摘要

Three basic populations of Reid population (PH6WC) x Non-Reid population (PH4CV), Reid population (PH6WC) x DOM population (M5972), Non-Reid population (PH4CV) x DOM population (M5972) were constructed. Haploid technique was used to obtain haploid populations, whose distorted segregation were detected by SSR markers. The populations of PH6WC x PH4CV, PH6WC x M5972, PH4CV x M5972 obtained 45, 40, and 34 diversity markers, respectively. Segregation distortion results showed that three markers were skewed in the haploid population based on PH6WC x PH4CV and PH6WC x M5972, both of which were biased toward maternal PH6WC with segregation distortions frequencies at 6.67% and 7.50%, respectively. PH4CV x M5972 based haploid population did not detect distorted segregation sites.
