Absence of a correlation between mitochondrial complementation and root weight heterosis in sugarbeets

, : Absence of a correlation between mitochondrial complementation and root weight heterosis in sugarbeets. Euphytica 24(2): 387-392

Oxidative phosphorylation of root mitochondria isolated from eleven hybrids and their parental inbreds, and of mixtures of mitochondria from the parental inbreds, were measured at four different sampling stages. All hybrids showed significant heterosis for root weight, five hybrids showed significant heterosis for total weight and five exhibited significant heterosis for sugar percentage. Mitochondria of hybrids were generally more efficient than those of their inbred parents.
