| 0 | PI 693219 | 'Spear-shaped Leaf' | Arachis hypogaea L. | Georgia, United States | S9 | | Not Available | 2020 | DEVELOPED | | | | | | Genetic material | In 2012, a single Spear-shaped Leaf mutant peanut (Arachis hypogaea L.) plant was identified in a breeding trial plot of ‘Georgia-06G’ at the University of Georgia, Coastal Plain Experiment Station’s Gibbs Research Farm in Tifton, GA. Believed to be a spontaneous mutation, an inheritance study examining segregation in an F2 population concluded single gene inheritance with incomplete dominance, the gene was designated SpL (Branch, 2017). The Spear-shaped Leaf mutant has narrow leaflets that are narrower at the base, broader toward the middle of the leaflet, then come to a point resembling a spear head. In F2:3 progeny rows of a population derived from crossing Georgia-06G to the Spear-shaped Leaf mutant, Spear-shaped Leaf plants were significantly taller than normal leaf plants by 6.8 cm. Leaflet length was similar for Spear-shaped Leaf and normal plant types, 46.1 vs. 46.6 mm respectively. However, leaflet width was significantly more narrow for the Spear-shaped Leaf mutant (15.1 mm) compared to the normal leaf progeny (21.8 mm). Pod weight and percentage of sound mature kernels was significantly impacted in the mutant progeny with 245.4 g of pods and 60.9 % sound mature kernels compared to the normal leaf progeny with an average of 318.7 g of pods and 68.0 % sound mature kernels, respectively. The Spear-shaped Leaf mutant plants grow adequately, however some pleiotropic effects of the mutation are apparent, including a taller plant and reduced yield. | 2101090 | PI 693219 |
