| Abstract:
Five previously undescribed genetic characters have appeared in seedling populations developed in support of our peach and nectarine breeding program. One of these, Roughskin, reduces fruit pubescence. The others affect tree growth (Collar, Mini-pillar, Twister) or leaf color (Quick fade). Preliminary results suggest all are controlled by single recessive genes demonstrating dominant gene action, except for Quick fade, which demonstrates incomplete dominance. Additional observations are needed to verify the inheritance of these characters. | |
