Segregation Distortion Analysis of Molecular Markers in RIL Population of Brassica napus
摘要
Abstract
A genetic linkage map comprising 733 molecular markers of Brassica napus was constructed using Fl0 population consisting of 124 reeombinant inbred lines derived from a cross between P-inefficient cv. B104-2 and P-efficient cv. Eyouchangjia. Segregation distortion analysis was performed among the 733 polymorphic markers. The result indicated that 218 markers (29.7% ) showed significant segregation distortion(P<0,05), favoring either the marker alleles of female parent B104-2 (136,62.4%) or male parent Eyouchangjia (82,37.6%). Totally, 24 segregation distortion regions (SDRs) were detected among 13 different chromosomes. Based on this result, the phenomenon and causes for the segregation distortion were analyzed and discussed in this paper.关键词
