YC-1辣椒是以Y150-1-1为母本,PBC065为父本配制的杂交一代组合。母本Y150-1-1为2006年从海南三亚引进的尖椒品种,经多代自交选育的优良自交系;父本PBC065为2006年从亚蔬中心引进的线椒品种,经多代自交定向选育的优良自交系,抗辣椒疫病(Phytophthora capsici Leon.)。2010年配制组合,2011-2012年进行农艺性状及抗病性鉴定。该组合全生育期105 d;株高65 cm,株幅60 cm;果长20 cm,果肩宽1.6 cm,果肉厚0.2 cm;单株平均结果数58个,单果质量17.5 g;果实微弯,商品果深绿色,成熟果鲜红色;每667 m2鲜椒产量2 560 kg;抗辣椒疫病,病情指数为13.5。

YC-1 was bred by taking Y150-1-1 as female parent and PBC065 as male parent. The inbred line Y150-1-1 was introduced from Sanya in 2006 after several generations of self-cross.
