Genetic effects of F1 pollen sterility genes S-b, S-d and S-e in rice (Oryza sativa L.)
An experimental population commonly used in genetic analyses of gene or quantitative trait loci (QTLs) in rice is chromosome segment substitution lines (CSSLs). In the present study, with the typical indica variety Guangluai 4 as a donor and japonica variety Taichung 65 as a recipient, seven CSSLs c...

| description | An experimental population commonly used in genetic analyses of gene or quantitative trait loci (QTLs) in rice is chromosome segment substitution lines (CSSLs). In the present study, with the typical indica variety Guangluai 4 as a donor and japonica variety Taichung 65 as a recipient, seven CSSLs carrying F1 pollen sterility genes S-b, S-d, S-e, S-b/S-d, S-b/S-e, S-d/S-e, and S-b/S-d/S-e were obtained by specific selection for the target genes, non-specific selection for the genome of the recurrent parents in four backcross populations (BC1F2, BC2F2, BC3F2 and BC3F3). We evaluated the genetic effect of the F1 pollen sterility genes using 35 F1 hybrid individuals in crosses derived from CSSLs and Taichung 65. Pollen fertility of F1 hybrid plants was observed and the results indicated that the single genes S-b, S-d and S-e can cause 67.7%, 14.6% and 53.2% of pollen sterility, respectively. Multiple genes S-b/S-d, S-b/S-e, S-d/S-e, and S-b/S-d/S-e can cause 76.6%, 85%, 68.7%, and 93% of pollen sterility, respectively. |
