Heterosis, means that the first-generation hybrids show the better performance than each parent, which is a biological phenomenon among crop production
We found that the centromere sequences of the doubled haploid (DH) lines in Brassica rapa were heterozygous
Three DH lines (HHE, XJD4, and Z16) and one highly inbred line (YTBJ) were used to re-sequence (30x) and detect variants compared with the Brassica rapa reference genomes version 3.0
Summary
Heterosis, means that the first-generation hybrids show the better performance than each parent, which is a biological phenomenon among crop production.
