Quantitative trait loci influencing heterosis for seedling biomass and seed yield in oilseed rape

摘要

Understanding the genetic basis of early developmental and biomass traits in oilseed rape (Brassica napus var. oleifera) and investigation of possible relationships to seed yield could be potentially useful with respect to hybrid breeding. One interesting aspect that to date has not been fully elaborated is whether heterosis for seedling traits can be related to heterosis for seed yield. In this study we have mapped quantitative trait loci (QTL) influencing heterosis for morphological traits in oilseed rape seedlings grown under controlled conditions. Our aim is to compare these loci to QTL influencing heterosis for seed yield in field experiments in the same mapping population.
