Early-inbreeding depression in Vaccinium myrtillus and V-vitis-idaea.

Primary tabs

Guillaume, Patricia [N/a] Jacquemart, Anne-Laure [UCL]

Fertility parameters were estimated in Vaccinium myrtillus and V. vitis-idaea after self- and cross-pollinations performed in growth chamber. We showed a drastic decrease in fertility after self-pollination as compared to cross-pollination. Number of plump seeds per berry was compared with previous field data. In both species, growth room conditions improved plump seed number after cross-pollination but not after self-pollination. In addition, in order to enhance resources supply to young developing fruits, cytokinin application was tested in V. myrtillus but no effect was detected. We hypothesize that the partial self-sterility is due to inbreeding depression based on the expression of recessive lethals.
