In 2012, a single Spear‐shaped Leaf mutant peanut (Reg. no. GS‐11, PI 693219) (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. It was believed to be a spontaneous mutation; an inheritance study examining segregation in an F₂ population concluded single gene inheritance with incomplete dominance, and the gene was designated SpL. The unique phenotype and inheritance of this mutation makes the Spear‐shaped Leaf an interesting mutant to be preserved as a genetic stock and released to the public for researchers interested in the genetic, biochemical, and physiological aspects of leaf shape and leaf development. The Spear‐shaped Leaf mutant could also serve as a tool to measure outcrossing in the field or as a border or plot marker.

矛状叶花生遗传资源的登记

2012年，在乔治亚州沿海大学的“ Georgia-06G”育种试验田中鉴定出了单个矛状叶片突变花生（Reg。no。GS-11，PI 693219）（花生）。乔治亚州蒂夫顿市平原实验站的吉布斯研究农场。据信这是自发的突变。一项针对F ₂族群隔离的遗传研究得出结论，单基因遗传的优势不完全，该基因被命名为SpL。这种突变的独特表型和遗传特性使矛形叶片成为有趣的突变体，可以保留为遗传种群，并向对叶片形状和叶片发育的遗传，生化和生理方面感兴趣的研究人员向公众发布。Spear形的Leaf突变体还可以用作测量野外杂交的工具，或者作为边界或情节标记。
