The effects of two seedling abnormalities: 1) curved hypocotyl forming a loop (CH) and 2) primary root split from the tip (PRS) on several growth variables and timing of bloom onset of peanut (Arachis hypogaea L.) plants were investigated. During early ontogeny plants developed from abnormal seedlings were shorter and had shorter internodes than those developing from normal seedlings. Total biomass was lower in plants from CH seedlings only. Internode formation, leaf production and root length at the end of the assessment period were not affected by either abnormality. Neither of the abnormalities affected timing of bloom onset. Seedlings with CH and PRS abnormalities appear to be capable of recovery during growth and to bloom normally. Further studies are necessary to determine how different types of peanut seedling abnormalities affect the yield of the crop under field conditions.
