The Early Girl tomato is a medium globe type F1 hybrid popular with home gardeners because of its early fruit ripening. Early Girl is an indeterminate growth variety, meaning that it produces flowers and fruit until killed by frost or some other external factor (in contrast to determinate varieties, which grow into a limited, predefined shape and are most productive for a single, larger harvest before dying or tapering off with minimal new growth/fruit). It is tall-growing and needs support as the plant grows. Fruit maturity claims range from 50 to 62 days from transplanting, which appeals to growers in climates with shorter frost-free seasons. Early Girl can tolerate temperatures as low as 40 °F,〔(【引用サイトリンク】title=Early Girl Tomato )〕 and is well-suited for hot, dry climates.〔(【引用サイトリンク】title=Best Tomatoes for Hot, Dry Climates )〕 Plants are reliable and prolific. The ripe fruit is about the size and shape of a tennis ball—very much a standard tomato—and weighs 4 to 8 ounces (~130g). It has a bright color and good flavor. Early Girl VF hybrid is verticillium and fusarium wilt (strain I) resistant. The VFF hybrid is resistant to fusarium wilt strains I & II. An open-pollinated version has also been bred, although it is not widely available. ==History== Based on a short-season hybrid tomato developed in France, the Early Girl was originally distributed in the United States by PetoSeed Co., a major agricultural seed supplier. The variety was named "Early Girl" by PetoSeed boardmember Joe Howland to complement the company's popular "Better Boy" tomato. Seed catalog Burpee Seeds struck an exclusive three-year deal for the new variety, and featured it on the cover of its 1975 Spring catalog.〔 Since 2005, Monsanto Company is the primary producer of Early Girl tomato seeds, after acquiring Seminis corporation and its patent on the hybrid. Though the plant is a hybrid, the Early Girl cultivar is no longer under plant variety protection. Some farmers have worked to stabilize an open-pollinated version. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Early Girl」の詳細全文を読む スポンサード リンク
