METHODS AND COMPOSITIONS FOR ACCELERATED TRAIT INTROGRESSION

Compositions and methods are provided for the use of pollen-inhibitor genes and/or color marker genes in accelerated trait introgression. Compositions and methods are also provided for introducing a pollen-inhibitor gene and/or a color marker gene in close proximity to a trait locus of interest. Breeding methods and methods for selecting plants comprising a trait locus of interest in close proximity to at least one pollen-inhibitor gene and/ or color marker gene are also disclosed. The methods and compositions employ at least one pollen-inhibitor gene and /or color marker gene to provide an effective system for accelerated trait introgression in the genome of a plant. 提供了用于在加速的性状渐渗中使用花粉抑制剂基因和/或颜色标记基因的组合物和方法。还提供了用于在靠近目的性状基因座处引入花粉抑制剂基因和/或颜色标记基因的组合物和方法。还披露了育种方法和用于选择植物的方法，这些植物在靠近至少种花粉抑制剂基因和/或颜色标记基因处包含目的性状基因座。这些方法和组合物采用至少种花粉抑制剂基因和/或颜色标记基因以提供在植物基因组中加速性状渐渗的有效系统。
