| Abstract: | Guiyuan A,developed from the cross of Bo A/（Longtepu B/H14∥H14）F3 and its subsequent backcrosses by the Rice Research Institute of Guangxi Academy of Agricultural Sciences,is a new indica CMS line in hybrid rice.It was technically certified in Guangxi in September,2010.It is characteristic of strong tillering ability,large panicle with many spikelets,short growth duration,stable and complete male sterility,high stigma exsertion,high out-crossing rate,good sensitivity to GA3 and easiness for multiplication and hybrid seed production.The F1 hybrids derived from Guiyuan A and several restorer lines showed a higher yield than the control hybrids with similar maturity in a preliminary yield trial in 2010. |
