'Niigata S3' is a new strawberry (Fragaria × ananassa Duch.) cultivar that is early flowering and possesses high soluble solid content and good coloration. It was selected from a cross between Kei812 (seed parent) and 'Asuka-Ruby' (pollen parent). The first harvest date of 'Niigata S3' was December 27, 34 days earlier than 'Echigohime' and 9 days earlier than 'Asuka-Ruby' (means of 2007 and 2008). The marketable yield of 'Niigata S3' was 85% of 'Echigohime', 107% of 'Asuka-Ruby', while the early yield was 145% of 'Echigohime', 85% of 'Asuka-Ruby' (based on 2007 and 2008 means). The shape of the fruit is long conical, and its skin color medium-red. The fruit skin hardness of 'Niigata S3' was 31.5 g/mm(2), which was harder than 'Echigohime', and its average soluble solid content was 11.4%, which was higher than the values for 'Echigohime' and 'Asuka-Ruby' (2008). Furthermore, 'Niigata S3' did not bear apical overripe fruit. This new cultivar is adaptable to the climatic conditions of Niigata, as well as other regions that experience low winter temperatures and insolation.
“新泻 S3”是一种新型草莓（Fragaria × ananassa Duch.）品种，具有早花、高可溶性固形物含量和良好色泽等特点。它是由 Kei812（母本）和“飞鸟红宝石”（父本）杂交选育而成。“新泻 S3”的首次收获日期为 12 月 27 日，比“越后姬”早 34 天，比“飞鸟红宝石”早 9 天（2007 年和 2008 年平均值）。“新泻 S3”的商品产量为“越后姬”的 85%，“飞鸟红宝石”的 107%，而早期产量则为“越后姬”的 145%，“飞鸟红宝石”的 85%（基于 2007 年和 2008 年的平均值）。果实形状为长圆锥形，果皮颜色为中红色。“新泻 S3”的果皮硬度为 31.5 g/mm(2)，比“越后姬”硬，平均可溶性固形物含量为 11.4%，高于“越后姬”和“飞鸟红宝石”（2008 年）的值。此外，“新泻 S3”没有顶端过熟果实。该新品种适应新泻的气候条件，以及其他冬季温度低、光照不足的地区。
