Panicle exsertion is an important agronomic trait involved in pollination and hybrid rice seed production. The identification of genes controlling panicle exsertion will play a central role in hybrid rice breeding. C115, a chromosome segment substitution line carrying introgression segments of Nipponbare in genetic background of indica variety 9311, had significantly shortened panicle exsertion, uppermost...
We analyzed the heredity of anther morphology in rice (Oryza sativa L.) using incomplete diallel crosses of six japonica restorer lines and eight cytoplasmic male-sterile (CMS) lines, and 48 F1 combinations resulting from these crosses. We analyzed four traits: the length of dehiscence formed in the apical (ADL) and basal (BDL) parts of the anther and the respective widths, ADW and BDW. The ratios...
Quantitative trait loci (QTL) for the length of the dehiscence that forms at the base of the anther [basal dehiscence length (BDL)] in rice (Oryza sativa L.) were analyzed using chromosome segment substitution lines (CSSLs) developed from 9311 (as the recipient) and Nipponbare (as the donor). Using composite interval mapping with QTL Icimapping software, seven QTLs were detected on Chr. 2, 7, 8, 9,...
