Heterozygosity analysis of spontaneous 2n female gametes and centromere mapping of the diploid Hevea brasiliensis based on full-sib triploid populations

[Objective]The evaluation of maternal heterozygosity restitution(MHR)is vital in identifying the mechanism of 2n gametogenesis and assessing the utilization value of 2n gametes.[Method]In this study,three different full-sib triploid populations were employed to evaluate the MHR of 2n female gametes of rubber clone GT1 and confirm their genetic derivation.[Result]The results indicated that the 2n female gametes of GT1 are derived from second division restitut…查看全部>>
