从数量性状基因座作图到标记辅助选择

Making the Transition from Quantitative Trait Locus Mapping to Marker-Assisted Selection

实现从数量性状基因座作图到标记辅助选择的转变包括 :( 1)寻找与QTL紧密连锁的标记 (被标记的QTL称MQTL) ;( 2 )精确估计MQTL的效应 ;( 3)将MQTL纳入现行的育种方案 ;( 4)改变现行的育种方案 ,拓展MAS的应用空间。

Making the transition from QTL mapping to MAS will involve:(1)Finding markers associated with QTL (the marked QTL will be called MQTL);(2)Estimating the effect of MQTL accurately;(3)Incorporating MQTL in the existing program;and (4)Changing the existing selection program to enable more effective utilization of MQTL. The analyses given from this paper show that it is possible to implement MAS in breeding program though the cost of genotyping is more and we can foresee that MAS will become a important selection method in the future.
