Comparison of Germination of High Oleic ACID Lines and Traditional Cultivars of Virginia Grown Peanuts Over A Range of Temperatures.

A one-dimensional thermogradient table was used to compare germination of high oleic acid/low linolenic lines N08081olJC and N08075olCT higher oleic and less linoleic content and traditional cultivars with normal oleic and linoleic content ‘Bailey’ and ‘Champs’.  All cultivars were grown in Suffolk, VA in 2011 in the same field, harvested and dried to 7% MC (dwt basis), and stored at 0°C until seed testing in April 2012. Successful germination was counted as radicle emergence for seeds incubated in plastic boxes on three thicknesses of germination blotter paper saturated with 25 mL of distilled water.  ‘Bailey’ and ‘Champ’ had a higher germination rate compared to the high oleic lines whose germination was more variable. ‘Bailey’ and ‘Champ’ were able to germinate at lower temperatures compared to breeding lines with higher oleic. Necrotic tissue was observed on the radicles of some high oleic acid seeds after germination but not ‘Bailey’ or ‘Champ’.
