Abstract

Tiller angle is one of important characters that constitute plant type with
great significance in breading. A pair of japonica/indica lines, which were
significantly different in tiller angle, were used in this study. A DH
population were constructed via anther culture of F1 hybrids. The tiller angles
of 115 DH lines were measured. QTL analysis was conducted based on the
constructed molecular linkage map. Three QTLs (qTA-9a, qTA-9b and qTA-12) were
detected on chromosome 9 and 12 respectively, Their variation were 22.7%, 11.9%
and 20.9% respectively and their additive effects were all negative, showing
this character was controlled by genes from big tiller angle parent ZYQ8. The
application of the tiller angle that was controlled by major genes and minor
genes in rice breeding is also discussed.
