    • The subject invention relates in part to the discovery of a spontaneous sunflower mutation. The subject invention involves an ‘early’ mutation and related inbred/hybrid development. The subject invention further provides a single dominant gene that confers earliness in sunflower inbred isolines and near isogenic hybrids. There is no known prior teaching or suggestion of this gene's utility for hybrid development in the industry. The subject indention also provides a new and distinctive sunflower inbred line designated H 120R. The invention includes seeds that possess this mutated gene, plants produced by growing these seeds, and progeny thereof that possess this mutated gene and the associated earliness trait. The subject invention also includes methods for producing such sunflower seeds and plants, including inbreds and hybrids. Such plants can be produced by, for example, crossing such an inbred line with itself or with another sunflower line.
    • 本发明部分地涉及自发向日葵突变的发现。 本发明涉及“早期”突变和相关近交/杂种发育。 本发明进一步提供了赋予向日葵近交等位基因和近等基因杂种的早熟的单一优势基因。 目前还没有已知的这个基因在业界对混合发育的实用性的教导或建议。 主题缩写还提供了一个新的和独特的向日葵自交系,指定为H 120R。 本发明包括具有该突变基因的种子,通过种植这些种子产生的植物,以及具有该突变基因和相关早熟性状的后代。 本发明还包括用于生产这种向日葵种子和植物的方法,包括近交系和杂交种。 这样的植物可以通过例如与其自身或另一个向日葵系交叉这样的自交系来生产。
