essential for the higher seed yield in hybrid rice. Wild rice ...

Single segment substitution line (SSSL) libraries are an ideal platform for breeding by design. To develop SSSLs-Xihui18 covering the whole genome, a novel rice chromosome segment substitution line (CSSL), Z783, carrying two substitution segments (average length of 6.55 Mb) on Chr.4 and Chr...
single segment substitution linesQTL interactionRice grain size is a quantitative trait controlled by multiple genes. They can be dissected into a single segment substitution line (SSSL), which is of great significance for their genetic mechanism study and breeding by design.Z492, a chromosome ...
single-segment substitution lineyield componentsEpistasis is an important genetic component in determining the phenotype of complex quantitative trait. In this article, 12 single-locus heterozygotes and 66 double-locus heterozygotes were developed and then were applied to assay QTL epistasis for four ...
